WCF Architecture

2009-09-12T02:55:00.000-07:00

This document provides a high-level view of the Windows Communication Foundation (WCF) architecture. It is intended to explain key concepts in WCF and how they fit together. There are a few code examples to further illustrate the concepts, but code is not the emphasis of this document.

The rest of this document is organized in two main sections:

WCF Fundamentals: Covers key concepts in WCF, terms, and architectural components.
Code Examples: Provides a few short code examples intended to illustrate and reify the concepts covered in WCF Fundamentals.

WCF Fundamentals

A WCF Service is a program that exposes a collection of Endpoints. Each Endpoint is a portal for communicating with the world.

A Client is a program that exchanges messages with one or more Endpoints. A Client may also expose an Endpoint to receive Messages from a Service in a duplex message exchange pattern.

The following sections describe these fundamentals in more detail.

Endpoints

A Service Endpoint has an Address, a Binding, and a Contract.

The Endpoint's Address is a network address where the Endpoint resides. The EndpointAddress class represents a WCF Endpoint Address.

The Endpoint's Binding specifies how the Endpoint communicates with the world including things like transport protocol (e.g., TCP, HTTP), encoding (e.g., text, binary), and security requirements (e.g., SSL, SOAP message security). TheBinding class represents a WCF Binding.

The Endpoint's Contract specifies what the Endpoint communicates and is essentially a collection of messages organized in operations that have basic Message Exchange Patterns (MEPs) such as one-way, duplex, and request/reply. TheContractDescription class represents a WCF Contract.

The ServiceEndpoint class represents an Endpoint and has an EndpointAddress, a Binding, and a ContractDescription corresponding to the Endpoint's Address, Binding, and Contract, respectively (see Figure 1).

EndpointAddress

An EndpointAddress is basically a URI, an Identity, and a collection of optional headers as shown in Figure 2.

An Endpoint's security identity is normally its URI; however, in advanced scenarios the identity can be explicitly set independent of the URI using the Identity address property.

The optional headers are used to provide additional addressing information beyond the Endpoint's URI. For example, address headers are useful for differentiating between multiple Endpoints that share the same address URI.

Bindings

A Binding has a name, a namespace, and a collection of composable binding elements (Figure 3). The Binding's name and namespace uniquely identify it in the service's metadata. Each binding element describes an aspect of how the Endpoint communicates with the world.

For example, Figure 4 shows a binding element collection containing three binding elements. The presence of each binding element describes part of the how of communicating with the Endpoint. The TcpTransportBindingElementindicates that the Endpoint will communicate with the world using TCP as the transport protocol.ReliableSessionBindingElement indicates that the Endpoint uses reliable messaging to provide message delivery assurances. SecurityBindingElement indicates that the Endpoint uses SOAP message security. Each binding element usually has properties that further describe the specifics of the how of communicating with the Endpoint. For example, the ReliableSessionBindingElement has an Assurances property that specifies the required message delivery assurances, such as none, at least once, at most once, or exactly once.

The order and types of binding elements in Bindings are significant: The collection of binding elements is used to build a communications stack ordered according to the order of binding elements in the binding elements collection. The last binding element to be added to the collection corresponds to the bottom component of the communications stack, while the first one corresponds to the top component. Incoming messages flow through the stack from the bottom upwards, while outgoing messages flow from the top downwards. Therefore the order of binding elements in the collection directly affects the order in which communications stack components process messages. Note that WCF provides a set of pre-defined bindings that can be used in the majority of scenarios instead of defining custom bindings.

Contracts

A WCF Contract is a collection of Operations that specifies what the Endpoint communicates to the outside world. Each operation is a simple message exchange, for example one-way or request/reply message exchange.

The ContractDescription class is used to describe WCF Contracts and their operations. Within a ContractDescription, each Contract operation has a corresponding OperationDescription that describes aspects of the operation such as whether the operation is one-way or request/reply. Each OperationDescription also describes the messages that make up the operation using a collection of MessageDescriptions.

A ContractDescription is usually created from an interface or class that defines the Contract using the WCF programming model. This type is annotated with ServiceContractAttribute and its methods that correspond to Endpoint Operations are annotated with OperationContractAttribute. You can also build a ContractDescription by hand without starting with a CLR type annotated with attributes.

A duplex Contract defines two logical sets of operations: A set that the Service exposes for the Client to call and a set that the Client exposes for the Service to call. The programming model for defining a duplex Contract is to split each set in a separate type (each type must be a class or an interface) and annotate the contract that represents the service's operations with ServiceContractAttribute, referencing the contract that defines the client (or callback) operations. In addition, ContractDescription contains a reference to each of the types thereby grouping them into one duplex Contract.

Similar to Bindings, each Contract has a Name and Namespace that uniquely identify it in the Service's metadata.

Each Contract also has a collection of ContractBehaviors that are modules that modify or extend the contract's behavior. The next section covers behaviors in more detail.

Behaviors

Behaviors are types that modify or extend Service or Client functionality. For example, the metadata behavior thatServiceMetadataBehavior implemented controls whether the Service publishes metadata. Similarly, the security behavior controls impersonation and authorization, while the transactions behavior controls enlisting in and auto-completing transactions.

Behaviors also participate in the process of building the channel and can modify that channel based on user-specified settings and/or other aspects of the Service or Channel.

A Service Behavior is a type that implements IServiceBehavior and applies to Services. Similarly, a Channel Behavior is a type that implements IChannelBehavior and applies to Client Channels.

Service and Channel Descriptions

The ServiceDescription class is an in-memory structure that describes a WCF Service including the Endpoints exposed by the Service, the Behaviors applied to the Service, and the type (a class) that implements the Service (see Figure 6). ServiceDescription is used to create metadata, code/config, and channels.

You can build this ServiceDescription object by hand. You can also create it from a type annotated with certain WCF attributes, which is the more common scenario. The code for this type can be written by hand or generated from a WSDL document using a WCF tool called svcutil.exe.

Although ServiceDescription objects can be created and populated explicitly, they are often created behind the scenes as part of running the Service.

Similarly on the client side, a ChannelDescription describes a WCF Client's Channel to a specific Endpoint (Figure 7). The ChannelDescription class has a collection of IchannelBehaviors, which are Behaviors applied to the Channel. It also has a ServiceEndpoint that describes the Endpoint with which the Channel will communicate.

Note that, unlike ServiceDescription, ChannelDescription contains only one ServiceEndpoint that represents the target Endpoint with which the Channel will communicate.

WCF Runtime

The WCF Runtime is the set of objects responsible for sending and receiving messages. For example, things like formatting messages, applying security, and transmitting and receiving messages using various transport protocols, as well as dispatching received messages to the appropriate operation, all fall within the WCF runtime. The following sections explain the key concepts of the WCF runtime.

Message

The WCF Message is the unit of data exchange between a Client and an Endpoint. A Message is essentially an in-memory representation of a SOAP message InfoSet. Note that Message is not tied to text XML. Rather, depending on which encoding mechanism is used, a Message can be serialized using the WCF binary format, text XML, or any other custom format.

Channels

Channels are the core abstraction for sending Messages to and receiving Messages from an Endpoint. Broadly speaking, there are two categories of Channels: Transport Channels handle sending or receiving opaque octet streams using some form of transport protocol such as TCP, UDP, or MSMQ. Protocol Channels, on the other hand, implement a SOAP-based protocol by processing and possibly modifying messages. For example, the security Channel adds and processes SOAP message headers and may modify the body of the message by encrypting it. Channels are composable such that a Channel may be layered on top of another Channel that is in turn layered on top of a third Channel.

EndpointListener

An EndpointListener is the runtime equivalent of a ServiceEndpoint. The EndpointAddress, Contract, and Binding of ServiceEndpoint (representing where, what and how), correspond to the EndpointListener's listening address, message filtering and dispatch, and channel stack, respectively. The EndpointListener contains the Channel stack that is responsible for sending and receiving messages.

ServiceHost and ChannelFactory

The WCF Service runtime is usually created behind the scenes by calling ServiceHost.Open. ServiceHost (Figure 6) drives the creation of a ServiceDescription from on the Service type and populates the ServiceDescription's ServiceEndpoint collection with Endpoints defined in config or code, or both. ServiceHost then uses the ServiceDescription to create the channel stack in the form of an EndpointListener object for each ServiceEndpoint in the ServiceDescription.

Figure 8. ServiceHost object model

Similarly, on the client side, the Client runtime is created by a ChannelFactory, which is the Client's equivalent of ServiceHost.

ChannelFactory drives the creation of a ChannelDescription based on a Contract type, a Binding, and an EndpointAddress. It then uses this ChannelDescription to create the Client's channel stack.

Unlike the Service runtime, the Client runtime does not contain EndpointListeners because a Client always initiates connection to the Service, so there is no need to "listen" for incoming connections.

span style="font-family:Verdana;color:black;">Code Examples

This section provides code examples that show how Services and Clients are built. These examples are intended to reify the above concepts and not to teach WCF programming.

Defining and Implementing a Contract

As mentioned above, the easiest way to define a contract is creating an interface or a class and annotating it withServiceContractAttribute, allowing the system to easily create from it a ContractDescription.

When using interfaces or classes to define contracts, each interface or class method that is a member of the contract must be annotated with OperationContractAttribute. For example:

using System.ServiceModel;

//a WCF contract defined using an interface

[ServiceContract]

public interface IMath

 [OperationContract]

 int Add(int x, int y);

Implementing the contract in this case is simply a matter of creating a class that implements IMath. That class becomes the WCF Service class. For example:

//the service class implements the interface

public class MathService : IMath

 public int Add(int x, int y)

 { return x + y; }

Defining Endpoints and Starting the Service

Endpoints can be defined in code or in config. In the example below, the DefineEndpointImperatively method shows the easiest way to define Endpoints in code and start the service.

DefineEndpointInConfig method shows the equivalent endpoint defined in config (config example follows the code below).

public class WCFServiceApp

 public void DefineEndpointImperatively()

 //create a service host for MathService

 ServiceHost sh = new ServiceHost(typeof(MathService));

 //use the AddEndpoint helper method to

 //create the ServiceEndpoint and add it

 //to the ServiceDescription

 sh.AddServiceEndpoint(

 typeof(IMath), //contract type

 new WSHttpBinding(), //one of the built-in bindings

 "http://localhost/MathService/Ep1"); //the endpoint's address

 //create and open the service runtime

 sh.Open();

  public void DefineEndpointInConfig()

 //create a service host for MathService

 ServiceHost sh = new ServiceHost (typeof(MathService));

 //create and open the service runtime

 sh.Open();

 xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

 address="http://localhost/MathService/Ep1"

 binding="wsHttpBinding"

 contract="IMath"/>

Sending Messages to an Endpoint

The code below shows two ways to send a message to the IMath endpoint. SendMessageToEndpoint hides the Channel creation, which happens behind the scenes while the SendMessageToEndpointUsingChannel example does it explicitly.

The first example in SendMessageToEndpoint uses a tool named svcutil.exe and the Service's metadata to generate a Contract (IMath in this example), a proxy class (MathProxy in this example) that implements the Contract, and associated config (not shown here). Again, the Contract defined by IMath specifies the what (i.e., the operations that can be performed), while the generated config contains a Binding (the how) and an address (the where).

Using this proxy class is simply a matter of instantiating it and calling the Add method. Behind the scenes, the proxy class will create a Channel and use that to communicate with the Endpoint.

The second example in SendMessageToEndpointsUsingChannel below shows communicating with an Endpoint using ChannelFactory directly. In this example, instead of using a proxy class and config, a Channel is created directly usingChannelFactory.CreateChannel. Also, instead of using config to define the Endpoint's address and Binding, the ChannelFactory constructor takes those two pieces of information as parameters. The third piece of information required to define an Endpoint, namely the Contract, is passed in as the type T.

using System.ServiceModel;

//this contract is generated by svcutil.exe

//from the service's metadata

public interface IMath

 [OperationContract]

 public int Add(int x, int y)

 { return x + y; }

//this class is generated by svcutil.exe

//from the service's metadata

//generated config is not shown here

public class MathProxy : IMath

...

public class WCFClientApp

 public void SendMessageToEndpoint()

 //this uses a proxy class that was

 //created by svcutil.exe from the service's metadata

 MathProxy proxy = new MathProxy();

 int result = proxy.Add(35, 7);

 public void SendMessageToEndpointUsingChannel()

 //this uses ChannelFactory to create the channel

 //you must specify the address, the binding and

 //the contract type (IMath)

 ChannelFactory factory=new ChannelFactory(

 new WSHttpBinding(),

 new EndpointAddress("http://localhost/MathService/Ep1"));

 IMath channel=factory.CreateChannel();

 int result=channel.Add(35,7);

 factory.Close();

Defining a Custom Behavior

Defining a custom Behavior is a matter of implementing IServiceBehavior (or IChannelBehavior for client-side behaviors). The code below shows an example behavior that implements IServiceBehavior. In IServiceBehavior.ApplyBehavior, the code inspects the ServiceDescription and writes out the Address, Binding, and Contract of each ServiceEndpoint, as well as the name of each Behavior in the ServiceDescription.

This particular behavior is also an attribute (inherits from System.Attribute), making it possible to apply declaratively as will be shown below. However, behaviors are not required to be attributes.

[AttributeUsageAttribute(

 AttributeTargets.Class,

 AllowMultiple=false,

 Inherited=false)]

public class InspectorBehavior : System.Attribute,

 System.ServiceModel.IServiceBehavior

 public void ApplyBehavior(

 ServiceDescription description,

 Collection behaviors)

 Console.WriteLine("-------- Endpoints ---------");

 foreach (ServiceEndpoint endpoint in description.Endpoints)

 Console.WriteLine("--> Endpoint");

 Console.WriteLine("Endpoint Address: {0}",

 endpoint.Address);

 Console.WriteLine("Endpoint Binding: {0}",

 endpoint.Binding.GetType().Name);

 Console.WriteLine("Endpoint Contract: {0}",

 endpoint.Contract.ContractType.Name);

 Console.WriteLine();

 Console.WriteLine("-------- Service Behaviors --------");

 foreach (IServiceBehavior behavior in description.Behaviors)

 Console.WriteLine("--> Behavior");

 Console.WriteLine("Behavior: {0}", behavior.GetType().Name);

 Console.WriteLine();

Applying a Custom Behavior

All behaviors can be applied imperatively by adding an instance of the behavior to the ServiceDescription (or the ChannelDescription on the client side). For example, to apply the InspectorBehavior imperatively you would write:

ServiceHost sh = new ServiceHost(typeof(MathService));

sh.AddServiceEndpoint(

 typeof(IMath),

 new WSHttpBinding(),

 "http://localhost/MathService/Ep1");

//Add the behavior imperatively

InspectorBehavior behavior = new InspectorBehavior();

sh.Description.Behaviors.Add(behavior);

sh.Open();

Additionally, behaviors that inherit from System.Attribute may be applied declaratively to the service. For example, because InspectorBehavior inherits from System.Attribute, it can be applied declaratively like this:

[InspectorBehavior]

public class MathService : IMath

 public int Add(int x, int y)

 { return x + y; }

Summary

WCF Services expose a collection of Endpoints where each Endpoint is a portal for communicating with the world. Each Endpoint has an Address, a Binding, and a Contract (ABC). The Address is where the Endpoint resides, the Binding ishow the Endpoint communicates, and the Contract is what the Endpoint communicates.

On the Service, a ServiceDescription holds the collection of ServiceEndpoints each describing an Endpoint that the Service exposes. From this description, ServiceHost creates a runtime that contains an EndpointListener for each ServiceEndpoint in the ServiceDescription. The Endpoint's address, Binding, and Contract (representing the where, what, and how) correspond to the EndpointListener's listening address, message filtering and dispatch, and channel stack, respectively.

Similarly, on the Client, a ChannelDescription holds the one ServiceEndpoint with which the Client communicates. From this ChannelDescription, ChannelFactory creates the channel stack that can communicate with the Service's Endpoint.

Personal Quotes

(December 2001, about Hrithik Roshan): I wish I looked as good as he does. And I wish I danced as well as he does!

Yes, I do have a close circle of friends and I am very fortunate to have them as friends. I feel very close to them I think friends are everything in life after your family. You come across lots of people all the time but you only make very few friends and you have to be true to them otherwise what's the point in life?

I'd rather sink trying to be different, than stay afloat like everyone else

I cannot repay my fans for what they have done for me, they have given me so much love and that love has taken me to the number 1 position where I am today, the only thing I can do for my fans is to never stop working, and to do films till the very end, it is the only way I can express my love for them.

To me, Devdas is the end of love stories. I've portrayed an obsessed lover, a nice lover, an angry lover, a romantic lover. And now I've played Devdas. For someone who doesn't even like love stories, I've played an awful lot of lovers. Personally speaking, I wouldn't see any of the romantic films I've acted in.

I'm the luckiest man in the world and I don't want to hide from the faces I'm acting for. So I don't surround myself with guards, I've never given an interview in which I've said I feel bad that I can't go shopping or I can't go to Chowpatty and eat bhelpuri without being mobbed. I'm not the kind of guy who goes out wearing dark glasses (I don't think I'm a big enough star to hide behind them, honest). I go to see movies in the cinema theatres, I go to restaurants with my family and friends even though I know people are going to disturb me there.

God has become a generic term like `mind blowing.' It is embarrassing. I would have said that to Amitabh Bachchan, Naseeruddin Shah, Nana Patekar. I used to tell them I want to stand in the same space as you. I've told Kamal Haasan, I just want to touch you. They are the gods of acting. When people call me God, I say, no, I'm still an angel or saint of acting. I still have a long way to go.

(August 2004): Awards that ignore me are losers.

(August 2004): I'm try-sexual. I try anything that's sexual.

(August 2004): I have no competition. Every year the names I'm pitted against keep changing. You can't cream the competition, you have to kill it.

I keep hearing that our films are escapist and unreal but I find our films the most real in the world. We don't have people going up in a rocket and single-handedly blowing up a meteor. We don't have a president on Air Force One saving the world or things coming out of people's stomachs. Our fantasies and escapism are real. It's just people singing and dancing in the street. If England had won the World Cup you would have seen people singing and dancing like that.

You're not allowed to lobby as in you're not allowed to meet the Academy members, talk to them or even make a call to them. You just keep advertising in the 'For Consideration For Oscars' category. We took out full page ads in papers like Variety and Hollywood Reporter. The only good thing we did was that we advertised very frequently, it was promoted on the same scale as the biggest of films. We did it because we could afford it." (Movie Mag, May 2006)

"I felt Asoka (2001) should have been chosen for the Oscars. We had worked towards that. We had these international distributors for it. We were the first to actually release an Indian film internationally in traditionally non-Indian theaters. We spent a lot of money and lost a lot of money too. We were the first to put up boardings in London, in tube stations. We did speak to everyone who was anyone here, wondering if Asoka could go to the Oscars. But the one that got chosen was Lagaan: Once Upon a Time in India (2001) which was even better. So we had no complaints. After that I didn't make any film for the foreign market."

Introduction

In the current Internet scenario, various classic applications run on multiple networks. These applications could have been written using different languages like Visual Basic, Visual C++. For example, a retail organization would have different systems, such as an inventory management system, a bill of material systems, and a general ledger system, all implemented using various technologies available for application development. These systems need to be integrated to form a higher-level enterprise information system for an organization. To do so, application developers had to use technologies such as Microsoft Distributed Component Object Model (DCOM), Component Object Model and so on. However, these distributed technologies are very tightly coupled to the programming languages in which these applications have been developed. This leads to problems in application integration if the applications have been developed using disparate technologies.

Developers who have developed applications using Microsoft technologies have extensively used Component Object Model (COM) technology to develop components. These components were used mainly to encapsulate the business logic of the application. COM technology suffered from the following limitations:

Registration of COM components.
Unloading COM components.
Data link library (DLL) hell.

Microsoft .NET has been developed keeping the above limitations in mind and making Web services development one of its major goals.

Automatic Memory Management.

To provide a very high degree of language interoperability
To provide a runtime environment that completely manages code execution
To provide a very simple software deployment and versioning model
To provide high-level code security through code access security and strong type checking
To provide a consistent object-oriented programming model
To facilitate application communication by using industry standards such as SOAP and XML.
To simplify Web application development

Proposed Solution:

Interoperability

The interoperability features of .NET allow you to work with existing unmanaged code (that is, code running outside the CLR) in COM components as well as Microsoft Win32 DLLs. It also allows you to use managed components from your unmanaged, COM-based code. These features allow you to choose if and when to migrate existing unmanaged code to .NET.

The various types of interoperability supported by .NET

Calling a COM component from .NET - When a COM object is called from .NET, the runtime generates a runtime callable wrapper (RCW). The RCW acts as a proxy for the unmanaged object.

The RCW is responsible for handling all interaction between the .NET client code and the COM component, including (but not limited to):

Creating and binding to the underlying COM object.
Consuming COM interfaces and factoring the interfaces into a managed form.
Translating and marshaling data between environments.
Managing the lifetime of the wrapped COM object.
Translating COM HRESULT values into .NET exceptions

Calling a .NET component from COM.

When a .NET component is called from COM, the runtime again generates a wrapper object to bridge the gap between the environments. In this case, the runtime generates a COM callable wrapper (CCW). The runtime reads the type information for the component from its assembly metadata and generates a compatible CCW. Similar to the RCW, the CCW acts as a proxy between the unmanaged COM code and the managed .NET code.

Calling unmanaged application program interface (API) functions from .NET.

This interoperability, called Platform Invocation (commonly abbreviated as P/Invoke), allows managed code to call into C-language-style API functions, handles the marshaling of data types between managed and unmanaged types, finds and invokes the correct function in the DLL, and facilitates the transition from managed to unmanaged code.

A good example of P/Invoke functionality is calling one of the many Win32 API functions exposed by the Windows operating system. Through P/Invoke functionality, the runtime also supports callbacks from API functions. The current release of .NET, however, does not support calling from a Win32 DLL into .NET managed code. To call directly from unmanaged code to managed code, you must use COM interoperability.

Migration

Once you decide to migrate part or all of an existing application to .NET, you will need to decide how best to approach the migration. There are two major approaches to migration i.e. horizontal and vertical. Horizontal migration involves replacing a whole tier of your application. For example, you may choose to replace the ASP code within your Web-based presentation tier, or you may replace the COM code within your middle tier as the initial migration step. Vertical migration involves isolating and replacing a piece of your application through all n tiers.

Guidelines

Choose a migration strategy that minimizes the risk of migration.
Choose migration activities that allow you to continue to use your existing COM code base as you move to .NET.
Quickly take advantage of the new features provided by the .NET environment.

Horizontal Migration - In a horizontal migration, you migrate an entire tier of your Windows DNA-based application to .NET without immediately migrating the other tiers. By migrating a single tier at a time, you can take advantage of the features of the .NET Framework specific to a particular tier (for example, ASP .NET on the presentation tier), in many cases without modifying application code or affecting operations on another application tier.

Choosing a horizontal migration strategy

The first step in a horizontal migration is to decide which tier to migrate first.

To replace the Web tier, you replace ASP code with code developed using ASP .NET. You may also externally expose much of your middle-tier functionality with .NET Web services. Ideally, the Web tier can be replaced with few or no changes to the middle tier. If you migrate your Web tier to ASP .NET you can make use of the following features:

Advanced data binding functionality
Easier configuration management
Improved session state management
Advanced caching capabilities
Easy development of Web services
Compiled code, which results in better performance
The Web Forms programming model with server-side event handling
Server-side controls, which make it easier to develop solutions targeting multiple browsers

To replace the middle tier, you migrate your middle-tier COM components to .NET with few or no changes to the Web tier.

In deciding whether a horizontal migration strategy is appropriate, and if so, which tier is the most appropriate for initial migration, consider whether your existing Windows DNA-based solution has the following characteristics:

Large number of Web servers
Shared code migration
Heavy use of ASP Application or Session state
Complex middle tier

Vertical Migration - Another migration approach is to migrate a portion of your application vertically through all application tiers. This essentially involves carving out a piece of your application that has minimal interaction with other pieces and migrating it. This includes both ASP code and COM components. An example might be converting the search functionality of your Web site to .NET, including the presentation tier, business tier, and data tier. The remaining functionality of the site is left in traditional COM and ASP until the time is right for migration to .NET, based on your project schedules, resources, and current system architecture. Any remaining interfaces between the new managed code and the unmanaged code function through COM interoperability.

Choosing a vertical migration strategy

You might choose to adopt a vertical migration strategy for a number of reasons:

Good application isolation - If parts of your application are well isolated from other parts of your application, you have an excellent candidate for vertical migration. Parts of an application that are well isolated share very little state information with the rest of the application and can easily be migrated with little impact on the rest of the system.
Adding new functionality to an existing application - when adding new functionality to an existing application, you should strongly consider using the .NET Framework to develop the new functionality.
Heavy use of ADO recordsets between tiers - many applications pass disconnected ADO record sets from the data and business tiers to the presentation tier. They then iterate through the record sets and generate HTML tables. This type of application is well suited to a vertical migration.
Planning to re-architect - If you plan to re-architect your application, vertically migrating part of your application to the new architecture provides a good test bed for the new design. The .NET Framework also makes it easier to provide the functionality that newer architectures are built on.

Vertical migration considerations

Before undertaking a vertical migration, you must consider the following issues:

Application-slicing for a vertical migration
Migration of shared code
Session and application state management in a mixed ASP/ASP .NET environment
Interaction between ASP and ASP .NET code in a mixed ASP/ASP .NET environment
Interoperability and translation of managed and unmanaged data types
CLR deployment
Application deployment
Configuration of COM+ based applications and .NET Enterprise Serviced Components
Optionally using Application Center 2000 to ease deployment

Interoperability vs. Migration

The first thing to consider in terms of a migration is whether to migrate the code at all. The COM interoperability features of the .NET Framework are very powerful and, in nearly all cases, allow you to continue to use your existing code without migrating it to managed code. As you develop new parts of your application or reuse components of your application from newer managed code applications, in most cases you can simply call your existing components through the COM interoperability functionality provided by .NET. Interoperability allows you to preserve the investment that you have already made in developing and stabilizing the code, familiarizing developers with it

Performance

Overall, the overhead of calling from managed code to unmanaged code through COM interoperability is minimal. If your method performs any substantial tasks, it is likely that the overhead from the interoperability layer will be a negligible percentage of the overall method call time. However, if your method does nothing more than set a value for a property or perform some other small task, the overhead of the interoperability layer may be a significant portion of the method call. If your interface is made up of a number of these property sets and gets, known as a chatty interface, the interoperability cost may be unacceptably high.

Enhancing Development Productivity

The .NET development environment provides significant improvements to the COM-based development model for distributed applications and can significantly enhance developer productivity. If your application is expected to undergo a number of changes and development cycles in the future, you should consider migrating the application to take advantage of the higher developer productivity inherent in the .NET development platform.

Using a Managed Object Model

If most clients of your existing components will be written in managed code, you should consider either migrating your component to managed code. Your managed code clients will expect your component to look and act like a managed object. Although the RCW makes the component look somewhat like a managed component, it does not change the underlying interfaces to the component. When developing against your unmanaged component through COM interoperability, managed code developers will not be able to use parameterized constructors, static methods, inheritance, and other features they are accustomed to working with in managed code. Migrating your component or writing a managed wrapper will make your component easier to use for managed code developers.

Taking Advantage of .NET Features

In some cases, you will want to migrate parts of your application to .NET so that you can take advantage of the new features that the .NET Framework offers. For example, ASP .NET provides advanced data binding, browser-dependent user interface generation, and improved configuration and deployment. You should evaluate when the value of bringing these new features to your application outweigh the cost of code migration.

Implementation Details:

As an application developer you can face some issues as you develop your migration and interoperability plan.

- Choosing which pieces of your application to migrate
- Migration to and interoperating with ASP .NET

Choosing Pieces of Your Application To Migrate

Choosing the right pieces of your existing application to migrate is an essential task in ensuring a successful vertical migration. It is recommended that you perform a code path analysis on your current application.

Code path analysis

A typical Windows DNA-based application consists of one or more ASP pages with which a user interacts. Those ASP pages call one or more COM components, which in turn may call additional COM components. The COM components eventually access a database and either store data or retrieve data on behalf of the user. The ASP pages and components that are used during the user's single interaction would be considered a code path.

In many cases, the objects used in a code path neither depend on nor access other components in the application. Distinct code paths are a natural place to consider isolating a piece of your application for migration to .NET. Code path analysis of the application typically results in discovering pieces of your application with minimal interaction with other parts of the application, thereby minimizing interoperability needs. You can use code paths to help identify which pieces of an application are suited to vertical migration.

Interoperability for shared components

An analysis of your Web site in terms of the code paths is likely to identify components that are shared among multiple code paths. In a vertical migration, these components can be accessed through the COM interoperability functionality until all the code paths that interact with the component have been migrated. Code paths that share components between them are good candidates for migrating concurrently, minimizing the COM interoperability required.

ASP .NET Migration Guidelines

Migration guidelines specific to migration from ASP to ASP .NET and interoperating between the two environments.

Avoid or replace the ASP session object

You cannot share session state across a mixed ASP/ASP .NET environment using the intrinsic Session object. In a vertical migration, the best way to avoid this problem is to not use the intrinsic Session object in your ASP application. Numerous methods exist for working around server-based session storage and allowing information to be passed from page to page. All these methods work with both ASP and ASP .NET:

Using cookies
Using hidden form fields
Encoding session information in URL strings (URL munging)
Manually storing and retrieving session information from the database through direct ADO (from ASP) and ADO .NET(from ASP .NET) calls
Using a custom session object that stores state in a database (This method is discussed in the following section.)

If your application does not already make heavy use of the Session object, you should generally use one of the first three methods in the previous list, all of which avoid sharing session state on the server.

Sharing state using a database

The ASP .NET Session object has the ability to store session data in a Microsoft SQL Server database automatically. However, you cannot access this data from ASP (it is stored in a binary format, which is not easily read) without considerable work and custom code on the ASP side. You also cannot directly instantiate the ASP .NET Session object through COM interoperability and use it to retrieve the session state. So, abstracting the storage and retrieval of session information away from the ASP/ASP .NET layer involves replacing the use of the built-in session object with a custom implementation for storing session state.

Any replacement used for the Session object should follow the dictionary pattern adopted by the intrinsic session objects, and should be capable of storing and retrieving named value pairs, for example:

mysessionobject("somekey") = "somevalue"

By adopting this pattern, you can replace the intrinsic session object in your existing ASP code quickly and easily. When the remaining parts of your application are converted to .NET, you can easily replace the custom implementation with the native ASP .NET session object.

Remember that if you use a custom session object (written as a COM object), each call to the object from ASP .NET will go through the COM interoperability layer, so you should try to minimize the amount of interaction you have with the session state object. Another option is to simply have separate code in each environment that reads and writes session information to the same external database.

Avoid or replace the application object

In a vertical migration, application state (in addition to session state) cannot be directly shared between the two environments using the intrinsic Application objects. Typically, the majority of information stored in application state is either data or objects that are expensive to create for each page, and is created and initialized in the Application_OnStart event in the application's global.asa file.

The simplest method for dealing with this issue is to recreate the data and objects in both environments. This allows you to maintain your existing ASP application environment and also take advantage of the equivalent and enhanced ASP .NET features such as improved caching, tracing, and deployment. This approach works well if the data is fairly static; however, if you change the data frequently, you will need to do additional work to keep the data synchronized between the environments. If you do not want to store the data in both ASP and ASP .NET, or if you change the data frequently, you will need to find an external place to store it that is accessible from both environments such as a SQL Server database.

Use Response.Redirect

You cannot use Server.Transfer and Server.Execute between ASP and ASP .NET pages. For interactions between the two environments, use Response.Redirect instead.

Security

ASP .NET does not enable impersonation by default. If you use impersonation within the presentation tier to enable role-based security in the middle tier, you must explicitly enable impersonation in ASP .NET. The impersonate attribute of the identity tag in your web.config file should be set to true. For example:
