- Windows Workflow Foundation
Windows Communication Foundation
The unified programming model for rapidly building serviceoriented applications on the Windows platform
Unification
Unifies today’s distributed technology stacks
Appropriate for use on-machine, cross
machine, and cross Internet
Service
Orientation
• Codifies best practices for building distributed
applications
Integration
Interoperates with applications running on other
platforms
Integrates with our own distributed stacks

public interface IHello

string Hello(string name);
}
public class HelloService : IHello
{
public string Hello(string name)
{
return “Hello, ” + name;
}
}

Service Hosting
Self-host
class HelloHost
{
static void Main(string[] args)
{
ServiceHost host =
new ServiceHost(typeof(HelloService));
host.Open();
// Wait until done accepting connections
Console.ReadLine();
host.Close();
}
}

<%@ Service Language=“C#” Class=“HelloService” %>

Service Configuration

<configuration>
<system.serviceModel>

<service type=“HelloService"
<endpoint address=“http://localhost/HelloService"

Client Implementation
class Client

{
IHello proxy = ChannelFactory.
CreateChannel<IHello>(“HelloEndpoint”);
string r = proxy.Hello(“Omri”);
Console.WriteLine(r);
}
}

OperationContract
ties together
Message Contract,

public interface MyContract {
[OperationContract(
Action="urn:DoIt",
ReplyAction="urn:Done")]
MyReply DoIt(MyRequest request);
[OperationContract(
Action="urn:DoItAgain",

Contracts
[ServiceContract(CallbackContract =
typeof(IChat)]
public interface IChat {
[OperationContract(IsOneWay = true)]
void Chat(string text);
}
Actions control
Dispatch
[OperationContract(
Action = “Foo”,
ReplyAction = “FooResponse”)]
Message Foo(Message request);
“*” matches all
actions
[OperationContract(Action = “*”)]
void Dispatch(Message request);
22
Request/Reply and Asynchrony
One-way messages modeled using
OneWay=true operation contracts
[OperationContract(IsOneWay = true)]
void Chat(Message request);
Correlated Request/Reply modeled either as
synchronous method
[OperationContract]
Message Chat(Message request);
or using IAsyncResult pattern
[OperationContract(AsyncPattern=true)]
IAsyncResult BeginChat(Message request,
AsyncCallback cb, object state);
Message EndChat(IAsyncResult call);
