How to: Use the ChannelFactory

.NET Framework 3.0

The generic ChannelFactory class is used in advanced scenarios that require the creation of a channel factory that can be used to create more than one channel.

To create and use the ChannelFactory class

Build and run an Windows Communication Foundation (WCF) service. For more information, see Designing and Implementing Services, Configuring Windows Communication Foundation Services, and Hosting Windows Communication Foundation Services.
Use the ServiceModel Metadata Utility Tool (Svcutil.exe) to generate the contract (interface) for the client.
In the client code, use the ChannelFactory class to create multiple endpoint listeners.

Example

using System;
using System.ServiceModel;

// This code generated by svcutil.exe.
[ServiceContract()]
interface IMath
{
    [OperationContract()]
     double Add(double A, double B);
}

public class Math : IMath
{
    public double Add(double A, double B) 
    {
        return A + B;
    }
}

public sealed class Test
{
    static void Main()
    {
        // Code not shown.
    }

    public void Run()
    {
        // This code is written by an application developer.
        // Create a channel factory.
        BasicHttpBinding myBinding = new BasicHttpBinding();
	
        EndpointAddress myEndpoint = 
        new EndpointAddress("http://localhost/MathService/Ep1");

        ChannelFactory<IMath> myChannelFactory =
        new ChannelFactory<IMath>(myBinding, myEndpoint);

        // Create a channel.
        IMath wcfClient1 = myChannelFactory.CreateChannel();
        double s = wcfClient1.Add(3, 39);
        Console.WriteLine(s.ToString());

        // Create another channel.
        IMath wcfClient2 = myChannelFactory.CreateChannel();
        s = wcfClient2.Add(15, 27);
        Console.WriteLine(s.ToString());
    }
}
