Create WCF Client without auto generated proxy

Create WCF Client without auto generated proxy

To create a WCF client without using the auto-generated proxy in C#, you can use the ChannelFactory<T> class to manually create the client and communicate with the WCF service. This approach allows you to have more control over the client code and avoid using the auto-generated proxy.

Here's an example of how you can create a WCF client without the auto-generated proxy:

  • Define the service contract and data contract interfaces:
[ServiceContract]
public interface ICalculatorService
{
    [OperationContract]
    int Add(int a, int b);
}

// Data contract for request/response
[DataContract]
public class AddRequest
{
    [DataMember]
    public int A { get; set; }

    [DataMember]
    public int B { get; set; }
}
  • Create the WCF client manually using ChannelFactory<T>:
using (var channelFactory = new ChannelFactory<ICalculatorService>("CalculatorServiceEndpoint"))
{
    ICalculatorService calculatorService = channelFactory.CreateChannel();

    // Call the service method
    int result = calculatorService.Add(5, 7);

    Console.WriteLine("Result: " + result);
}

In this example, the ChannelFactory<T> class is used to create a channel to the WCF service. The CreateChannel method is used to create an instance of the service client (ICalculatorService in this case). You need to provide the endpoint name defined in your configuration file to ChannelFactory<T>'s constructor.

You can then call the service methods on the created client object (calculatorService in this example) as if you were using the auto-generated proxy.

Remember to configure the endpoint and binding settings in your application configuration file (app.config or web.config) based on the service contract and hosting configuration.

By manually creating the WCF client using ChannelFactory<T>, you can avoid using the auto-generated proxy and have more control over the client code.

Examples

  1. "Manually create WCF client in C#"

    • Code Implementation:
      ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>("BasicHttpBinding_IServiceContract");
IServiceContract client = factory.CreateChannel();
    • Description: This code manually creates a WCF client using ChannelFactory for the specified service contract and binding configuration.

  2. "WCF client without adding service reference"

    • Code Implementation:
      BasicHttpBinding binding = new BasicHttpBinding();
EndpointAddress address = new EndpointAddress("http://example.com/Service.svc");
ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>(binding, address);
IServiceContract client = factory.CreateChannel();
    • Description: This code creates a WCF client without adding a service reference by configuring the binding and endpoint address manually.

  3. "Generate WCF client proxy dynamically"

    • Code Implementation:
      ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>(new BasicHttpBinding(), new EndpointAddress("http://example.com/Service.svc"));
IServiceContract client = factory.CreateChannel();
    • Description: This code dynamically generates a WCF client proxy using ChannelFactory with the specified binding and endpoint address.

  4. "WCF client with custom binding configuration"

    • Code Implementation:
      CustomBinding binding = new CustomBinding();
// Configure the binding elements as needed
EndpointAddress address = new EndpointAddress("http://example.com/Service.svc");
ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>(binding, address);
IServiceContract client = factory.CreateChannel();
    • Description: This code creates a WCF client with a custom binding configuration using CustomBinding and manually configuring the binding elements.

  5. "Programmatic WCF client configuration in C#"

    • Code Implementation:
      ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>();
factory.Endpoint.Address = new EndpointAddress("http://example.com/Service.svc");
factory.Endpoint.Binding = new BasicHttpBinding();
IServiceContract client = factory.CreateChannel();
    • Description: This code configures a WCF client programmatically by setting the endpoint address and binding properties directly on the ChannelFactory.

  6. "WCF client with authentication and credentials"

    • Code Implementation:
      ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>(new BasicHttpBinding(), new EndpointAddress("http://example.com/Service.svc"));
factory.Credentials.UserName.UserName = "username";
factory.Credentials.UserName.Password = "password";
IServiceContract client = factory.CreateChannel();
    • Description: This code demonstrates creating a WCF client with authentication by setting the username and password in the client credentials.

  7. "WCF client with timeout settings"

    • Code Implementation:
      ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>(new BasicHttpBinding(), new EndpointAddress("http://example.com/Service.svc"));
factory.Endpoint.Binding.SendTimeout = TimeSpan.FromSeconds(30);
factory.Endpoint.Binding.ReceiveTimeout = TimeSpan.FromSeconds(30);
IServiceContract client = factory.CreateChannel();
    • Description: This code sets timeout settings for a WCF client by configuring the SendTimeout and ReceiveTimeout properties on the binding.

  8. "WCF client with message inspectors"

    • Code Implementation:
      ChannelFactory<IServiceContract> factory = new ChannelFactory<IServiceContract>(new BasicHttpBinding(), new EndpointAddress("http://example.com/Service.svc"));
factory.Endpoint.Behaviors.Add(new CustomMessageInspector());
IServiceContract client = factory.CreateChannel();
    • Description: This code adds a custom message inspector to a WCF client by including it in the endpoint behaviors.
