Configuration of webservice client

I've created proxy classes using svcutil with a given "SAP CRM" WSDL file. It worked great and it generated a output.cs.

So added this output.cs in my visual studio project und created a simple test application. The test application can be compiled and even run, but I don't know why. I didn't enter any service URL.

How can this be and how can I configure the test application to use the proper SAP URL?

Thanks

it's a follow up question to this Problem creating proxy class with wsdl.exe

You'll have following constructors in your generated proxy:

 public SampleServiceClient(string endpointConfigurationName)
        :
            base(endpointConfigurationName)
    {
    }

public SampleServiceClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress)
    :
        base(binding, remoteAddress)
    {
    }

The first one references endpoint description in your config file, the other accepts programmatically created binding and endpoint address.

As for username/password part, with your binding properly configured, use the proxy.ClientCredentials.UserName property.
