  WCF client fails to run "Getting Started" code with Multiple Endpoints

  Feb 27, 2012 12:45 PM|LINK

  I start a new instance instance of the service (In Debugger) in VS 2010 and ASP.NET Development Server starts and launches the service at:   http://localhost:57705/Calculator.svc  (I can see it in Internet Explorer) and it seems fine.   Note: I cannot browse to this location in IE: http://localhost/servicemodelsamples/service.svc  (it is not clear if I should be able to browse here)   However when I start a new instance of the client (In Debugger) in VS 2010 I receive an exception at this line:   double result = client.Add(value1, value2);

  Exception: ********** "InvalidOperationException was unhandled" Could not find default endpoint element that references contract 'ICalculator' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

  HI,

  Looks like you’re using the Calculate sample from SDK.

  Have you modified anything?

  Try to compare your code with the original sample.

  In particular, check if the namespace is correct. In config file, the namespace is Microsoft.ServiceModel.Samples.

  But the generated code doesn’t seem to have a namespace.

  Try to wrap everything in that generated file in the Microsoft.ServiceModel.Samples namespace.

  Re: WCF client fails to run "Getting Started" code with Multiple Endpoints

  Thanks very much for your reply.  I was trying to modify the original GettingStarted tutorial but have now just copied the sample code from the GettingStarted-MultipleEndpoints sample code as the code was changed quite a bit.  Please see revised code below.

  When I start the instance of the service I see the service web page in IE at URI: http://localhost:57705/service.svc

  I receive an error when running the following line of code in the client.cs file:  

      double result = client.Add(value1, value2);

  Error "EndpointNotFoundException was unhandled". There was no endpoint listening at http://localhost/servicemodelsamples/service.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
