    copied!<p><strong>UPDATE:</strong> I don't know if this helps anyone diagnose this issue but the wsdl has the end point as:</p> <pre><code>http://localhost:8523/Temp/WebService.svc/WebService.svc </code></pre> <p>Which is wrong, I've tried manually changing the endpoint to remove the extra bit at the end and it still returns a 404</p> <p><strong>/Update</strong></p> <p>I'm working on a web service using WCF, when I run the VS2010 debugger I get the following error message:</p> <blockquote> <p>The target assembly contains no service types. You may need to adjust the Code Access Security policy of this assembly.</p> </blockquote> <p>The solutions to this I've found online say that I should add [ServiceContract] to the interface but it's already there.</p> <p>I've also seen people say that I have to delete the tag from the csproj file but doing this makes the project a class library rather than a web service.</p> <p>But my browser opens to a directory listing and I can navigate to the wsdl generated by the container by clicking on the .svc file and then clicking on the link to .svc?wsdl </p> <p>If I try and hit the service from an application or from the WCF Service Tester I get an exception with a 404, I cbbled together a test app and here is the exception it gives me:</p> <pre><code>Sending Message: Make Call: InteractionId [rt], Destination [ert], ExternalReferenceId [ert], userIdentifier [ert] attachedData [rt] System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at http://localhost:8523/WebService.svc?wsdl that could accept the message.
