WCF在向客户端发送响应之前抛出

Question

I have a WCF service where IGameServices contains:

[ServiceContract]
public interface IGameServices
{
    [OperationContract]
    DtoReturnedMessage<DtoGame> GetGame(Guid gameId);
}

AdminServices contains:

public class AdminService : IGameServices
{
    private readonly BoGame _boGame = new BoGame();

    public DtoReturnedMessage<DtoGame> GetGame(Guid gameId)
    {
        return _boGame.Get(gameId);
    }
}

I have that BoGame, which is a class with business logics.

My config is:

 <system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IGameServices" sendTimeout="00:05:00" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:50380/Services/Implementations/AdminService.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IGameServices"
            contract="IGameServices" name="BasicHttpBinding_IGameServices" />
    </client>
</system.serviceModel>

When I debug it step-by-step, all the business logics works properly, and throws the exception below when the response should be sent to the client.

An error occurred while receiving the HTTP response to http://localhost:50380/Services/Implementations/AdminService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

It is weird because I have a method to save some data into the DB, in the same IGameServices, which saves normally and returns the success message as expected.

Does any one know what that can be?

Answer 1

I solved the problem. The error was too generic, actually. The issue was with build versions of Postsharp not matching.

I found it out by trying to open the services directly on the browser. I removed Postsharp in that project and BANG.
