Question

I have a WCF Service that exposes two endpoints. One with a WebHttpBinding (acting as a REST service for mobile clients) and one with a NetTcpBinding (used for desktop .NET clients)

Let’s say that a client accesses the service method GetData. If there is no data I will return ´null´ (or false or ´0´ depending on what has been called). If the client is a mobile client accessing the WebHttpBinding-endpoint, I would like to change the HttpStatusCode to something other than OK.

Is there a way of doing this and still keeping my service implementation general (not putting any http-specific code there)? I know that I can use IDispatchMessageInspector to intercept the message and change the status code, and only do this for the WebHttpBinding-endpoint, but then I wouldn’t really know what to change the status code to…

Is there anyone who has a suggestion as to how I can solve this?

Update:

I’m starting to think that there really is no way to do this in a nice way, since the only place I actually really know what when wrong is in the service implementation.

Edit: the nice way: Seperation of concerns (SoC). The REST implementation only adds REST concerns to the service and inherits the base implementation which does the whole business logic.
