WCF Configuration Hell?

Question

I hate WCF setup with endpoints, behaviors etc. I believe all these things should be performed automatically. All I want to do is to return JSON result from my WCF service. Here

Answer 1

Take a look at this SO question.

Edit: Since you're not specifying an address for your service, try hitting: http://localhost:22059/ZombieService.svc/KnownZombies (with the .svc).

I also think you need the <webHttp /> behavior added to your specified endpoint behavior.

Edit: Try changing your endpoint definition to this:

<service 
  name="HighOnCodingWebApps.ZombieService"
  behaviorConfiguration="MyServiceTypeBehaviors">

  <endpoint 
    address="" 
    binding="webHttpBinding"
    behaviorConfiguration="SomeBehavior"
    bindingConfiguration="default"
    contract="HighOnCodingWebApps.IZombieService" />

</service>

Answer 2

In your WebGet or WebInvoke Specify your BodyStyle to WrappedRequest, then remove the UriTemplate. When Invoking your service use the function name.

Hope it helps.

Example:

    [OperationContract]
    [WebInvoke(Method = "POST",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json)]
    void register(string name, string surname);

Answer 3

You are using the WebInvokeAttribute which tells WCF by default to accept POST as the verb. Since you are trying to access it via a GET action, it is being ignored.

Use WebGetAttribute instead.

Per MSDN:

If you want a service operation to respond to GET, use the WebGetAttribute instead.

Answer 4

Have you tried the WCF SvcConfigEditor? It is available from the Tools menu in Visual Studio. Open your web/app.config with SvcConfigEditor to get GUI help on getting everything right.

Answer 5

I am using .net framework 4, VS2010. I made a dummy mistake in my global.asax.cs that instead of creating an instance of WebServiceHostFactory I punched WebScriptServiceHostFactory through intellSense. As a result I got the same error:

Endpoints using 'UriTemplate' cannot be used with 'System.ServiceModel.Description.WebScriptEnablingBehavior'.

I corrected the instance to WebServiceHostFactory in my global.asax.cs, I don't see the error anymore.

Answer 6

Just use ASP.NET Web API instead of WCF
