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 is my configuration:

<system.serviceModel>
<bindings>
  <webHttpBinding>
    <binding name="default"/>
  </webHttpBinding>
</bindings>
<services>
  <service name="HighOnCodingWebApps.ZombieService"
     behaviorConfiguration="MyServiceTypeBehaviors">
    <endpoint address="" binding="webHttpBinding"
      bindingConfiguration="default"
      contract="HighOnCodingWebApps.IZombieService"
      behaviorConfiguration="webScriptEnablingBehavior"/>
  </service>
</services>

<behaviors>
  <endpointBehaviors>
    <behavior name="webScriptEnablingBehavior">
      <enableWebScript/>
    </behavior>
  </endpointBehaviors>

  <serviceBehaviors>
    <behavior name="MyServiceTypeBehaviors">
      <serviceMetadata httpGetEnabled="true"/>


    </behavior>
  </serviceBehaviors>
</behaviors>

<serviceHostingEnvironment aspNetCompatibilityEnabled="false"/>

And I have the following service implementation:

public class ZombieService : IZombieService
    {
        [WebInvoke(Method = "GET",
                    ResponseFormat = WebMessageFormat.Json,
                    UriTemplate = "KnownZombies")]
        public Zombie GetZombie()
        {
           return new Zombie() { Name = "Mohammad Azam"};
        }
    }

    public class Zombie
    {
        public string Name { get; set; }
    }

When I visit http://localhost:22059/ZombieService/KnownZombies says the following message:

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

If I remove the WebScriptEnablingBehavior from the web.config I get the following error:

The message with To
‘http://localhost:22059/ZombieService.svc/KnownZombies’ cannot be
processed at the receiver, due to an AddressFilter mismatch at the
EndpointDispatcher. Check that the sender and receiver’s
EndpointAddresses agree.

UPDATE 1:

I updated the configuration to this:

 <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="default"/>
      </webHttpBinding>
    </bindings>
    <services>
      <service name="HighOnCodingWebApps.ZombieService"
         behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint address="http://localhost:22059/ZombieService.svc" binding="webHttpBinding"
          bindingConfiguration="default"
          contract="HighOnCodingWebApps.IZombieService"
          />
      </service>
    </services>

    <behaviors>
      <endpointBehaviors>
        <behavior name="SomeBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="MyServiceTypeBehaviors">

          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

  </system.serviceModel>

Now when I visit http://localhost:22059/ZombieService.svc/KnownZombies I get the following message in the browser:

The message with To
‘http://localhost:22059/ZombieService.svc/KnownZombies’ cannot be
processed at the receiver, due to an AddressFilter mismatch at the
EndpointDispatcher. Check that the sender and receiver’s
EndpointAddresses agree.

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>
