WCF REST call returns "Method not allowed" exception

I am trying to create a WCF Restful Service.

Here is my contract: (The ActivateUser class extends the BaseResult class).

namespace SmartShopServerContract {
[ServiceContract]
public interface IService {
    [OperationContract]
    [WebGet(RequestFormat=WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json, UriTemplate="au/{eMail}/{password}/{idHandy}")]
    ActivateUserResult ActivateUser(string eMail, string password, string idHandy);
}

// Basisklasse der Resultate --> alle Resultate haben einen definierten Status!
[DataContract]
public abstract class BaseResult {

    private string status;

    public BaseResult(string status) {
        this.status = status;   
    }

    [DataMember]
    public string Status {
        get { return this.status; } 
    }
}

// Result für ActivateUser
[DataContract]
public class ActivateUserResult : BaseResult {
    public ActivateUserResult(string status)
        : base(status) {
    }

    [DataMember]
    public string CryptedPassword { get; set; }
}

}

Here is the implementation of the Service:

namespace SmartShopServerService {
public class ServiceSmartShop : IService {

    public ActivateUserResult ActivateUser(string eMail, string password, string idHandy) {
        return new ActivateUserResult("OK") {
            CryptedPassword="testatsa"
        };
    }

And there is the Web.config file:

    <?xml version="1.0"?>
<configuration>
  <system.serviceModel>
     <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint helpEnabled="true" automaticFormatSelectionEnabled="false" defaultOutgoingResponseFormat="Json">
        </standardEndpoint>
      </webHttpEndpoint>
    </standardEndpoints>
    <services>
      <service name="SmartShopServerService.ServiceSmartShop" behaviorConfiguration="RESTBehavior">
        <endpoint address="/" binding="webHttpBinding" contract="SmartShopServerContract.IService" behaviorConfiguration="SmartShopBehavior"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="RESTBehavior">
          <serviceMetadata httpGetEnabled="true" policyVersion="Policy15"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="SmartShopBehavior">
          <webHttp automaticFormatSelectionEnabled="false"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.5" sku=".NETFramework,Version=v4.5"/>
  </startup>
  <system.web>
    <compilation debug="true"/>
  </system.web>
  <system.webServer>
    <modules>
      <remove name="WebDAVModule"/>
    </modules>
  </system.webServer>
</configuration>

I am testing this with the "VS2012 native tool commant prompt" like this:

svcutil.exe http://localhost:51162/SmartShopService.svc/au/data1/data2/data3

The code is being executed, but I am still getting a Method not allowed (405) exception.

Any thoughts on that?

--> currently local use

--> IIS Express (Visual Studio 2012)

The problem was the base class (BaseResult) for the ActivateUser class --> BaseResult

It seems like that it is not possible to extend a DataContract class and expect it to work.

Now i am using a Interface instead of a base class

public interface IResult {
    string Status{get;set;}
}


[DataContract]
public class ActivateUserResult : IResult {

    [DataMember]
    public string CryptedPassword { get; set; }

    [DataMember]
    public string Status { get; set; }
}

This is working....thats all i know ;)

You're using svcutil to create a proxy for a "RESTful WCF service". This does not work. The quick reason is that Web endpoints do not expose metadata for the svcutil tool to know what requests it needs to send to it. The long version is on the linked blog post.
