Question

I’m getting this strange error when I try connect to my WCF with webHttpBinding service from a web browser:

Sendera:ActionNotSupportedThe message with Action ” cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

My app.config:

<services>
  <service name="MyNamespace.MyService">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:9091/MyService/" />
      </baseAddresses>
    </host>
    <endpoint address="" binding="webHttpBinding" contract="MyNamespace.IMyService" />
  </service>
</services>

My method simply looks like this:

[WebGet(UriTemplate = "foo/{id}")]
public string GetFoo(string id)
{ ...

OK – I would expect you’re probably missing the endpoint behavior needed – try this config:

<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>    
<services>
  <service name="MyNamespace.MyService">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:9091/MyService/" />
      </baseAddresses>
    </host>
    <endpoint 
        address="" 
        behaviorConfiguration="web"
        binding="webHttpBinding" 
        contract="MyNamespace.IMyService" />
  </service>
</services>
