I have a versioning issue with a WCF service contract in which one of the many endpoints which are called for the operation is missing one method from the contract.

My question is, how can I make sure the command is available on the client before attempting to call it?

I tried:

  foreach (var od in proxy.Endpoint.Contract.Operations)
  {
    if (od.Name == "MyMethodName")
    {
      hasMethod = true;
      break;
    }
  }

Unfortunately, this is using the contract from the calling app and does not actually describe the implementations on the endpoint itself. As a result, it returns true even though the endpoint has failed to implement the command.
