title: SerializationException: Type is not resolved for member "..."
body: <p>I've been trying to dynamically load an assembly to an AppDomain. I need to do it because I want to call a method dynamically, but don't keep the handle to the DLL while my app is running, so that it can be replaced, if needed. But I'm getting this SerializationException exception: Type is not resolved for member "..."</p>
  
  <p>Here's my code:</p>
  
  <pre><code>AppDomain domain = AppDomain.CreateDomain("Temp AppDomain", null, AppDomain.CurrentDomain.SetupInformation);
  try {
      object obj = domain.CreateInstanceFromAndUnwrap(dllPath, typeName);
      IMyInterface myObj = (IMyInterface) obj;
      result = myObj.MyMethod(something);
  } 
  finally {
      AppDomain.Unload(domain);
  }
  </code></pre>
