So, it looks like System->Frame->Card->Channel. All these are represented as objects, and there is a Parent-Child relationship ...

Rather than have the client manage various threads, I want to just fire an async method and get the result from a callback. It looks straight forward enough - just call the async method in the proxy class generated by visual studio. BUT WAIT... ther...
