Hosting Silverlight in C++

I'm a bit over my head here and would like some advice on how to go about.

Basicly what I want to do is to be able to render and control silverlight inside my C++ application. I would like something as:

class silverlight_host
{    
public: 
     // Prio 1
     silverlight_host(const std::string& filename); // Load a xap file       
     void draw(void* dest); // Draw with alpha to dest
     std::pair<size_t, size_t> get_size(); // Need to know required size of dest

     // Prio 2
     bool is_dirty() const; // Check for dirty rect since last call to draw
     void send_param(const std::string& param); // Send data to silverlight control or call functions. Alternative name maybe, call_function
     void set_size(size_t width, size_t height); // Set the size of drawing.  

     // Prio 3
     // Some more nice to have functions, although not as important as those above
     double get_desired_frame_rate(); // The desired frame rate which is specified in xap
     std::pair<size_t, size_t> get_desired_size(); // The desired size which is specified in xap
     void tick(); // Tick a synchronous timeline, disable internal asynchronous timer
     void set_param_callback(const std::function<void(const std::string&)>& callback); // Let the xap file call the application
};

Easier said than done. I have found the following articles Host Silverlight Contorl in C++ and Communication between C++ Silverlight Host and Silverlight Application. My problem with these are that the provided code doesn't seem to work when compiled in VS2010 and they create an actual window instead of a windowless control. Also what happens is not very well explained and I am somewhat lacking in COM and ATL knowledge.
