Hi Calvin, I am brand new to this, so am not sure I can help, but I am also developing in a Microsoft .Net environment. My application has a number of components (Web App, Winforms Desktop app, as well as class libraries). I've been working my way through the documentation I've found on this site and others, and trying to adapt the predominantly PHP examples to my .NET environment. So far I've had success both reading data from Canvas (HTTP GET) as well as writing data to Canvas (HTTP POST). I'm not sure what you're after specifically, but I am interested in meeting anyone else who is integrating Canvas with a .NET platform. So, if you're still looking for an answer on this, let's chat.
