Following Cyaga's initial steps - I thought I'd contribute and build a C# library to access the Community Platform API.
I will continue to update the library as changes occur to the API and as we get access to other areas of the platform (characters,etc)
You can find the code at https://github.com/briandek/WowDotNetAPI
Please feel free to jump in and push changes where you see fit. Any feedback is more than welcome :)
