Again, this was a 4 hours project. It isn’t fancy. It was done quickly after a long trip and little sleep so please don’t hold me accountable for not covering all the best practices in ASP.Net MVC, not properly referencing all the JavaScript libraries, not documenting the code, not making it fully mobile friendly, not testing it with FireFox, etc. (I’m sure you will find many other points)
Lots of folks at Microsoft are stepping in to help and soon a much better site will be taking over this, so this code is just for your reference and to prove the point of how simple the whole thing is.
Enjoy
