"This cheat sheet lists more advanced tools, toolkits and controls beyond the standard Mango SDK 7.1, such as NuGet, Silverlight Toolkit, MVVM Light, Catel, Phone7.Fx, Coding4Fun and others."
Just FYI, I'm kind of sick of playing the "7.1 vs 7.5 version numbering" game so going forward when referring to anything Mango I'm just going to call it 7.1(5)
Anyway... Here's some snips of the 2 page PDF cheat sheet.
