Pay attention, Scott :)

Sorry. Triton is the Windows Phone 8 "Compiler in the Cloud". It basically split NGen into two pieces, allowing the optimization to happen in the Store while the .exe generation happened on the device. The interface between these two halves is MDIL.

Bing will tell you a ton about Triton.

Sorry, I see this in just one place. Sounds like an internal code name. https://www.google.com/search?q=Triton+.net+compiler
