The information in part 2 of Threading in the Windows Runtime deals with the internals of the threading model. This section, originally presented by Marytn Lovell at Build 2013, is intended to be trivia or possible useful in debugging, but not necessary for day to day development. For more practical information, please refer to part one of InfoQ’s key points summary.

In a session titled Diving deep into C++ /CX and WinRT, Marian Luparu talks about exception handling and performance for C++ applications that target Windows 8. The most important thing for developers to understand is how the boundary between WinRT and normal C++ code effect exception handling and performance.
