Concurrency Profiler on Visual Studio 2012 was moved
I wanted to run a concurrency profiling on my app so I activated the performance wizard and chose the last option (concurrency) but the results where nothing like I expected. The report I got looked similar to the sampling report presenting information about contention.

I looked around and found that the good old concurrency profiling is now called “Concurrency Visualizer”.
Click it and you’ll get all the concurrency reports.

Enjoy
