I have successfully used the WPRUI and WPA applications in the past, the last time a month ago, to identify performance problems in our C++ applications. But today I recorded a new trace of one of them, and open it just to see WPA crashing. It's reproducible every time by opening an ETL and going to Graph Explorer -> Computation -> CPU Usage (sampled) -> unfold. Just clicking to see the CPU sampled graph list. Sometimes it crashes silently, sometimes with the dialog that lets you debug the crash. Has anybody experienced problems like this? I don't see any support forum in the Windows Performance Toolkit site, and I would like of course to find a solution for this. Any hints are greatly appreciated, thanks in advance.
PS: reinstalling doesn't help. Neither does removing user preferences. The stack only showed me a problem accessing memory out of bounds, in a "Task" class, but I can't get the debug dialog to show again (it's crashing silently now, every time).
PS2: the only significant change I remember to have done in this past month is installing the CTP of Visual Studio 2015, and letting Windows upgrade a bunch of packages it had pending (I'm in a capped subnetwork and Windows doesn't upgrade automatically).
The VS2015 CTP installs a .Net 4.6 pre-release version. Maybe this .net versions causes the issue. So remove VS2015 CTP and the .Net 4.6 Preview and reinstall .Net 4.5.2.
