Project configuration

Visual Studio 2015 is building forever when Parallel Build is enabled. I cannot simulate it with new or small project and attached (App3.zip) is the project configuration.

Using process monitor, I can see that the Visual Studio are repeating the steps:

Can you please provide a dump with full heap of the devenv.exe process? This should help us investigate what may be causing VS to hang.

Parallel Builds is not full supported now. 

Moving the bug to Android for visibility from the right team.
Thanks for reporting!
