Numerous instances of VBCSCompiler.exe

Question

I just recently downloaded and installed Visual Studio Professional 2015 (14.0.23107.0). The first time I opened up our solution (28 projects) and performed a Build -> Rebui

According to Slaks, you can disable roslyn (which is what the VBCSCompiler.exe appears to be) by setting the DisableRoslyn environment variable to true.

See http://blog.slaks.net/2014-05-21/exploring-roslyn-part-2-inside-end-user-preview/ for more information.

Note, the link above is for the preview, but I can't imagine that it would have changed much between then and now.
