Error building samples

Hello,

I am just getting started with the ProjectWise SDK, so I figured that the samples were a good first stop.  I opened the .sln file in Visual Studio 2015, but when I build the solution, I get two build errors.  Both of them say "MSB6006 "cmd.exe" exited with code 9009".  The first error is with the project "admext" and the second error is with the project "dsctest".  Is there something special that I need to do to build these two projects?  Any special build instructions that I am overlooking in the help document?  Any guidance that you can offer would be extremely appreciated.  Also, is there a single place in the documentation where all of the samples are discussed/summarized, or are they just referred to throughout the documentation?  Thank you.

Jon
