+1, the master branch merged the previous future branch recently, does that mean we need "VS15"?

[jmarolf]

@diryboy No we are all using VS 2015.2 on our end as are our build machines. This doesn't repro on my dev box. I created a fresh VM with just VS 2015.2 + VSSDK and git installed. Build succeeded.

Suggestions:

1. Run git clean -xdf to clear out any files left in your enlistment (but be careful as this blows away unstaged changes)
2. Run taskkill /IM vbcsCompiler.exe /F and taskkill /IM msbuild.exe /F to kill these processes and ensure they are not holding on to old dlls.
3. Delete your nuget cache (located under C:\Users\%USERNAME%.nuget)

If these steps don't help, well need to dig a bit deeper. We shouldn't be able to put you in a state where msbuild can't find mscorlib.

git clean -xdf fix it for me. Thanks.

[diryboy]

git clean -xdf also worked for me, thanks @jmarolf!
