nuget.exe restore fails with Visual Studio 2015 toolset

[jozefizso]

Details about Problem

NuGet product used: NuGet.exe

NuGet version: 4.0.0.2275

VS version: Visual Studio 2015 Professional, Update 3

OS version (i.e. win10 v1607 (14393.321)): win10-pro v1607 (14393.693)

Detailed repro steps so we can see the same problem

1. Clone NuGetGallery from https://github.com/NuGet/NuGetGallery
2. Checkout tag v2017.02.24
3. Run .\build.cmd
4. Build will run nuget.exe restore C:\dev\github\NuGetGallery\NuGetGallery.sln -MSBuildVersion 14 command
5. This will fail with error Cannot find the specified version of msbuild: '14'

Other suggested things

NuGet Docs says that -MSBuildVersion supports values 4, 12, 14 and 15. I have Visual Studio 2015 installed so NuGet should work with version 14.

Workarround: using version '14.0' will use the correct MSBuild toolset, eg. nuget.exe restore C:\dev\github\NuGetGallery\NuGetGallery.sln -MSBuildVersion 14.0
