Please use nuget.exe 4.1 from https://dist.nuget.org/index.html and specify MSBuildVersion 15.1, because actually msbuild version is 15.1 for VS 2017, so specifying 15 can't find msbuild

Dealing with this issue since yesterday. I actually had to uninstall previous MSBuid versions on my build server and remove the -MSBuildVersion argument from the call to get it to work with 15.1.

I cannot get this to work even if I specify 15.1 as the -MSBuildVersion.

P.S.: The agent is specified as "VS 2017". The NuGet version is specified as 4.0.0. I tried using 4.1.0 but no luck so far. There is no documentation regarding how to use "NuGet Tools Installer" task.

C:\LR\mms\Services\Mms\Provisioner\TaskAgent\agents\2.117.1\externals\nuget\NuGet.exe pack "d:\a\1\s\Src\ProjectName\ProjectName.csproj" -OutputDirectory "d:\a\1\a\Packages" -Properties Configuration=release -version 1.0.20170616 -MSBuildVersion 15.1
Cannot find the specified version of msbuild: '15.1'
System.Exception: Unexpected exit code 1 returned from tool NuGet.exe
   at Microsoft.TeamFoundation.DistributedTask.Task.Internal.InvokeToolCmdlet.ProcessRecord()
   at System.Management.Automation.CommandProcessor.ProcessRecord()

The same exception is thrown if I specify MSBuildVersion as "15" instead of "15.1".

NuGet 3.5 didn't find v15, I've downloaded latest NuGet 4.3 and had to remove -MSBuildVersion (attempts to specify 15, 15.0 or 15.1 didn't help).
Then the MS Build was found:

MSBuild auto-detection: using msbuild version '15.3.409.57025' from 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\bin'. Use option -MSBuildVersion to force nuget to use a specific version of MSBuild.

The last sentence is wrong/misleading. I confirmed that only -MSBuildVersion 15.3 is acceptable value on my machine.
