title: MSBuild Issue for jenkins build step System account
body: <p>I'm trying to build UWP project, project builds correctly if i run the script from command line myself. if i use the same script in jenkins it fails with this error,i searched a lot to find the solution and someone suggested to use <code>NUGET_PACKAGES=C:\NugetPackageCache</code> but that didn't help either.
  I'm still getting the error below </p>
  
  <blockquote>
    <p>(ResolveNuGetPackageAssets target) -> 
             C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Microsoft\NuGet\15.0\Microsoft.NuGet.targets(186,5):
    error : The package Microsoft.CSharp with version 4.0.1 could not be
    found in C:\Windows\system32\config\systemprofile.nuget\packages</p>
