title: msbuild 14 doesn't work without full .net framework installation
body: <p>I have a build machine with visual studio 2010 and multiple build targets.
  all the other targets that I use works as expected and for some reason the new build of version 14 for .net 4.6.1 doesn't work.</p>
  
  <p>When I'm executing the build from command line I get the following error:</p>
  
  <blockquote>
    <p>C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(1097,5): warning MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.6.1" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.</p>
  </blockquote>
  
  <p>Can someone explain to me how to solve it?</p>
