title: Why can't Visual Studio find this nuget package's .props file?
body: <p>Due to some git project changes, when I try to build, I get an error:</p>
  <blockquote>
  <p>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see <a href="http://go.microsoft.com/fwlink/?LinkID=322105" rel="nofollow noreferrer">http://go.microsoft.com/fwlink/?LinkID=322105</a>. The missing file is ..\packages\MSTest.TestAdapter.1.1.11\build\net45\MSTest.TestAdapter.props.</p>
  </blockquote>
  <p>The references to the project contain four missing references, two of which <code>Microsoft.VisualStudio.TestPlatform.TestFramework</code>, and <code>Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions</code> which seem to be related.</p>
  <p>The other two, in case it proves to be relevant are <code>System</code>, and <code>System.Core</code>, but they aren't causing any problems... which is weird, cause I'm definately using them.</p>
  <p>That missing file, the one from the error message, is absolutely there.</p>
  <p>I've tried to uninstall and reinstall both packages, but nothing seems to help.</p>
