title: TeamCity build fails without windows kits reference in proj file
body: <p>I'm having an issue on teamcity (9.1.7). I don't have visual studio installed on the build server. I have installed visual studio test agents and msbuild tools. Building one of the project fails with this error-</p>
  
  <pre><code>C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\AppxPackage\Microsoft.AppXPackage.Targets(694, 9): error APPX1639: File 'Windows.props' not found. See http://go.microsoft.com/fwlink/?prd=12395&amp;pver=1.0&amp;plcid=0x409&amp;ar=MSDN&amp;sar=PlatformMultiTargeting&amp;o1=Portable&amp;o2=7.0 for more information
  </code></pre>
  
  <p>The link doesn't work. After looking up the error, it seems i need to install Windows Kits and I need to add this to my csproj file under the first property group - </p>
  
  <pre><code>&lt;_WindowsKitBinPath&gt;C:\Program Files (x86)\Windows Kits\8.1\bin\x86&lt;/_WindowsKitBinPath&gt;
  &lt;_WindowsPhoneKitBinPath&gt;C:\Program Files (x86)\Windows Phone Kits\8.1\bin&lt;/_WindowsPhoneKitBinPath&gt;
  &lt;MakePriExeFullPath&gt;$(_WindowsKitBinPath)\makepri.exe&lt;/MakePriExeFullPath&gt;
  &lt;MakeAppxExeFullPath&gt;$(_WindowsKitBinPath)\makeappx.exe&lt;/MakeAppxExeFullPath&gt;
  &lt;SignAppxPackageExeFullPath&gt;$(_WindowsKitBinPath)\signtool.exe&lt;/SignAppxPackageExeFullPath&gt;
  &lt;MakePriExtensionPath&gt;$(_WindowsPhoneKitBinPath)\x86\MrmEnvironmentExtDl.dll&lt;/MakePriExtensionPath&gt;
  &lt;MakePriExtensionPath_x64&gt;$(_WindowsPhoneKitBinPath)\x64\MrmEnvironmentExtDl.dll&lt;/MakePriExtensionPath_x64&gt;

  <p>I really don't want to add this to my csproj file. I don't know why it is required/what impact it has. Can someone explain to me why this is needed? When i build my solution locally with visual studio, it works fine.</p>
