title: Is there anyway to set up automated build task in Team Services for ".xproj" .NET Core project
body: <p>I my team and I are using Visual Studio 2015, Team Services to build and manage a .NET Core application with multiple .NET Core class libraries all of which are ".xproj" projects. We are now looking to move away from manual builds and follow the continious integration and deployment approach. When adding a build task in Team Services there is a template option for building .NET Core applications. When selected I can see that the restore and build jobs are auto populated with the .csproj extension. </p>

  <p>I have changed these to xproj and ran a build only to get the following error for each project in the solution.</p>
  
  <p>Test.xproj'. The file type was not recognized.

  Any help is appreciated.</p>
  
  <p>Thank you.</p>
