title: xUnit + VS2015, does group by Traits work?
body: <p>I'm using xUnit with VS2015. Some codes are decorated by [Trait("Category", "C1")]. However, in the test explorer, it always shows 'no traits' when using group by traits. I tried to put the decoration at both class and method level.</p>
  
  <p>I searched. It seems it was a bug in year 2015: <a href="https://stackoverflow.com/questions/32258618/visual-studio-2015-test-explorer-does-not-see-xunit-dnx-traits">Visual Studio 2015 Test Explorer does not see XUnit dnx traits</a></p>
  
  <p>Is this fixed now? Does it work for anyone? or, still a bug? Anyone can confirm this?
  xUnit: 2.1.0
  VS: 14.0.25123.00 update 2.
  .Net 4.6.01055</p>
  
  <p>Thanks.</p>
