title: xUnit doesn't write message to the output pane
body: <p>In Visual Studio 2015 Community I have a sample ASP.NET 5 (vNext) project and a project with unit tests (xUnit.net). The version of DNX is 1.0.0-beta5. My goal is to add messages during the test run to the output pane.
  <a href="http://xunit.github.io/docs/capturing-output.html" rel="noreferrer">Here</a> I took a way to do this, so my unit test code looks like this:</p>
  <pre class="lang-cs prettyprint-override"><code>using Xunit;
  using Xunit.Abstractions;
  
  namespace UnitTests
  {
  
      public class UnitTest1
      {
          ITestOutputHelper output;
  
          public UnitTest1(ITestOutputHelper output)
          {
              this.output = output;
          }
  
          [Fact]
          public void TestTestTest()
          {
              output.WriteLine(&quot;Test Message&quot;);
              Assert.Equal(2, 2);
          }
  
      }
  }
  </code></pre>
  <p>Visual Studio Test Explorer discovers this test (and that's OK), but all I have in the <em>Output</em> pane (from Tests) is:</p>
  <pre><code>------ Run test started ------
  ------ Test started: Project: UnitTests ------
  Starting  Microsoft.Framework.TestHost [C:\Users\*******\.dnx\runtimes\dnx-clr-win-x86.1.0.0-beta5\bin\dnx.exe --appbase &quot;C:\Users\*******\Documents\Visual Studio 2015\Projects\MvcMovie\UnitTests&quot; Microsoft.Framework.ApplicationHost --port 55837 Microsoft.Framework.TestHost --port 55893]
  Connected to Microsoft.Framework.TestHost
  Running tests in 'C:\Users\*******\Documents\Visual Studio 2015\Projects\MvcMovie\UnitTests\project.json'
  ========== Run test finished: 1 run (0:00:03,2267169) ==========
  </code></pre>
  <p>Also, there is not any link &quot;Output&quot; under the selected test run information, like here:
  <a href="https://i.stack.imgur.com/XvJxe.png" rel="noreferrer"><img src="https://i.stack.imgur.com/XvJxe.png" alt="Enter image description here" /></a>
  (Only &quot;Test passed... Elapsed time ...&quot;)</p>
  <p>What should I do to make this <code>ITestOutputHelper</code> work?</p>
