title: How to let xUnit runner only execute tests in specific classes?
body: <p>In my csproj file I've defined a test target which is used to execute xunit tests in a specified DLL:</p>
  
  <pre><code>&lt;UsingTask AssemblyFile="..\packages\xunit.1.9.2\lib\net20\xunit.runner.msbuild.dll"     TaskName="Xunit.Runner.MSBuild.xunit" /&gt;
    &lt;Target Name="Test"&gt;
      &lt;xunit Assembly="bin\Debug\My.Project.dll" /&gt;
  &lt;/Target&gt;
  </code></pre>
  
  <p>This works fine, however I would like to be able to specify that only tests in certain classes should be executed. Is this possible?</p>
