title: VS for Mac 2019 - tests won't run
body: <p>Set up a toy project in Visual Studio for Mac 2019 to try it out.
  I created a new xUnit project with a single test... </p>
  
  <pre><code>public class UnitTest1
  {
      [Fact]
      public void Test1()
      {
          Assert.True(true);
      }
  }
  </code></pre>
  
  <p>When i try to run this test I get the following error:</p>
  
  <pre><code>Running LMS.LMS.Tests.LMS.Tests.UnitTest1.Test1 ...
  Result message:
  One or more errors occurred. (vstest.console failed to connect.) 
  (vstest.console failed to connect.)
  </code></pre>
  
  <p>I installed nuget package xunit.runner.console but no change.</p>
  
  <p>Has anyone any thoughts for this issue?</p>
