title: Fail the entire run at VS unit test even if conitinue after failure is checked
body: <p>I have a c# unit testing code at VS in which I like to fail the entire run if a specific [TestMethod] is failed, even though I have checked the "continue in case of a failure".</p>
  
  <p>--adding more detail--
  
  <pre><code>[TestMethod] \\should fail the entire run
  public void ImportentTest(){}
  
  [TestMethod] \\ should continue to the next testmethode if fail
  public void LessImportentTest(){}
  </code></pre>
