title: Cannot debug project after upgrading to Service Fabric SDK v2.3.301
body: <p>Recently upgraded to Service Fabric SDK v2.3.301, but for some reason my project got corrupted. I cannot debug the project, I get the following error: "A project with an Output Type of Class Library cannot be started."</p>
  
  <p>It seems that the solution now fails to recognize the Service Fabric App. Yet I am able to deploy to my local cluster. </p>
  
  <p>Anyone had similar issues while upgrading to the new SDK?</p>
  
  <p>Thanks  </p>
  
  <p>PS Just in case, the service fabric app is the already set as startup project :o)</p>
