title: Hello World sample: "Something went wrong" when installing/testing
body: <p>I tried to get the example from <a href="https://docs.microsoft.com/en-us/microsoftteams/platform/get-started/get-started-dotnet" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/microsoftteams/platform/get-started/get-started-dotnet</a> to run.
  I successfully built and published (on Azure) the webapp.
  Then I tried
   - manually editing the json file in the visual studio solution similarly to what the docs said, and then import the resulting zip in App Studio
   - adding the App directly in App Studio through the manifest editor (this works, but it fails when installing/testing it)</p>
  
  <p>Both give me an error without any more info "something went wrong".</p>
  
  <p><strong>Any way to actually figure out what I did wrong (if anything)?</strong></p>
  
  <p>Either way, maybe you guys can figure it out from the json file's contents:</p>
