title: Blazor: Failed to launch debug adapter
body: <p>kind of desperate with this problem that I don't know how to fix and I don't know the cause.
  Full error when running Blazor app:</p>

  <p>It's a WASM application hosted in .net core. Therefore there is a backend and a frontend.
  I have set my backend project as Startup project, which will take care of hosting also the frontend.
  Both projects are set up on .NET 5.
  I have read that multiple factors can cause this error and yet I tried all the possible solutions I have found so far.</p>
  <ul>
  <li><p>I kill manually the app processes that hang running even when I stop debugging, closed VS, deleted the whole .vs folder and then restarted VS.</p>
  </li>
  <li><p>I disabled script debugging<br />

  </li>
  <li><p>Also tried enabled and disabled:<br />

  </li>
  <li><p>Tried also to start it with latest version of Microsoft Edge instead of Chrome, sometimes it works and doesn't give troubles sometimes it doesn't</p>
  </li>
  <li><p>in a post I have read from the official support that it's a bug that is being solved already in the 16.10 VS preview version. I downloaded and installed it, still nothing.</p>
  </li>
  <li><p>tried both iisExpress and .net CLI as hosting profile.</p>
  </li>
  </ul>
  <p>Moreover when starting the app a normal blank page only opens on the browser:</p>
