title: Cannot see local variables when opening an App Services Debug Snapshot
body: <p>I just spent some time configuring a test .NET Core 2 Web App with Debug Snapshots according to <a href="https://docs.microsoft.com/en-us/azure/application-insights/app-insights-snapshot-debugger" rel="nofollow noreferrer">this doc from MS</a></p>
  
  <p>I works quite well and I am able to open the snapshot through the portal, however it displays this error for all the local variables:</p>
  
  <p>"Cannot obtain value of the local variable or argument because it is not available at this instruction pointer, possibly because it has been optimized away."</p>
  
  <p>I already installed the latest Application Insights site extension into the Web App, restarted the App (just in case) and I can see it in the Extensions panel, however I still cannot see the vars through the portal - what am I missing?</p>
  
  <p>Thanks in advance</p>
