    you don't have to remove it, try to install previous version. Debugging with C# Dev Kit 'v0.2.100' works in mine

    When will MSFT finally not release crappy releases? My productivity goes down due to bad quality of this c# dev kit.

    It even caused me to not have a certain job due to VS being updated just before the interview, and all intellisense was gone.
