I was able to get rid of the errors that are shown in the activity log by doing the following:
- I have deinstalled .NET Core SDK 1.0.0 (x64) Installer (x64)
- Repaired Visual Studio
- Restarted Windows
- Installed .NET desktop environment (via visual studio installer)
Now all errors in the activity log are gone, but Visual studio is still not working. It is still showing the same error as before:
There was an error activating the remote language server, c#/Visual Basic Language Server client.
Now I have the following warnings in my activity log (these havn't been there before):
Request for "Microsoft.VisualStudio.Shell.Internal.SettingsManager (1.0)" from Process denied because the service is only exposed RemoteExclusiveClient, LiveShareGuest.
Request for proxy to "Microsoft.VisualStudio.Shell.Internal.SettingsManager (1.0)" is declined: ServiceAudienceMismatch.
Then I removed Visual Studio 2019 and installed Microsoft Visual Studio Community 2019 Preview 3.0. Now everything is up and running again. Please be aware that it wasn't enough to install the preview in parallel to the old version. The old version had to be removed first, before the error disappeared.
