Live-share: LiveShare seems to break the debugger

[AnthonyMastrean]

Describe what happened:

I can't start a debugger session (or whatever) unless I disable the plugin.

You may only use the Microsoft .NET Core Debugger (vsdbg) with
Visual Studio Code, Visual Studio or Visual Studio for Mac software
to help you develop and test your applications.

The library hostfxr.dll was found, but loading it from c:\Users\anthony\AppData\Roaming\Code\User\globalStorage\ms-vsliveshare.vsliveshare\dotnet-3.1.1\host\fxr\3.1.1\hostfxr.dll failed

The target process exited without raising a CoreCLR started event. Ensure that the target process is configured to use .NET Core. This may be expected if the target process did not run on .NET Core.
The program '[28676] testhost.exe' has exited with code -2147450750 (0x80008082).

Me too. Disabling the extension allowed debugging to work.

Is there any update on this issue? LiveShare is pretty prominent feature of VS and vscode and it kind of sucks to have to keep it disabled.

@divinebovine, @AnthonyMastrean, @atruskie: thanks for reporting the issue! This should be fixed in our latest Live Share update available in the VS Code Marketplace (v 1.0.2236). If you can test your repro on the latest extension and confirm it is resolved it would be much appreciated.

@jramsay looks like its working for me! Thank you!

[jramsay]

@divinebovine: thanks for confirming! Will close out this issue.
