.NET 3.1 installation fails

When I open vscode from WSL, I get this error:

Downloading the .NET Runtime.
Downloading .NET version(s) 3.1.18 ... Error!

This is coming from .NET Install Tool for Extension Authors which Visual Studio IntelliCode Insiders depends upon.
I cannot uninstall the .NET extension because Intellicode depends on it.

dotnet/vscode-dotnet-runtime#159 is open to track this issue. I will also check if there's any solution to bypass this issue.

The new version of '.NET Install Tool for Extension Authors' has been released and it fixes issue. Let me know if you still see the issue(you might need to uninstall '.NET Install Tool for Extension Authors' to get rid of cache issue).

I uninstalled the retail Intellicode and installed IntelliCode Insiders for WSL. I got the same dotnet installation error. Interestingly, Intellicode Insiders thinks it is installed. I can hover and see examples on GitHub, so it must be installed and working. Maybe the error was left over from a previously installed extension; I'm not sure.

I tried installing on another machine. That machine received no error. So it appears that the error has been fixed.
