Error installing the debugger is a preview1 version of the .NET CLI is installed

[Ethan-VisualVocal]

More of an FYI than a bug report:

It wasn't obvious to me that I needed to install an update for .NET Core to get this working. I had previously been running the Legacy C# plugin for Unity dev, but had a dotnet 1.0.0--preview1-###### build.

Solution: Go to https://www.microsoft.com/net/core#macos, follow instructions & install the latest (ended up being a preview2 for me at the time of writing this). Uninstall Legacy C# plugin, restart VSCode, install this C# plugin, restart VSCode. Success!

Error log below is what I was seeing, for others like me searching for a solution:

Thanks for the report @Ethan-VisualVocal.
@chuckries do you think we should block installing if the .NET CLI version we get back in prievew1?

[chuckries]

@gregg-miskelly sure. Just a raw dotnet --version check after we verify that it's on the path?

[gregg-miskelly]

@chuckries since we verify something is on the path by just executing dotnet I might suggest that we instead execute dotnet --version and check both that it succeeds and that the version number is >= preview2.

[chuckries]

@gregg-miskelly good call, I will take this over then.

Fixed with #715. This will be in 1.4 release.
