Non-Toolbox support

[jrr]

I haven't investigated this at all yet, but I suspect the problem is that I have an individually-installed Rider, rather than using Toolbox.

I ran e.g. rider foo.sln, and got the following stack trace:

Unhandled Exception: System.ArgumentNullException: Value cannot be null.

Experienced the same issue. It looks like it's that the following file does not exist:

OK, I'll see what I can do.

Although you should totally use Toolbox :)
