Thanks for reporting, this is a perfect issue! Never worry about creating issues, no issue is worse than duplicate issue or poor issue.

Sorry about the bug and the slow fix.

As long as it's fixed, thanks a lot!

I think 0.2.0.1-dev is not semver compatible version, 0.2.0-dev1 would be better.

@sungam3r does it break nuget.exe so the package should be republished with correct version? I can republish and unlist if so, only takes seconds.

I have installed the package from VS 2019. Maybe some other clients might have problems, I don't know.
