I believe this started to happen after reinstalling Unity. Seems like for some reason the extension doesn't see the .NETFramework 4.7.1. But the .NET installer says that 4.7.1 or never is already installed.

The .csproj and .sln files:
Assembly-CSharp.zip

@TiredOfCoding How did you download .NET? Did you download the 4.7.1 "Developer Pack" from https://www.microsoft.com/net/download/visual-studio-sdks ?

[alkaitagi]

Was downloading Dev Pack from https://www.microsoft.com/net/download . Downloaded from your link and installation proceeded and the issue resolved. Thank you!

[heaversm]

Where is the developer pack for Mac? Only appears listed for PC as an .exe file.

[rchande]

@heaversm You need to install mono (https://www.mono-project.com/download/stable/#download-mac). I recommend installing version 5.18 from that page instead of using homebrew/etc package managers.

@TiredOfCoding How did you download .NET? Did you download the 4.7.1 "Developer Pack" from https://www.microsoft.com/net/download/visual-studio-sdks ?

Installing this developer pack solved my issue. Also, THIS guide was helpful.
Earlier I tried to install .NET Framework 4.7.2 but it didn't help.
