Something is messed up with c# scripts

Latest WIP

  1. Object reference not set to an instance of an object.

Error building script: Could not find a part of the path ‘C:\Program Files\dotnet\shared\Microsoft.NETCore.App\9.0.14\Microsoft.CSharp.dll’.

I can’t reproduce that here. Side note: If I search for that dll I get 134 matches.
It’s unclear to me what ‘part of the path’ means.

That is an error message I get from Isopod. Weirdly the components which were already in the definition all executed. I’ll close Rhino and start again. The problem has vanished.

This just happened again after duplicating an Isopod component. Going to restart Rhino…

Problem disppeared.
