Index out of range when building with shipped compiler

[vzarytovskii]

While working on building FCS with shipped compiler, I'm getting the following error for dotnet build FSharp.Compiler.Service.sln in CI:

error FS0193 : internal error : Index was outside the bounds of the array. [C:\projekty\fsharp\dotnet-build\src\FSharp.Compiler.Interactive.Settings\FSharp.Compiler.Interactive.Settings.fsproj::TargetFramework=netstandard2.0]

Which may indicate, that a shipped compiler in 7.0.201 has some bug.

I have seen this issue regularly lately.

This occasionally happens in some of my projects too. Actually I never saw it in a real compile, but VS tooling sometimes reports it.

I never saw it in rider yet, if that helps.

This should've been fixed in latest versions of fcs. I think. So if you see it again, please report with versions of tooling
