Can't build project referencing self-built FCS and FSharp.Core package

[auduchinok]

I'm trying to upgrade FCS in the Rider plugin. However, there are issues with building.

Due to #17698 FSharp.Core is no longer referenced as a package, and is referenced as a project instead. We build FCS ourselves but I don't know a way to build FSharp.Core properly, so its assembly strong name matches the one published by Microsoft. Is there something that I miss and it's possible? If not, then we need to find a way to use FSharp.Core package when building FCS.

As a workaround I've tried to use both 8.0.400 and the current preview FSharp.Core versions, but I'm getting an error during build:

Error CS0115 :
  'FsShim.OpenFileForReadShim(string, FSharpOption<bool>, FSharpOption<bool>)':
  no suitable method found to override

It seems there may be some issue in the code generated by F# compiler?
Here's a minimized repro:

I don't think this will ever work.

I think the only way now is to wait for rc2, update it here, and it should allow using package version of fsharp.core. Or try downgrading to p6 and use 8.0.400

Thanks! Do you know if there're any estimates when it's going to be available?

@auduchinok --- working on it now, How did I not know nested generic types required this, although it makes perfect sense to me now.

Unfortunately no, it's already frozen for a week, so I expect it to be available soon
