@TheAngryByrd Is there any workaround we can use to fix it at the moment?

[TheAngryByrd]

Not that I know of. I've never really used the AOT features in .NET.

[TheAngryByrd]

@vzarytovskii is this something the F# team has seen at all?

[xperiandri]

What steps would you propose? Should we provide you a minimum reproduction?

[vzarytovskii]

@vzarytovskii is this something the F# team has seen at all?

Haven't seen, no, @vitek-karas @sbomer, what would be the easiest way of figuring out why does it fail to compile? State machines is highly generic code, so I assume something related to that?

[vitek-karas]

I can't repro this (tried on windows as mac). Could you please:

• Create an issue in dotnet/runtime repo for this?
• In the issue, if you can, share the repro project
• Share the version of .NET you're using (dotnet --info)
• Share the version of VS you're using
• What target device you have set in VS when you build
• If possible share a binlog of the build

[vzarytovskii]

This needs to be over at dotnet/runtime (if it's not already).

[vitek-karas]

+1 - please create an issue in dotnet/runtime for this. Thank you!
