After upgrading to .NET 7.0, I'm getting "PositiveRecall" is not supported. Why?

[CBrauer]

My System information is:

• OS & Version: Widows 11, version 22H2
• Microsoft Visual Studio Professional 2022 (64-bit) - Version 17.4.1
• Microsoft.NET SDK 7.0.100 (x64)
• .NET Version: NET 7.0

Bug description

My program has been running fine for the last year. After upgrading to .NET 7.0 it now fails with the error:
"PositiveRecall is not supported".

Here is a screen shot of the error message:

My Visual Studio clearly shows that PositiveRecall shows is legal:

Please help.

That is very strange... what version of .NET were you using before your upgrade? Any other upgrades at the same time (like ML.NET itself)?

This issue has been marked needs-author-action and may be missing some important information.

I was using .NET 6.0.

@CBrauer did you update ML.NET versions at all? What version are you currently using?
