at MiniValidation.MiniValidator.TryValidate[TTarget](TTarget target, IDictionary`2& errors) in /_/src/MiniValidation/MiniValidator.cs:line 59The issue is that the compiler generates a type representing the anonymous function that breaks validation.
There is a workaround, adding the SkipRecursion attribute, but in my case, the type I want to validate is declared in a separate library, which I have no access to, so I have to skip validation of the whole type. So it would be great if MiniValidation would support this out of the box.
