TypeConverter converter = TypeDescriptor.GetConverter(typeof(T))

where T is uint fails on IL2CPP ?

System.MissingMethodException: Constructor on type ‘System.ComponentModel.UInt32Converter’ not found.

Is this a BUG or just a feature of IL2CPP ?

It looks like it was fixed a couple of years ago:

Which version is you using, and what platform are you building for?

3

2019.4.26f1 - android il2cpp arm64

Perhaps just to file another bug report then. Not sure how much support it’s on 2019 though.
