The model validation attributes MaxLength/MinLength are incompatible with native-aot

[sudoudaisuke]

I am using System.ComponentModel.DataAnnotations.MaxLengthAttribute for request model validation. However, MaxLengthAttribute is incompatible with native-aot (IL2026). How can I validate my model?
I found a validation option that supports source generation, but not for asp.net.

Hello,
have you considered using the [StringLength] attribute or creating a custom validation attribute?

Thank you for your response.
I use [StringLength] for strings, but not for arrays.
OpenApi schema has minItems and maxItems for arrays. I want to use MaxLengthAttribute for OpenApi maxItems.
