Is your feature request related to a problem? Please describe.

I am trying to do use validation attributes on a record that is also used as a controller model but model binding fails with a rather cryptic error, "'Foo' has validation metadata defined on property 'Bar' that will be ignored. 'Bar' is a parameter in the record primary constructor and validation metadata must be associated with the constructor parameter."

(this has already been reported in issue #30650 but it has since been closed)

Describe the solution you'd like

ASP.NET MVC should allow me to use records that have validation attributes on properties as models.
