Hi Team,

We recently started migrating our web app from core 2.1 to 3.1, but running into below error.

We know the last and latest version of Microsoft.AspNetCore.Mvc.DataAnnotations is 2.2.0

but after migrating our app from 2.1 to 3.1, we resolved all the issues, but below issue is coming all the time...

i tried all the options... nothing working out... pls help us here and resolve this. We been trying to fix this quite long time.
