As the screenshot below illustrates, if you start with a virtual method void M<T>(T? t) and generate an override for it in some other type, the generated override doesn't have any type parameter constraints, but that results in compilation errors.
We should generate a where T : default constraint, which tells the compiler that T? in the override doesn't mean System.Nullable<T>.
