Finalizers should be protected







Breaking Change


A public type implements a finalizer that does not specify family (protected) access.

Finalizers must use the family access modifier. This rule is enforced by the C#, Visual Basic, and Visual C++ compilers.

To fix a violation of this rule, change the finalizer to be family-accessible.

Do not exclude a warning from this rule.

This rule cannot be violated in any high-level .NET language; it can be violated if you are writing Microsoft Intermediate Language.
