a destructor with 'protected private' accessibility cannot be a member of a class declared 'sealed'

A Windows Runtime class declared as sealed cannot have a protected private destructor. Only public virtual and private non-virtual destructors are allowed on sealed types. For more information, see Ref classes and structs.

To fix this error, change the accessibility of the destructor.
