…ted. (#89998)" (#90250) This partially reverts commit 7aedd7dc754c74a49fe84ed2640e269c25414087. This change removes calls to the deprecated member functions. It does not mark the functions deprecated yet and does not disable the deprecation warning in TypeSwitch. This seems to cause problems with MSVC.
