…#19231) Extend the pattern match in ConstraintSolver.fs to also reject FSMeth when it represents a static abstract interface member being called directly on the interface type. The check handles FSMeth case alongside ILMeth: - Not a constrained call via type parameter - Not an instance member (i.e., static) - Is on an interface type - Is a dispatch slot member (abstract) Uses the same error message 3866 (chkStaticAbstractInterfaceMembers).
