See Roslyn-Detected C# Warning Classes for more information.
'Enum.HasFlag' method expects the 'enum' argument to be of the same 'enum' type as the instance on which the method is invoked and that this 'enum' is marked with 'System.FlagsAttribute'. If these are different 'enum' types, an unhandled exception will be thrown at runtime. If the 'enum' type is not marked with 'System.FlagsAttribute' the call will always return 'false' at runtime.
This check corresponds to Roslyn rule CA2248. For full rule details, see the Microsoft website: CA2248.
