[Mono-devel-list] mcs not recognizing FlagsAttribute?

[Marek Safar]

Hi,
I can confirm it is mcs bug, please fill a bug report. If you need 
workaround move enums out of the FlagsAttributeDemo class.

>I compiled the following sample MSDN library code for the FlagsAttribute class and ran with mono to find that the output was not as expected.  It is the same with/without the FlagsAttribute specified.  A monodis of the compiled code doesn't show any reference to the attribute.
