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

[jpease at twcny.rr.com]

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.

I'm using the most recent Fedora Core 1 rpms.  Has anyone else had similar problems, or is there something I'm missing?  The example appears to be OK...

// Example of the FlagsAttribute attribute.
using System;

class FlagsAttributeDemo
{
    // Define an Enum without FlagsAttribute.
    enum SingleHue : short
    {
        Black = 0,
        Red = 1,
        Green = 2,
        Blue = 4
    };

    // Define an Enum with FlagsAttribute.
    [FlagsAttribute] 
    enum MultiHue : short
    {
        Black = 0,
        Red = 1,
        Green = 2,
        Blue = 4
    };

    static void Main( )
    {
        Console.WriteLine( 
            "This example of the FlagsAttribute attribute \n" +
            "generates the following output." );
        Console.WriteLine( 
            "\nAll possible combinations of values of an \n" +
            "Enum without FlagsAttribute:\n" );
        
        // Display all possible combinations of values.
        for( int val = 0; val <= 8; val++ )
            Console.WriteLine( "{0,3} - {1}", 
                val, ( (SingleHue)val ).ToString( ) );

        Console.WriteLine( 
            "\nAll possible combinations of values of an \n" +
            "Enum with FlagsAttribute:\n" );
        
        // Display all possible combinations of values.
        // Also display an invalid value.
        for( int val = 0; val <= 8; val++ )
            Console.WriteLine( "{0,3} - {1}", 
                val, ( (MultiHue)val ).ToString( ) );
    } 
}
