[Mono-list] about guid

Are you talking about the algorithms for and implementation of Type.GUID, or are 
you talking about the algorithms for and implementation of UUID / GUID 
generation in general?  Why wouldn't an RFC4122-compliant implementation would 
not be acceptable?

You can manually apply a GuidAttribute to these classes, something
like that:

using System;
using System.Runtime.InteropServices;

[Guid("7ADF8247-2749-447E-890C-47BC7B42999F")]
class Program
{
    static void Main ()
    {
        Console.WriteLine (typeof(Program).GUID);
    }
}


Automatic Type.GUIDs are not implemented in Mono, mostly
because the algorithms behind MS' implementation are not well
documented.
