[Mono-dev] typeof(Byte[]).GetInterfacesMap

Would someone please be so kind as to run the following unit test on Mono?  It's written against Zanebug but should be easy to run with any testing framework.

using Adapdev.UnitTest;

class GetInterfaceMap
    public static void ByteArray()
        System.Type baseType = typeof(System.Byte[]);
        foreach (System.Type iface in baseType.GetInterfaces())

If it fails on Mono, can someone explain why?  If it succeeds, I'm off to tell Microsoft their .NET 2.0 runtime isn't worth the hard disk space to hold it....

I'm asking because Microsoft fails miserably for GetInterfaces()[4/5/6] which are IList<Byte>, ICollection<Byte>, and IEnumerable<Byte>:
