Ok, got my MSDN subscription again, so posting with this account I should
get a response?
BTW, I asked the mono developers and it works fine with gmcs. Only .NET has
this problem.

I thought GetInterfaceMap should work for every interface returned by
GetInterfaces()... but here I have a counterexample. Has anyone seen this
before? Here's a unit test for Zanebug (substitute your favorite test
runner):
using Adapdev.UnitTest;
[TestFixture]
class GetInterfaceMap
{
[Test]
public static void ByteArray()
{
System.Type baseType = typeof(System.Byte[]);
foreach (System.Type iface in baseType.GetInterfaces())
{
System.Diagnostics.Trace.WriteLine(iface.FullName);
Assert.IsNotNull(baseType.GetInterfaceMap(iface));
}
}
}
It fails for GetInterfaces()[4/5/6], which are the instantiated generic
interfaces, IList<Byte>, ICollection<Byte>, and IEnumerable<Byte>. Is
this a bug, or is it documented somewhere that it should work this way?
