+The following code throws an exception on mono, but works on MS.NET 2.0:
+
+-- snip --
+
+using System;
+using System.Reflection;
+
+public class test
+{
+        public static void Main ()
+        {
+                Assembly asm = Assembly.Load ("System, Version=2.0.0.0,
+Culture=neutral, PublicKeyToken=b77a5c561934e089");
+                Type blah = asm.GetType
+("System.CodeDom.Compiler.CodeDomProvider");
+
+                foreach (Attribute a in blah.GetCustomAttributes (false)) {
+                        foreach (PropertyInfo f in
+a.GetType().GetProperties (BindingFlags.Public|BindingFlags.Instance)) {
+                                Console.WriteLine (f.GetValue (a, null));
+                        }
+                }
+        }
