It looks like Microsoft.Dynamic was updated to use something that is only available in 4.5. I'm looking in ReflectionUtils.cs at the following code:
private static bool IncludeMethod(MethodInfo member, Type reflectedType, HashSet<MethodInfo> baseDefinitions, bool flattenHierarchy) { if (member.IsVirtual) { if (baseDefinitions.Add(RuntimeReflectionExtensions.GetRuntimeBaseDefinition(member))) { return true; } } else if (member.DeclaringType == reflectedType) { return true; } else if (!member.IsPrivate && (!member.IsStatic || flattenHierarchy)) { return true; } return false; } Looking at RuntimeReflectionExtensions on MSDN it says its only supported in 4.5? slide -- Website: http://earl-of-code.com _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org http://mail.python.org/mailman/listinfo/ironpython-users
