Hello,

use the version from GitHub https://github.com/pythonnet/pythonnet

Starting with the 4.5.X runtime there are types which do not have a namespace. Hence the original code which uses the namespace of a type

      internal static void Register(Type t) {

            Dictionary<string, List<string>> nsmap = null;

            mapping.TryGetValue(t.Namespace, out nsmap);

will throw an ArgumentNullException. This code is corrected in the github version:

      internal static void Register(Type t) {

            if (null == t.Namespace || null == t.Name)

                return;

            Regards

                        Stefan

Is this the problem with Windows Server 2012 R2 (or .NET 4.5.1) ?

Can I download somewhere Python.Runtime DLL where this problem is fixed ?
