Thank you for the replies. Now, I recompiled Python.Net with .Net 4.0 and get below working with simple AAA.BBB.Adapter after reading
http://stackoverflow.com/questions/14520888/clr-addreferenceexample-file-unable-to-find-assembly?rq=1 http://stackoverflow.com/questions/13259617/python-for-net-unable-to-find-assembly-error?rq=1 http://sourceforge.net/p/pythonnet/bugs/17/ http://sourceforge.net/p/pythonnet/bugs/18/ Now I have below sample code(Adapter.proj has two c# files), and experimented Class1.cs ----------- namespace AAA.BBB.CCC { public class Adapter { public string Function1() { return "AAA.BBB.CCC: Adapter Function1 Called"; } public void Function2() { Console.WriteLine("AAA.BBB.CCC: Adapter Function2"); } } public class Network { public string Function1() { return "AAA.BBB.CCC: Network Function1 called"; } public void Function2() { Console.WriteLine("AAA.BBB.CCC: Network Function2"); } } } namespace AAA.BBB { public class Adapter { public string Function1() { return "AAA.BBB: Adapter Function1 Called"; } public void Function2() { Console.WriteLine("AAA.BBB: Adapter Function2"); } } public class Network { public string Function1() { return "AAA.BBB: Network Function1 called"; } public void Function2() { Console.WriteLine("AAA.BBB: Network Function2"); } } } Class2.cs ----------- namespace AAA.CCC { public class Adapter { public string Function1() { return "AAA.CCC: Adapter Function1 Called"; } public void Function2() { Console.WriteLine("AAA.CCC: Adapter Function2"); } } } Then, I got below. It seems working great.

I don't know how to specify different namespace of class when creating an instance. 2. The class that I already have has similar above layout in a project. Common project has many class files in it, and each class has different name space and class name. AddReference('Common') looks working and loaded, but can't import. >>> clr.AddReference('Common') <System.Reflection.RuntimeAssembly object at 0x052E73C8> >>> from Network import * Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named Network >>> from Network.Common import * Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named Network.Common >>> Difference is that Common project has [Serializable] and enabled "Make assembly COM-Visible" [Serializable] [Description("SimpleDictionary")] public class SimpleDictionary : ISimpleDictionary { ... } Any thoughts? Wonder if there is a way to list available class after AddReference(). Thanks, Spark. On Thu, Apr 18, 2013 at 9:14 PM, Stephen P.
