AutoCAD .NET :: Call COM Object From 2011?

I tried to call COM object created by C# from other C# module.

I did:

1. Create simple COM object by C#

2. Register it

3. Try to call this COM from other C# console application - it works fine

4. Create simple AutoCad module by C# with IExtensionApplication

5. Try to call this module from AutoCAD - it works

6. In Initialize() method I wrote:

Type myClassAdapterType = Type.GetTypeFromProgID("CoreAdapter.CoreAdapterClass");

 acDoc.Editor.WriteMessage("Type is OK: {0}", myClassAdapterType.FullName);

 object myClassAdapterInstance = Activator.CreateInstance(myClassAdapterType);

acDoc.Editor.WriteMessage("Created");

6. Open AutoCAD again

7. Load my module

8. I saw "Type is OK" (becase it was registered in registry)

But I can't create instance.
