I'm trying to load a C# class into a Messenger Live Script, but the Debuuger sais it can't create the object.

code:

---

var source = new ActiveXObject('SourceServer.Protocols.Source');

---

The C# is just a normal C# Class library project, but I've checked the checkbox 'Register class for COM' at the build properties page.

What am I doing wrong, or is there any other way to load it?
