If the server can't create the object then it is not registered with COM. You must strong name the server object, put it in the gac, and register it with COM using regasm. Please look at my article on the topic, I'm pretty sure it will help you.

You need a COM callable wrapper (CCW) in your C# dll. Then it becomes accessible from javascript or vbscript. See my article on the topic.

Best,

yes, it is

reference...

using System.Runtime.InteropServices;
//after the namepace name
[ComVisible(true), ProgId("YourClass.Application")]

just do a....in vbscript or asp

set objMydll = CreateObject("YourClass.Application")
