you have a .NET c# app that launces/connects to Excel through (OLE)

No, my addin is loaded when excel starts. What I'm trying to do is to cast a
COMAddIn object retrieved from Excel.Application.COMAddIns collection to my
add-in type for further use.

As an example, here's the code from my .net app:

object myComAddIn = comAddIn.GetType().InvokeMember("Object",
BindingFlags.Public | BindingFlags.GetProperty,
null, comAddIn, null);

myComAddIn.GetType().InvokeMember("Test",
BindingFlags.Public | BindingFlags.InvokeMethod,
null, myComAddIn, null);

The above code successfully invokes the Test() method of my COM AddIn. What
I'm trying to do next is to cast myComAddIn to my com add-in type, which
fails.

The reason is to be able to subscribe to add-in's custom events. Any ideas?
