Boxing COM objects... how does VB.NET resolve it?

[urielk]

I added to my project refernces an AciveX control, the enviroment created the wrapper as expected.

But when I try to use it, the compiler requires to cast the objects, example:

MyActiveXObj myObj = (MyActiveXObj)TheControl.MyObj;

but it fails at run time with invalid casting exception.

To test it I switched to Visual Basic.Net and it works without problem, the following line compiles and executes just fine:

Dim myObj as MyActiveXObj
myObj = TheControl.MyObj

What I am doing wrong in C# ?

There was an article in Visual Studio magazine this month about .NET and COM interoperability.

Sorry I couldn't be of more help.
