How Do I get my VB.NET DLL functions to show up in VBA Object Browser?

I recently coded a VB.NET class in Visual Studio 2010 which has a bunch of public functions in them.  I compiled the DLL and referenced it in Excel VBA.  I can see the class name in the object browser, and I can see a public structure I have in the DLL, but none of the functions in the class are visible in the object browser.

What's funny is that I can create an instance of the class and call the functions, but none of the functions show up in Intellisense.  How can I get those functions to show up in the object browser?  Is this an issue of late vs. early binding?

You have to decorate your class with the following attribute:

    [ClassInterface(ClassInterfaceType.None)]

That definitely helped.  The other missing component was to create an interface for my class.  When I did that, I could see all of the functions in the Object Browser.

Thanks!

The solution was half of what I needed.  It was necessary to decorate my class, but I also need to implement an Interface to show the various functions in the object browser.
