Using VSTools for Addin-Programming
 

Hi

I am a little bit confused and unfortunately there is not much documentation on msdn.microsoft.com

I would like to add an Excel-AddIn for Excel 2003 on basic of an existing .NET application (.NET 1.1)
Do do I have to use (or is it even possible) Visual Studio Tools or just Visual Studio .net 2003 with interop-assemblies?

Thanks in advance for your answers!!

Greeting
Stefan
