I have asked this elsewhere, but have never found anyone knows how to build an add-in for VBA IDE using VB.NET. Is it even possible? Could someone point me to an example?
Also take care that the Guid of the project (in case of c# in assamblyInfo.cs) is different from the Guid of the Class "Connect".
Having the same Guid results in a "could not be converted to a type library"-error when checking: Project Properties > Build Tab > Register for COM Interop
