excel .NET Addin in c#

[Frank M. Walter]

Hi @ALL,

this topic is not new, but I have not found any solution.

I have make an .NET c# Interop-assembly with UDF.

Adding an UDF to worksheet, I can not see in Inputbox
neither function description nor help link.
The comments are "not available"

How do I put within addin-dll description and help link
to function wizard?

Any c# snipped will be welcome.

Thanks

Frank
