I want to convert a VBA Excel add-in (xlam file) to a COM add-in, written in C# and using Add-in Express (although this might not be relevant). The VBA add-in has several internal sheets that are used for various operations - for example a base for creating template sheets (see screenshot). Is there any way to have this kind of sheets in a COM add-in? If not, which would be the best approach to have some template sheets? Thank you for your time!

Found the answer in this thread: Store and open a Workbook in VSTO as "resource" The idea is to add the template workbook to the project and setup, so it gets extracted with all other add-in files. Then use the sheets from there.
