Hi!

I do not feel like there is any specific place where Microsoft defines a minimum for how long Visual Studio Tools for Office (VSTO) is going to be supported, just for reference.

I need this knowledge in relation to a customer who are using VSTO and specific the library Interop.Excel from VSTO, and is not really able to change to anything else without having to go with a completely new solution for their business.

Thank you in advance!
