Will VSTO add-ins developed for Office 2007 work in Office 2010?

Question

Are the VSTO add-ins that were developed for Office 2007 compatible with Office 2010? If not, what would need to be done to upgrade them to run in 2010?

Answer 1

According to this (german) blog nothing big will change:

So I think it is save to say that it will work (althoug I would recommend to upgrade the code due mayor improvements in VSTO.NE(X)T).

Answer 2

Yes, as stated here.
