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

Yes, as stated here.

Showbread

agreed, ribbon is still there, and while deprecated nothing ever really gets removed from the major object models. – Monadism

@Otaku but how about the other way around? I mean, will my Excel 2010 add-in work in Excel 2007? – Ennoble

@woodykiddy: yes, it's certainly doable from VSTO 2010, provided you target .NET 4.0. See this article: blogs.msdn.com/b/vsto/archive/2010/06/04/… – Showbread

Answer 2

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 3

I think VSTO 3.0 will not. Developed with VSTO 4.0 can.
