One office plugin for both Office 2010 and 2007

Question

I've developed an office VSTO3 application for MS Office 2007. Now I'm in a process of porting it for Office 2010.

I've created a new project targeted for 2010 and mostly just copy-pasting the code from 2007 project. I've moved as much code as I can to external libraries but still there's quite much code in main project.

I was wondering if there's a better way of doing that? Do you know if I can have one project targeted for both platforms. I don't care for backwards compatibility for older version then 2007.

Answer 1

An AddIn targeting 2007 should also work in Office 2010, or you can use a 2010 AddIn in Office 2007 as long as you don't use any of the new features int 2010.
