I'm currently doing some development in 10. I am developing an AddIn. I was just recently told I would also have to support 9.3. Is there any way I can develop my addin to work in both 9.3 and 10? Otherwise, I only see 2 options: 1. Maintain 2 projects 2. Discontinue development of the Addin altogether, and go back to an arcobjects extension. Neither of which I prefer to do.
