How to use Excel Interop on lower version (.Net) ?

Question

In C#, I'm using the Microsoft.Office.Interop.Excel reference v12.0.0.0, which (I think) corresponds to Office 2007.

I guess that my program won't run on computers without Office 2007 or above ? What should I do ?

Answer 1

Use late binding and write your code to only use features available in the lowest version that you want to support.
