Microsoft Office Object Libraries for Multiple Versions of Excel

Hi.  I need to develop a C# Excel add-in for multiple versions of Excel: Excel 2003, Excel 2007, and Excel 2010.  Do I need to change the referenced version of the Microsoft Office Object Library--11.0, 12.0, and 14.0--, recompile, and create a different installer for each version of Excel?  Hopefully, there is an easier way?  Thank you.

You COULD do that.

However...........
You should find this post useful, and while it talks about office 2003 + 2007, I'm positive the concept extends to Office 2010.

It appears you can develop one version compatible with 2003, or you can develop the 3 projects then put the code in a shared assembly.
