I am exporting to Excel from a C# Winform Application. With my customer base
my application must support Office 2002 to Office 2007. If I use the 11.0
object model I am only compatible back to 2003 (I think)

For my Word interoperability I went with the DSOFramer and the
Interop.Word.dll which provided a version independent layer that solved the
problem in Word.

Now although the DSOFramer seems to support Excel I can not find an
equivalent Interop.Excel.dll.

Any suggestions for the proper approach?
