Hi,

I am trying to convert a project with Framework 2.0 to Frameowrk 4.0, and I come into those errors of '...is ambiguous in the namespace 'Microsoft.Office.Interop.Excel''. This is referring to Application, Workbook, Worksheet. I tried to delete the reference and re-add, but still the problems are not fixed.

Does anyone know how to do about it?

Thanks!

Can you post the line of code that gives you the error, and your Imports statement too

Look at the target framework of all of the "projects" in your "solution".

Try to delete the files in the obj and bin folder. An older version might still persist there.

Good luck!
