We need to see your code... You can always replace MsoTriState constants with its values.

The assembly name you need to reference in your project is office.dll. Microsoft.Office.Core is the name of the namespace in the assembly.

Are you sure that your project actually has a reference to the office.dll assembly? (if you click "Show All Files" in Solution Explorer, does the References node include entry for "Office"?).

If you do already have a reference to the office.dll assembly, make sure you are referencing the 12.0.0.0 version (Office 2007), not 11.0.0.0 (Office 2003) or some other version.
