New Post: The type or namespace name 'NetOffice' could not be found (are you missing a using directive or an assembly reference?)

Hi,

I am referring the required NetOffice dlls in a Windows service application
to convert docs to pdf.

'Embed Interop Types' property is missing on NetOffice and all other referred NetOffice dll's properties window.

When I try to build the project, I am getting this error.
"The type or namespace name 'NetOffice' could not be found (are you missing a using directive or an assembly reference?)"

Could you please help me with this.

Thank you
