Welcome to the Word 2013 Primary Interop Assembly Reference

Office 2013 and later

The Word 2013 Primary Interop Assembly (PIA) Reference provides help for developing managed applications for Word. It extends the Word 2013 Developer Reference from the COM environment to the managed environment and focuses on how to use the PIA.

If you use Office Developer Tools for Visual Studio 2013 and you are connected to the Internet, you can access context-sensitive Help when you press F1 in the Visual Studio integrated development environment (IDE). This Help content is the Word 2013 PIA Reference posted on MSDN.
