The namespace provides extension methods that you can access on Microsoft.Office.Interop.Word.Document objects to extend Microsoft Office Word documents.
The extension methods in this namespace are provided for backward compatibility with Office projects that you retarget from the .NET Framework 3.5 to the .NET Framework 4. In new projects that target the .NET Framework 4, you should access these methods by using the Globals.Factory object in your project. For more information, see Extending Word Documents and Excel Workbooks in Application-Level Add-ins at Run Time and Getting Extended Objects from Native Office Objects in Document-Level Customizations.
