The extension methods in the WorkbookExtensions class are provided for backward compatibility with Office projects that you retarget from the .NET Framework 3.5 to the .NET Framework 4or the .NET Framework 4.5. In new projects that target the .NET Framework 4 or the .NET Framework 4.5, you should call the GetVstoObject and HasVstoObject methods that are provided by the Globals.Factory object in your project. For more information, see Extending Word Documents and Excel Workbooks in VSTO Add-ins at Run Time and Programming Document-Level Customizations.
