Office XP PIAs

To make Microsoft Office XP applications available to Microsoft Visual Studio .NET developers, Microsoft has created several primary interop assemblies (PIAs) that contain the official description of commonly used Microsoft Office XP type libaries for applications such as Microsoft Access 2002, Microsoft Excel 2002, and Microsoft FrontPage 2002. Microsoft has customized the Office XP PIAs to make it easier for managed code to interoperate with the Office XP COM type libraries.

Avoid using any Office XP COM interop assembly that is not provided as part of the Office XP PIAs, or any Office XP COM interop assembly that is generated by Microsoft Visual Studio .NET at design time because they are considered unofficial. This version is the first release on CNET Download.com.
