What's New in Office Development

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

This topic describes changes that have been made to Office development tools in the Visual Studio 11 Developer Preview release.

New Office Projects Target only Microsoft Office 2010 and the .NET Framework 4

You cannot create new Office projects that target the 2007 Microsoft Office system or the .NET Framework 3.5 by using Visual Studio 11 Developer Preview. Office project templates in the current version of Visual Studio target only Microsoft Office 2010 and the .NET Framework 4.

For more information, see How to: Create Office Projects in Visual Studio.

Upgraded Document-Level Projects Target Only Microsoft Office 2010 and the .NET Framework 4

When you upgrade a document-level customization project in Visual Studio 11 Developer Preview, Visual Studio modifies the project to target Microsoft Office 2010 and the .NET Framework 4. If the document in your project has a binary format, such as documents that have an .xls or .doc extension, Visual Studio converts the document to the Office Open XML format.

Application-level projects can continue to target the 2007 Microsoft Office system and the .NET Framework 3.5.
