Multi-targeting is a new feature in Visual Studio 2008 that allows developers to choose which .NET Framework they want to target for a given project. Available choices are 2.0, 3.0 and 3.5, and you may change your selection after a project has already been created. The IDE filters selectable features and the build system generates appropriate warnings based on whether a particular feature is available in the target platform.

The purpose of this demo/lab is to show how multi-targeting is implemented in Visual Studio 2008. The lab covers the following topics:

• Multi-targeting in the New Project dialog
• Target Framework-based filtering in Add New Item and Add Reference dialogs
• Target switching via project Properties dialog • Build- and compiler-generated errors and warnings based on Target Framework
