One of the great new features of VS 2008 is its support for framework multi-targeting. This enables you to use VS
2008 on .NET 2.0, .NET 3.0 and .NET 3.5 projects, and does not require you to
upgrade your projects to the latest version of the .NET Framework in order to
take advantage of new Visual Studio 2008 features (like JavaScript Intellisense, JavaScript Debugging, code editing, nested master pages, and the improved web designer and CSS features - all of which work
with .NET 2.0, 3.0 and 3.5 projects).
