The comparison between Frameworks in Visual Studio
The core assemblies installed from the .NET Framework version 2.0 are still used by the 3.0 and 3.5 versions. In ASP.NET 3.5 doesn't change or take away or break any functionality, concepts, or code present in 2.0 - it simply adds new types and features and capabilities to the framework.
The VS 2008 is multi-targeted, meaning that you choose from a drop-down list whether to have Visual Studio 2008 build applications against the ASP.NET 2.0, 3.0, or 3.5 frameworks.
VS 2008 also includes an improved Designer experience, JavaScript debugging and IntelliSense features, and the ability to view and even step into the core .NET Framework code during debugging.
The following picture highlights the features in .NET 2.0 and the features added in .NET 3.0 and then in .NET 3.5:

For more background on how .NET 3.5 is mere additional assemblies and functionality added atop the existing .NET 2.0 base, refer to Daniel Moth's blog entry, .NET Framework 3.5. Also from Daniel's blog, the Visual Studio 2008 Stack helps paint a clear picture with regards to the changes in Visual Studio, the programming languages, the framework libraries, and the CLR over time:
New Visual Studio 2008 Features
Visual Studio 2008 offers an improved developer experience through a number of new features, including an improved Designer, more modern CSS editing options, and enhanced JavaScript debugging and development support. Visual Studio 2008 can target web applications to the .NET 2.0, .NET 3.0, or .NET 3.5 environments, meaning you can start using Visual Studio 2008 today to work on your ASP.NET 2.0 websites.
