Scott Mitchell provides a summary of the new features of ASP.NET 3.5 and Visual Studio 2008. It turns out there aren't a lot of differences between ASP.NET versions 3.5 and 2.0. These are the main new features of version 3.5
- Integrated ASP.NET AJAX support,
- The ListView control, and
- The DataPager control
I'm very happy to see that with Visual Studio 2008 you are able to target which version of .NET you want to code against. This was a real plan with VS 2003 vs VS 2005.
