New Features in ASP.NET 3.5 ASP.NET AJAX In ASP.NET 2.0, ASP.NET AJAX was used as an extension to it. You had to download the extensions and install it. However in ASP.NET 3.5, ASP.NET AJAX is integrated into the .NET Framework, thereby making the process of building cool user interfaces easier and intuitive. The integration between webparts and the update panel is much smoother. Another noticeable feature is that you can now add ASP.NET AJAX Control Extenders to the toolbox in VS2008. Even though this is an IDE specific feature, however I feel it deserves a mention over here for developers, who had to add extenders using source view earlier. It is also worth noting that Windows Communication Foundation (WCF) now supports JSON along with other standard protocols like SOAP, RSS and POX. New Controls The ListView and DataPager are new controls added along with a new datasource control called the LinqDataSource. ListView The ListView control is quiet flexible and contains features of the Gridview, Datagrid, Repeater and similar list controls available in ASP.NET 2.0. It provides the ability to insert, delete, page (using Data Pager), sort and edit data. However one feature of the ListView control that stands apart, is that it gives you a great amount of flexibility over the markup generated. So you have a complete control on how the data is to be displayed. You can now render your data without using the tag. You also get a rich set of templates with the ListView control. DataPager DataPager provides paging support to the ListView control. The best advantage is that you need not have to keep it ‘tied’ with the control on which the paging is being done. You can keep it anywhere on the page. DataPager gives you a consistent way of paging with the controls that support it. Currently only ListView supports it as it implements the IPageableItemContainer. However support is likely to be added to other List controls as well. LINQ LINQ (Language Integrated Query) adds native data querying capability to C# and VB.NET along with the compiler and Intellisense support. LINQ is a component of .NET 3.5. LINQ defines operators that allow you to code your query in a consistent manner over databases, objects and XML. The ASP.NET LinqDataSource control allows you to use LINQ to filter, order and group data before binding to the List controls. You can learn more about LINQ over here . ASP.NET Merge Tool ASP.NET 3.5 includes a new merge tool (aspnet_merge.exe). This tool lets you combine and manage assemblies created by aspnet_compiler.exe. This tool was available earlier as an add-on. New Assemblies The new assemblies that would be of use to ASP.NET 3.5 developers are as follows: · System.Core.dll - Includes the implementation for LINQ to Objects · System.Data.Linq.dll - Includes the implementation for LINQ to SQL · System.Xml.Linq.dll - Includes the implementation for LINQ to XML · System.Data.DataSetExtensions.dll - Includes the implementation for LINQ to DataSet · System.Web.Extensions.dll: Includes the implementation for ASP.NET AJAX (new enhancements added) and new web controls as explained earlier. Some Other Important Points 1. ASP.NET 3.5 provides better support to IIS7. IIS7 and ASP.NET 3.5 modules and handlers support unified configuration. 2. You can have multiple versions of ASP.NET on the same machine. 3. For those who are wondering what happened to ASP.NET 3.0, well there isn’t anything called ASP.NET 3.0. 4. VS 2002 worked with ASP.NET 1.0, VS 2003 worked with ASP.NET 1.1, and VS 2005 worked with ASP.NET 2.0. However VS 2008 supports multi-targeting, i.e it works with ASP.NET 2.0, and ASP.NET 3.5.

do you really think somebody is spend the time to list the 100s of differences? also, you didn't state what version of the .Net framework you are currently using. if you are currently using 1.1 and you are moving to 3.5, then there will be alot more differences than if you were moving from 3.0 to 3.5. Microsoft has lists of all the changes. YOU search.
