What You Need to Use This Book

ASP.NET 2.0 AJAX Extensions 1.0 builds on top of ASP.NET 2.0, so you will need to have version 2.0 of the .NET Framework installed. There are two separate types of download for the .NET Framework. The redistributable package is what is required for application to run and needs to be on development, test, and server machines. The SDK (Software Development Kit) is a set of tools for use in developing applications. Both are available from http://msdn2.microsoft.com/en-us/netframework/aa731542 .aspx. The examples use Visual Web Developer. The free Express version is available at http://msdn .microsoft.com/vstudio/express/web.
