Please Note:
AJAX functionality is integrated in ASP.NET 3.5 and does not require any additional downloads. If you are using ASP.NET 3.5 this article does not apply to you.

Getting Started with our AJAX Application

Before, in our first with our AJAX Web framework that we use to create a project to download the AJAX framework, and start coding system will require the installation of our do.
Heading in our previous article "Getting Started with AJAX, ASP.NET 2.0 and C#“ we went through the steps involved to install AJAX and how to AJAX enable Visual Studio. We explained where to go to find out about AJAX and that you could download step by step tutorials that will guide you through using every control within the AJAX Control Toolkit.
