Using VS2008 to Target .NET Framework 2.0 with ASP.NET AJAX

from: http://blogs.msdn.com/brada/archive/2007/12/19/using-vs2008-to-target-net-framework-2-0-with-asp-net-ajax.aspx

VS 2008 fully supports building applications for .NET Framework 2.0…   This is very important as it will take time for some hosters and IT organizations to fully deploy .NET Framework 3.5, but you don’t want that to block you from taking full advantage of the cool features in VS 2008.

Today we released ASP.NET 2.0 AJAX Templates for VS2008.  This release contains project templates for using Visual Studio 2008 or Visual Web Developer 2008 to create new web sites and web applications with ASP.NET AJAX Extensions features. The project templates contain specific references to assemblies in .NET Framework 2.0 and ASP.NET 2.0 AJAX Extensions 1.0.

Download the ASP.NET 2.0 AJAX Templates for VS2008!

To try these out, make sure you have ASP.NET AJAX Extensions installed, then install the ASP.NET AJAX Templates for Visual Studio 2008.

Then, go to File->New Project and select .NET Framework 2.0 as the target runtime.  That will filter down the options and you should see “AJAX 1.0-Enabled ASP.NET 2.0 Web Application”.  Select it.

Notice the assembly reference in web.config is fixed up to be the 1.0 version number…

 <system.web>
    <pages>
      <controls>
        <add tagPrefix="asp" namespace="System.Web.UI" 
             assembly="System.Web.Extensions, Version=1.0.61025.0, ...
      </controls>
    </pages>

Ext JS: cross-browser JS library for building rich web apps

A Senior PM from work put me onto ExtJS which is a useful looking active style js ajax library.

It includes:

• High performance, customizable UI widgets
• Well designed and extensible Component model
• An intuitive, easy to use API
