Introduction to working with the ExtJS framework combined with a .NET backend. There is a big difference of working with classic ASP.NET pages using the postback model as compared to a web service oriented RIA application. <br/>
I'll go through setting up ExtJS to work with .NET web services and cover some of the pitfalls I've run into in the past. I'll briefly cover client side debugging, caching, performance tweaks and show development tools that increase productivity, such as JsLint/Fiddler/Firebug/YSlow.

I'll add the code files later tomorrow hopefully. If you have any questions, don't hesitate to contact me at email@example.com
