Built-In Asynchronous I/O Support in ASP.NET

As we all know, I/O operations is one of the most time consuming operations. In the same time, IO is one of the most needed operations almost in all applications. To make our applications faster and having more responsive user interface, we need to perform those I/O operations asynchronously.

So, this is a common scenario, frequently needed and frequently used.

To make your life easier, many .NET framework classes that provide I/O services come with built-in methods that support and implement the asynchronous execution pattern. This saves you from creating and instantiating delegates to run the I/O operations asynchronously.

This tutorial present the most common I/O scenarios, with their built-in asynchronous execution patterns.

ASP.Net Web Requests

Not a new article, but good reading. All you need to know about HTTP requests, including page life cycle.

Introduction

The purpose of this document is to provide a very thorough explanation of what happens during an HTTP request to an ASP.NET page being served up through IIS. It starts out with the basics but then dives in to the gory details, more detail than is probably needed for basic web page development. However a thorough knowledge of this process is invaluable when debugging strange problems, developing ASP.NET custom web controls or developing any sort of web framework.

Firebug demo

If you're a serious web developers Firebug is a must have. Pity it's only available with Firefox, but hey worth the jump.

Its creator, Joe Hewitt has done a demo video of Firebug potential.

The video shows you the subtle features within:

• Highlighting the DOM that you know your Ajax call will eventually update, and see Firebug showing you what is updated
• The profiler at work: the difference between time spent only in that function, versus including recursive calls into other functions
• Tying into the profiler from your code
• Tips and tricks for the inspector, profiler, network, and more
