New Feature of ASP.net 2.0 [Asynchronous Pages]

Microsoft's release of .Net Framework 2.0 is become big hit in the market. Definitely there is a reason behind this..
There are lots of improvements and cool features made available in the the latest version of .Net Framework 2.0 (the latest version of .Net Framework is 3.5) compared to its earlier version 1.x. Few of the cool features such as master pages, themes, profiles, new improved grid view,login controls etc etc.. but one of the nice feature which Microsoft has released with .Net Framework 2.0 is "Asynchronous Pages".
In this topic I am mainly going to talk about this "Asynchronous Pages" in .Net Framework 2.0.

Before I proceed I want to discuss bit about what is "Asynchronous" and "Synchronous" process.

In simple term Synchronous waits for the response whereas Asynchronous does not wait for the response..

For example if you are sending a request using synchronous .aspx page for querying a remote database,thread for the request will be alive until and unless remote database send back response back to the requesting page. Since .net framework allows limited thread pool , this can slow down the performance of the application drastically and all other requests to the server will be queued up.

But in case of Asynchronous Pages in .net framework 2.0 thread will return to the thread pool once it sends request to the server and once servern sends request back it takes another thread from the pool and finishes request.

Unwanted Usage of ‘var’ Keyword in c#

Since the introduction of ‘var’ keyword in C# 3.0, lots of developers started using it very large scale mode. I have done code reviews of lots of projects since the introduction of ‘var’ keyword and the trend of ‘var’ keyword is in usage of lots projects, and one thing what I noticed is that, ‘var’ keyword has made developer’s life much easier. If you are from a VB 6.0 background, usage of ‘var’ keyword was strictly prohibited only to certain places, developer should not get confused themselves with ‘var’ keyword from VB 6.0 or in JavaScript which both are totally unrelated. The main purpose behind ‘var’ keyword in C#, is to use it when the type in unknown. For example, I have a method which returns CustomerDetails and it contains information such as Customer ID, CustomerID,CustomerCity,Zip etc. which has different data types. Usage of ‘var’ keyword at everyplace makes code very difficult for other developers to understand. For example, a developer wants to check employee stat
