What is ASP.NET - Part 1

ASP.NET is a Web application framework developed by Microsoft to build dynamic data driven Web applications and Web services. 
1. ASP.NET is a subset of .NET framework. In simple terms a framework is a collection of classes. 
2. ASP.NET is the successor to classic ASP (Active Server Pages).

What other technologies can be used to build web applications
1. PHP
2. Java
3. CGI
4. Ruby on Rails
5. Perl



What is a Web Application?
A web application is an application that is accessed by users using a web browser. Examples of web browsers include 
1. Microsoft Internet Explorer
2. Google Chrome
3. Mozilla FireFox
4. Apple Safari
5. Netscape Navigator

What are the advantages of Web applications?
1. Web Applications just need to be installed only on the web server, where as desktop applications need to be installed on every computer, where you want to access them.
2. Maintenance, support and patches are easier to provide.
3. Only a browser is required on the client machine to access a web application.
4. Accessible from anywhere, provided there is internet.
5. Cross Platform



How Web applications work?
1. Web applications work on client/server architecture
2. On the client all you need is a browser, that can understand HTML
3. On the server side, the Web application runs under Microsoft Internet Information Services (IIS)

How web applications work

When the client enters the URL of the web application in the browser, and submits the request. The web server which hosts the web application, receives the request. The request is then processed by the application. The application generates, the HTML and hands it over to the IIS (web server). Finally, IIS sends the generated HTML to the client, who made the initial request. The client browser will the interpret the HTML and displays the user interface. All this communication, happens over the internet using HTTP protocol. HTTP stands for Hyper Text Transfer Protocol. A protocol is a set of rules that govern how two or more items communicate.

      Hi Maran, thank you very much for the feedback. At the moment I don't have any videos on IIS. Can you please let me know, what you are looking for as far as IIS is concerned. If, you are looking for creating a virtual directory and pointing that to a web application, and accessing the application thru that IIS, rather than using the visual studio built in development server. This is something, I am planning to cover in the very near future. Again, thank you very much for taking your time to give the feedback.

    Hi Venkat,

    I am very much impressed looking at your videos and each and every topic has covered a lot in detail in a short span of each video and every bit of it was useful.

    Do you have idea of doing videos on MVC or Entity framework.

    Hi Venkat,

    First of all Thanks a lot for this fantastic learning videos.
    I have one doubt in View state. As per your videos if I disable "Enableviewstate" property of text box, it will not retain State.
    But when I tried practically, despite of disabling the view state, textbox is able to retain data in turn state.

    Hello Venkat,

    As we know asp.net application needs a Web browser and Web server.
    now here, why web server supports only HTML language and why?
    And, Why communication protocol is only HTTP why not TCP/IP.

    Thanks & Regard
