ASP .NET is a web development platform, which gives a programming version, a complete software program infrastructure, and various offerings required to build up robust internet packages for computers, as well as cell gadgets.
ASP .NET works on the pinnacle of the HTTP protocol and makes use of the HTTP commands and guidelines to set a browser-to-server bilateral communique and cooperation.
Asp .Net is part of the Microsoft .Net platform. Asp.Net packages are compiled codes, written the usage of the extensible and reusable components or gadgets present within the .NET framework. Those codes can use the whole hierarchy of classes in the .NET framework.
The ASP .NET application codes can be written in any of the following languages:
ASP .NET is used to produce interactive, data-driven web applications over the internet. It consists of a large number of controls such as text boxes, buttons, and labels for assembling, configuring, and manipulating code to create HTML pages.
ASP.NET web forms extend the event-driven model of interaction to web applications. The browser submits a web form to the web server and the server returns a full markup page or HTML page in response.
All client-side user activities are forwarded to the server for stateful processing. The server processes the output of the client actions and triggers the reactions.
Now, HTTP is a stateless protocol. ASP.NET framework helps in storing the information regarding the state of the application, which consists of:
The page state is the state of the client, i.e., the content of various input fields in the web form. The session state is the collective information obtained from various pages the user visited and worked with, i.e., the overall session state. To clear the concept, let us take an example of a shopping cart.
The user adds items to a shopping cart. Items are selected from a page, say the items page, and the total collected items and price are shown on a different page, say the cart page. Only HTTP cannot keep track of all the information coming from various pages. ASP.NET session state and server-side infrastructure keep track of the information collected globally over a session.
The ASP .NET runtime carries the page state to and from the server across page requests while generating ASP .NET runtime codes, and incorporates the state of the server-side components in hidden fields.
This way, the server becomes aware of the overall application state and operates in a two-tiered connected way.
The ASP .NET component model provides various building blocks of ASP .NET pages. It is an object model, which describes:
Asp .Net is an era, which goes on the .Net framework that consists of all internet-associated functionalities. The .Net framework is fabricated from an item-orientated hierarchy. An asp .Net web application is a product of pages. Whilst a person requests an ASP .NET page, the IIS delegates the processing of the web page to the ASP .NET runtime system.
The asp .Net runtime transforms the .aspx page into an instance of a class, which inherits from the bottom class web page of the .NET framework. Therefore, each ASP .NET page is an item and all its components i.E., the server-facet controls also are items.
Before going to the next session on Visual Studio.Net, let us go through the various components of the .Net framework 3.5. The following table describes the components of the .Net framework 3.5 and the job they perform:
