2. ASP.NET is an open-source[2] server-side web application system intended for web improvement to create dynamic site pages. It was created by Microsoft to enable developers to fabricate dynamic sites, web applications and web administrations.

3. It was first discharged in January 2002 with adaptation 1.0 of the.NET Framework, and is the successor to Microsoft's Active Server Pages (ASP) innovation. ASP.NET is based on the Common Language Runtime (CLR), enabling software engineers to compose ASP.NET code utilizing any bolstered.NET dialect. The ASP.NET SOAP augmentation system enables ASP.NET segments to process SOAP messages.

4. Code-behind model : Microsoft suggests managing dynamic program code by utilizing the code-behind model, which puts this code in a different record or in a uniquely assigned content tag. Code-behind records commonly have names like "MyPage.aspx.cs" or "MyPage.aspx.vb" while the page document is MyPage.aspx (same filename as the page record (ASPX), yet with the last expansion meaning the page dialect). This training is programmed in Visual Studio and different IDEs, however the client can change the code-behind page. Likewise, in the web application arrange, the pagename.aspx.cs is a fractional class that is connected to the pagename.designer.cs document.

5. The creator record is a record that is autogenerated from the ASPX page and enables the software engineer to reference parts in the ASPX page from the CS page without declaring them physically, as was essential in ASP.NET forms before rendition 2.[8] ASP.NET When utilizing this style of programming, the designer composes code to react to various occasions, for example, the page being stacked, or a control being clicked, as opposed to a procedural walkthrough of the archive.

6. ASP.NET's code-behind model denotes a takeoff from Classic ASP in that it urges engineers to fabricate applications because of partition of introduction and substance. ASP.NET'ASP In principle, this would permit a Web planner, for instance, to center around the outline markup with less potential for aggravating the programming code that drives it. This is like the partition of the controller from the view in model– view– controller (MVC) structures.

7. Orders An order is an exceptional guideline on how ASP.NET should process the page.[9] The most widely recognized mandate is, which can indicate numerous properties utilized by the ASP.NET page parser and compiler.ASP.NET

8. State administration State administration ASP.NET applications are facilitated by a Web server and are gotten to utilizing the stateless HTTP convention. In that capacity, if an application utilizes stateful cooperation, it needs to actualize state administration all alone. ASP.NET ASP.NET gives different capacities to state administration. Adroitly, Microsoft treats "state" as GUI state. Issues may emerge if an application must track "information state"; for instance, a limited state machine that might be in a transient state between demands (languid assessment) or sets aside a long opportunity to instate ASP.NET
