ASP.NET Web Forms ASP.NET WebForms is a web application platform supported by Microsoft ASP.NET technology, and one of many programming models. WebForms software, such as C # or Visual Basic, can be written in any programming language that supports the common language run time. WebForms pages’ key building blocks are server controls, which are modular components that are responsible for rendering the HTML markup and reacting to events. A technique called view state is used in normally stateless HTTP requests to maintain the server controls status. ASP.NET MVC The ASP.NET MVC is a Microsoft-developed, discontinued web application architecture that implements model – view – controller (MVC) design. It is open-source software, apart from the proprietary ASP.NET Web Forms component. ASP.NET Core, which combined ASP.NET, ASP.NET MVC, ASP.NET Web API, and ASP.NET Web Pages, has been released since. Difference between Asp.Net WebForms and Asp.Net MVC: Asp.Net WebForms Asp.Net MVC 1. Asp. Net Web Form follows a conventional model of growth, guided by events. 1. Asp. Net MVC is a lightweight architecture based on the design, layout, and follows MVC (Layout, View, and Controller). 2. Asp. Net Web Type has controls over the servers. 2. Asp. Net MVC has Code Assistants. 3. Asp. Net Web Template allows state presentations on the client-side for state management. 3. Asp. Net MVC does not support the state of the view. 4. Asp. Net Web Type has file-based URLs which means the file name in the URLs must be physically present. 4. Asp. Net MVC has route-oriented URLs which means that URLs are divided into controllers and activities and are also oriented on controllers and not on physical files. 5. Asp. Net WebForms follows the Syntax of Web Formats. 5. Asp. Net MVC follows the syntax that can be customized. 6. WebForms (ASPX) i.e. views are closely related to code-behind (ASPX.CS), i.e. logic, in the Asp. Net Web Type. 6. Views and logic are held separately within Asp. Net MVC. 7. Asp. Net Web Design has a clear look and feels for the Master Pages. 7. Asp. Net MVC has templates to provide a consistent look and feel. 8. Asp. Net Web Template has User Controls for the reusability of code. 8. Asp. Net MVC has Limited Reusability Views for application. 9. Asp. Net Web Type has integrated data controls and is ideally designed for quick growth with efficient access to data. 9. Asp. Net MVC is lightweight, provides complete markup control, and supports a variety of features that allow fast & agile development. It is, therefore, best to build an interactive Web application with the new web standards. 10. Asp.Net Web Form is not Open Source. 10. Asp. Net is an Open Source Internet MVC.
