1 - What is ASP.NET?
ASP.NET is a web development platform used to create web applications and websites. It is part of the .NET framework and provides a robust and secure environment for developing dynamic web pages.
2) What are the different components of ASP.NET?
The main components of ASP.NET are web pages, web forms, MVC, and web API. Web pages are HTML based documents that are executed on the server. Web forms are used for creating interactive web applications. MVC (Model View Controller) is a design pattern used for creating scalable and testable web applications. Web API is used for building HTTP based services that can be consumed by a variety of clients.
3) What is the difference between ASP and ASP.NET?
ASP (Active Server Pages) is a server side scripting language that is used to create dynamic web pages. ASP.NET is an improved version of ASP that allows for the development of complex web applications and provides a more structured environment for coding.
4) What is the difference between ASP.NET web forms and MVC?
Web forms use a drag and drop approach to create web applications and hide most of the complex HTML and JavaScript code from the developers. MVC provides a more structured approach to web development with separate files for models, views, and controllers. It also allows for more control over the generated HTML code.
5) What is ViewState and how is it used in ASP.NET?
ViewState is a hidden field on a web form that stores the state of the page and its controls. It is used to maintain the values of the controls across postbacks, allowing for a stateful behavior of web pages.
6) What is a postback and how is it different from a traditional web request?
A postback is a request sent from the client to the server in response to a user action on a web page, such as clicking a button. In traditional web requests, the entire page is reloaded every time a request is made, whereas in postbacks, only a portion of the page is updated, resulting in a smoother and more efficient user experience.
7) What is code behind in ASP.NET?
Code behind refers to the separation of code used for the logic of a web page from its design and markup. This allows for cleaner and more maintainable code, as well as enabling a team of developers to work on different aspects of the web page simultaneously.
8) What is the difference between Server side and Client side validations?
Server side validations are performed on the server, after the user submits the form, and are used to ensure data integrity and security. Client side validations, on the other hand, are performed on the client's browser using JavaScript, providing immediate feedback to the user.
9) What is the role of the Global.asax file in an ASP.NET application?
The Global.asax file contains application level events and settings, such as Application_Start, which is used to initialize the application on the first request, and Session_Start, which is used to initialize a user's session.
10) What is the difference between session and application state in ASP.NET?
Session state refers to storing data specific to a particular user across multiple requests, while application state refers to data that is shared across all users of the application.
11) What is the use of using statement in C#?
The using statement in C# is used to ensure that an object is disposed of after its use. It automatically calls the Dispose() method on the object.
12) What are some advantages of using ASP.NET for web development?
Some advantages of using ASP.NET include server side rendering, automatic state management, built in security features, and support for multiple languages and frameworks. It also provides a rich set of controls and libraries, making web development faster and more efficient.
13) What is the difference between GET and POST methods in HTTP?

GET and POST are HTTP methods used for sending data to a server. GET sends the data as part of the URL, while POST sends the data in the request body. GET is used for retrieving data, while POST is used for sending data to the server, typically used for form submissions.
14) How can you handle errors in ASP.NET?
ASP.NET provides several methods for handling errors, including built in error pages, custom error pages, and using the Application_Error event in the Global.asax file. Developers can also use try catch blocks to handle errors at the code level.
15) What is the difference between authentication and authorization in ASP.NET?
Authentication is the process of verifying a user's identity, while authorization is the process of determining if a user has access to a specific resource or functionality. ASP.NET provides various authentication options, including Windows Authentication, Forms Authentication, and Single Sign On, and developers can use authorization rules to restrict access to certain parts of the application.
