1. What is Full Stack Development, and how does it differ from Back-end and Front-end development?
1. Full Stack Development involves working on both the front-end and back-end aspects of web development, encompassing tasks such as user interface design, server-side programming, and database management. Unlike front-end development, which focuses solely on user interaction and presentation, and back-end development, which handles server-side logic and data storage, Full Stack Development requires proficiency in both areas to create end-to-end solutions.
2. Explain the MVC (Model-View-Controller) architecture in ASP.NET.
2. The MVC (Model-View-Controller) architecture in ASP.NET separates an application into three components: the Model (data and business logic), the View (user interface), and the Controller (handles user input and updates the model accordingly), promoting modularity, scalability, and maintainability.
3. What are the different types of authentication supported in ASP.NET Core?
3. The different types of authentication supported in ASP.NET Core include cookie-based authentication, token-based authentication (such as JWT), OAuth authentication for external providers, Windows Authentication for intranet applications, and ASP.NET Core Identity for managing users, roles, and claims.
4. Describe the role of Entity Framework in .NET development.
4. Entity Framework in .NET development serves as an Object-Relational Mapping (ORM) framework, facilitating the interaction between .NET applications and relational databases by abstracting database operations into object-oriented code, thereby simplifying data access and manipulation tasks.
5. What is ASP.NET Core middleware and how is it used?
. ASP.NET Core middleware are components that handle requests and responses in the application's request pipeline, enabling cross-cutting concerns such as logging, authentication, and error handling to be added to the application's processing flow in a modular and reusable manner.
6. Explain the concept of dependency injection in ASP.NET Core.
Dependency injection in ASP.NET Core is a design pattern where objects depend on abstractions instead of concrete implementations, allowing dependencies to be injected into a class rather than being created within it. This approach promotes loose coupling, easier testing, and better maintainability by enabling components to be easily replaced or modified without impacting other parts of the application. In ASP.NET Core, dependency injection is built into the framework, allowing services to be registered and injected into controllers, views, and other components throughout the application, thereby promoting modularity and flexibility in application design.
7. Explain the concept of dependency injection in ASP.NET Core.
Dependency injection in ASP.NET Core is a design pattern where classes depend on abstractions (interfaces or abstract classes) rather than concrete implementations, allowing dependencies to be injected into a class rather than created within it. This promotes loose coupling, modularization, and easier testing by decoupling the components of an application and facilitating the replacement or modification of dependencies without impacting other parts of the system.
8. What is the difference between ASP.NET Web Forms and ASP.NET MVC?
The main difference between ASP.NET Web Forms and ASP.NET MVC is their architectural approach: ASP.NET Web Forms uses a stateful, event-driven programming model, while ASP.NET MVC follows the Model-View-Controller pattern, promoting separation of concerns and better control over HTML output.
9. What are the advantages of using Razor Pages in ASP.NET Core?
The advantages of using Razor Pages in ASP.NET Core include simplified development, increased productivity, improved maintainability, and enhanced performance. Razor Pages offer a more straightforward and focused development model compared to MVC, allowing developers to create web applications with less ceremony and boilerplate code. This results in faster development cycles and improved productivity. Additionally, Razor Pages promote better code organization and separation of concerns, making it easier to maintain and refactor code as applications evolve. Furthermore, Razor Pages tend to have better performance compared to traditional ASP.NET Web Forms due to their lightweight nature and optimized rendering process. Overall, Razor Pages provide a modern and efficient approach to building web applications in ASP.NET Core.
10. How do you handle authentication and authorization in a .NET Core application?
Authentication and authorization in a .NET Core application can be handled using ASP.NET Core Identity, which provides built-in support for managing users, roles, and claims. This includes features such as user registration, login, password management, and role-based access control (RBAC), allowing developers to easily integrate authentication and authorization functionalities into their applications with minimal effort. Additionally, ASP.NET Core Identity supports various authentication mechanisms such as cookies, tokens (JWT), and external providers (OAuth), providing flexibility to choose the most suitable approach for different scenarios.
