1. What is ASP.NET Core?
ASP.NET Core is a cross-platform, open-source web framework for building modern, cloud-based, and internet-connected applications.
It's a part of the .NET platform and is designed to provide high-performance,
scalable, and modular web applications.
2. What are the key features of ASP.NET Core?
Cross-platform support.
Built-in dependency injection.
Unified MVC and Web API frameworks.
Middleware-based pipeline.
Support for modular, self-contained applications.
Ability to run on .NET Core or .NET Framework.
High performance and improved response time.
3. What is the difference between ASP.NET Core and ASP.NET Framework?
ASP.NET Core is cross-platform, while ASP.NET Framework is limited to Windows.
ASP.NET Core has a modular and lightweight architecture, whereas ASP.NET Framework is monolithic.
ASP.NET Core supports built-in dependency injection, which is not present in ASP.NET Framework.
ASP.NET Core has a unified MVC and Web API framework, while in ASP.NET Framework,
these are separate.
4. Explain the ASP.NET Core Middleware.
Middleware is a pipeline of components that process requests and responses. Each component can execute before or after the next one.
Middleware allows you to add various functionalities to the request/response processing pipeline, such as logging, authentication, and caching.
5. What is Dependency Injection (DI) in ASP.NET Core?
Dependency Injection is a design pattern used to achieve loose coupling between classes by injecting their dependencies instead of creating them directly within the class.
In ASP.NET Core, DI is built-in and helps manage the application's components and services
more effectively.
6 What are the different types of Dependency Injection in ASP.NET Core?
Constructor Injection
Property Injection
Method Injection
7. Explain the difference between TempData and ViewBag in ASP.NET Core.
TempData: TempData is used to pass data between two consecutive requests. It's typically used
for redirect scenarios, where data needs to be preserved during the redirection.
ViewBag: ViewBag is used to pass data from a controller to a view. It uses a dynamic property,
so its values can be accessed directly in the view.
8 What is the purpose of the appsettings.json file in ASP.NET Core?
The appsettings.json file is used to store configuration settings for an ASP.NET Core application. It allows you to define various configurations,
such as database connection strings, logging settings, and other application-specific settings.
9. Explain the concept of Tag Helpers in ASP.NET Core.
Tag Helpers are a feature in ASP.NET Core MVC that allows you to create reusable components for generating HTML markup in Razor views.
They help to maintain a clear separation between HTML and C# code and make the views
cleaner and easier to read.
10. How can you implement authentication and authorization in ASP.NET Core?
ASP.NET Core provides built-in support for authentication and authorization through various middleware, including Identity, JWT (JSON Web Tokens),
and OAuth. You can use these middleware to authenticate users and control access to different
parts of your application.
