Q: What is the difference between ASP.NET and ASP.NET Core?
A: ASP.NET Core is a cross-platform, open-source, and modular web framework, whereas ASP.NET is a Windows-only web framework that is not open-source. ASP.NET Core also has improved performance and supports cross-platform development.
Q: What is the use of the ConfigureServices method in ASP.NET Core?
A: The ConfigureServices method is used to configure services that are used by the application, such as dependency injection, authentication, and authorization services.
Q: What is dependency injection in ASP.NET Core?
A: Dependency injection is a design pattern used to create and manage dependencies between objects in an application. ASP.NET Core has built-in support for dependency injection, which makes it easier to manage dependencies and create more modular and testable code.
Q: How do you implement authentication and authorization in ASP.NET Core?
A: Authentication and authorization can be implemented in ASP.NET Core using middleware components, such as the Authentication and Authorization middleware. ASP.NET Core also has built-in support for popular authentication providers, such as OAuth and OpenID Connect.
Q: What is the difference between Razor Pages and MVC in ASP.NET Core?
A: Razor Pages is a new feature in ASP.NET Core that allows developers to create web pages with less overhead than traditional MVC applications. Razor Pages are simpler and have less code, but they are less flexible than MVC applications.
Q: How do you deploy an ASP.NET Core application?
A: ASP.NET Core applications can be deployed to various platforms, including Windows, Linux, and Docker containers. You can deploy an ASP.NET Core application using various methods, such as deploying to a web server or deploying to a cloud platform like Azure.
Q: What is SignalR in ASP.NET Core?
A: SignalR is a real-time communication library for ASP.NET Core that allows developers to add real-time functionality to web applications, such as chat applications, stock tickers, and real-time dashboards. SignalR uses WebSockets by default but can fall back to other communication protocols if WebSockets are not supported.
