Why Use Asp.Net Core?

• Cross platform- It can run on Windows, Linux and Mac.
• Better performance- net core does not depend on system.web.dll for communication between Browser-server. In Asp.net core everything is packages which we need for our application. Packages reduce the request pipeline and improve application performance.
• Dependency Injection- Dependency Injection is in-built in Asp.Net Core.
• Integration with Modern UI Frameworks- It supports modern UI like Angular, ReactJS and Bootstrap etc.
• Hosting-Net Core application can be hosted on multiple Web server such as IIS, Apache, Docker etc. It is not dependent on IIS.
• Open Source- It is a fully open source framework.
• Testability- Unit testing is very easy in Asp.Net core application.
• Side-by-side App Versioning-Net Core runs on .NET Core, which supports simultaneously running in multiple versions of applications.
• Unified Programming Model for MVC and Web API-In Asp.Net Core both MVC Controller and API Controller are Inherits from the same controller base class.
