Asp.Net Core and .Net Core Both are different, just like Asp.Net and .Net Framework.
Why Use .Net Core?
- Cross platform - It can run on Windows, Linux and Mac.
- Unified - It offers a single unified component like .NET Standard library for all platforms with the same code, same languages, and same tools.
- Better performance - .Net core does not depend on system.web.dll for communication between Browser-server. In .Net core everything is packages which we need for our application. Packages reduce the request pipeline and improve the application performance.
- Lightweight - It is a lightweight framework. It allows developers to deploy libraries and components that are needed in a set of packages.
- Dependency Injection - Dependency Injection is in-built in .Net Core.
- 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. That means, it is free of cost and its source code is available.
- Testability - Unit testing is very easy in .Net core application.
- Side-by-side App Versioning - .Net Core runs on .NET Core, which supports simultaneously running in multiple versions of applications.
