Asp.net Core:
ASP.NET Core is a new version of ASP.NET by Microsoft. It is an open-source web framework which can be run on Windows, Mac, or Linux.
ASP.NET Core is a free, open-source and cloud optimized web framework which can run on Windows, Linux, or Mac. You can say that it is the new version of ASP.NET. The framework is a complete rewrite from scratch in order to make it open source, modular and cross-platform. It was initially launched as ASP.NET 5 but then it was renamed to ASP.NET Core.
ASP.NET Core is designed to be deployed on cloud as well as on-premises. Developers can now build cloud-based web applications, IoT (Internet of Thing) and mobile backend applications using ASP.NET Core framework which can run on Windows, Linux, and Mac operating systems.
ASP.NET Core is an open source framework supported by Microsoft and the community, so you can also contribute or download the source code from the respective repositories on Github.

.NET Core
Many people are confused between ASP.NET Core and .NET Core. Please note that ASP.NET Core and .NET Core are not the same. They are different, just like ASP.NET and .NET Framework are different.
.NET Core is a fast, lightweight, modular and open source framework for creating web applications and services that run on Windows, Linux and Mac. So, it is a platform on which ASP.NET Core application runs.
Benefits ASP.NET Core?
- Supports Multiple Platforms: ASP.NET Core applications can run on Windows, Linux, and Mac. So you don't need to build different apps for different platforms using different frameworks.
- Fast: ASP.NET Core no longer depends on System.Web.dll for browser-server communication. ASP.NET Core allows us to include packages which we need for our application. This reduces the request pipeline and improves the performance and scalability.
- IoC Container: It includes built-in IoC container for automatic dependency injection which makes it maintainable and testable.
- Integration with Modern UI Frameworks: It allows you to use and manage modern UI frameworks such as AngularJS, ReactJS, Umber, Bootstrap etc. using Bower (a package manager for the web).
- Hosting: ASP.NET Core web application can be hosted on multiple platforms with any web server such as IIS, Apache etc. It is not dependent only on IIS as a standard .NET Framework.
- Code Sharing: It allows you to build a class library which can be used with other .NET frameworks such as .NET Framework 4.x or Mono. Thus a single code based can be shared across frameworks.
- Side-by-Side App Versioning: ASP.NET Core runs on .NET Core which supports simultaneous running of multiple versions of applications.
- Smaller Deployment Footprint: ASP.NET Core application runs on .NET Core which is smaller than full .NET Framework. So, the application which uses only a part of .NET CoreFX will have smaller deployment size. This reduces the deployment foot print.
