In this article, we will learn how to create a console application and a web application using ASP.NET Core and how to publish the application on a local system. 

What is ASP.NET Core?

ASP.NET Core is a new and open source version of  ASP.NET Core, released by Microsoft. It is a cross-platform web framework to build applications which can be run on different platforms like Windows, Mac, and Linux.

Why ASP.NET Core?

  • It supports cross-platform.
  • It is faster and simplifies modern web app development.
  • It provides in-built support for IoC Container.
  • It allows us to integrate with modern UI framework.
  • Its hosting can be done on any server, like IIS, Apache, or self-hosting in our own process.
  • It supports Side-by-Side app versioning.
