How to Install Dotnet Core on Ubuntu

In this article, we'll explain how to install Dotnet Core on Ubuntu.

.NET Core is a free, cross-platform, open-source developer platform for building many different types of applications. Software developers often need to use the Dotnet core framework on the Linux system to test, run, and build the packages.

The notion of using Dotnet on Linux comes true through the new Dotnet core, which is an API based modular system of Microsoft’s Dotnet framework. But the Dotnet core doesn’t act as a single API; it functions as a shared or public library of API and codes.

Prerequisites

• An Ubuntu installed system.
• A root user access of normal user with administrative privileges.
