How to do it...

The first step is to open a web browser and navigate to the http://dot.net/core site. It'll detect a host operating system, and will show downloading and installation steps.

• Installation for Windows:
  On the Windows platform, we can easily download .NET Core SDK installer by clicking the Download .NET Core SDK button and beginning setup. Once setup finishes, you're ready to develop/run .NET Core applications on the machine.

• Installation for Linux:
  On the Linux platform, there are different commands to install .NET Core on Ubuntu, RedHat, Debian, Fedora, CentOS, and Suse distribution. We should select the correct distribution on the page, and execute some Terminal commands by following preceding instructions.

• Installation for macOS:
  On the macOS platform, it's as easy as downloading the .NET Core SDK package.

• Installation for Docker:
  There is another platform available to deploy and run .NET Core applications: Docker. Docker is simply a virtualization platform. You may run Docker on the machine and deploy your .NET Core applications into Docker. Once you successfully deploy an application to Docker, it's easy to run more than one instance of it.

Docker usually helps developers to scale their applications with minimum management cost.
