Developing with .NET Core

.NET Core applications can be developed with Visual Studio on the Windows platform and Visual Studio for Mac (inheriting from Xamarin Studio) on macOS. Visual Studio Code (an open source project) and Rider (JetBrain's development IDE) provide support for both of these platforms, as well as Unix-based systems. While these platforms provide the desired user-friendly development UI, technically, .NET core applications can be written with a simple text editor and compiled using the .NET Core command-line toolset:

As we mentioned previously, the only intrinsic runtime in the .NET Core CLI is the .NET Core runtime, which is primarily used for creating console applications with access to the complete base class library.

Without further ado, let's create our first cross-platform application with the CLI tools and see how it behaves on multiple target platforms.
