Register Microsoft key and feed
Before installing .NET, you’ll need to register the Microsoft key, register the product repository, and install required dependencies. This only needs to be done once per machine.
Open a terminal and run the following commands:

The dotnet command creates a new application of type console for you. The -o parameter creates a directory named myFirstApp where your app is stored, and populates it with the required files. The cd myFirstApp command puts you into the newly created app directory.

teddy@teddy:~/Documents/dotnet$ cd myFirstApp/ |
The main file in the myFirstApp folder is Program.cs. By default, it already contains the necessary code to write “Hello World!” to the Console.

Run your app
In your terminal, run the following command:

teddy@teddy:~/Documents/dotnet/myFirstApp$ dotnet run Hello World! |
Congratulations, you’ve built and run your first .NET app!
Edit your code
Open Program.cs in any text editor (e.g. Notepad) and add a new line of code below the one that prints “Hello World!”, like the following:
|
