Prerequisites

• Visual Studio for Mac version 8.6 or later. Select the option to install .NET Core. Installing Xamarin is optional for .NET Core development. For more information, see the following resources:

  • Tutorial: Install Visual Studio for Mac.
  • Supported macOS versions.
  • .NET Core versions supported by Visual Studio for Mac.

Create the app

Create a .NET Core console app project named 'HelloWorld'.

1. Start Visual Studio for Mac.

2. Select New in the start window.

3. In the New Project dialog, select App under the Web and Console node. Select the Console Application template, and select Next.

4. In the Target Framework drop-down of the Configure your new Console Application dialog, select .NET Core 3.1, and select Next.

5. Type 'HelloWorld' for the Project Name, and select Create.

The template creates a simple 'Hello World' application. It calls the Console.WriteLine(String) method to display 'Hello World!' in the terminal window.

The template code defines a class, Program, with a single method, Main, that takes a String array as an argument:

Main is the application entry point, the method that's called automatically by the runtime when it launches the application. Any command-line arguments supplied when the application is launched are available in the args array.

Run the app

1. Press ⌥⌘↵ (option+command+enter) to run the app without debugging.

2. Close the Terminal window.

Enhance the app

Enhance the application to prompt the user for their name and display it along with the date and time.

1. In Program.cs, replace the contents of the Main method, which is the line that calls Console.WriteLine, with the following code:

   This code displays a prompt in the console window and waits until the user enters a string followed by the enter key. It stores this string in a variable named name. It also retrieves the value of the DateTime.Now property, which contains the current local time, and assigns it to a variable named date. And it displays these values in the console window. Finally, it displays a prompt in the console window and calls the Console.ReadKey(Boolean) method to wait for user input.

   The n represents a newline character.

   The dollar sign ($) in front of a string lets you put expressions such as variable names in curly braces in the string. The expression value is inserted into the string in place of the expression. What's a good screenplay app for mac. This syntax is referred to as interpolated strings.

2. Press ⌥⌘↵ (option+command+enter) to run the app.

3. Respond to the prompt by entering a name and pressing enter.

4. Close the terminal.

Next steps

In this tutorial, you created a .NET Core console application. In the next tutorial, you debug the app.
