Note

Your feedback is highly valued. There are two ways you can provide feedback to the development team on Visual Studio for Mac:

  • In Visual Studio for Mac, select Help > Report a Problem from the menu or Report a Problem from the Welcome screen, which will open a window for filing a bug report. You can track your feedback in the Developer Community portal.
  • To make a suggestion, select Help > Provide a Suggestion from the menu or Provide a Suggestion from the Welcome screen, which will take you to the Visual Studio for Mac Developer Community webpage.

  2. A physical core is a group of transistors on a chip that implements a core. A logical core is something that appears to be a core to the operating system and user programs. In the vast number of cases, these are the same. However, Intel's Hyperthreading technology (and maybe others) makes each physical core appear as two logical cores.

The structure of the Mac OS X includes multiple layers. The base layer is Darwin which is the Unix core of the system. Next layer is the graphics system which contains Quartz, OpenGL and QuickTime.

Prerequisites

Mac OS, operating system (OS) developed by the American computer company Apple Inc. The OS was introduced in 1984 to run the company's Macintosh line of personal computers (PCs). The Macintosh heralded the era of graphical user interface (GUI) systems, and it inspired Microsoft Corporation to develop its own GUI, the Windows OS. I also tried with Mac OS X Snow Leopard (which is just one minor version above the one I had installed on the original drive, 10.5 Leopard) by dd'ing the boot disk into my USB drive and it does boot, but after 1 minute or so the apple symbol gets replaced with a prohibited symbol 🚫 and does nothing, even the disk activity LED stops blinking.

  • Visual Studio for Mac version 8.8 or later. Select the option to install .NET Core. Installing Xamarin is optional for .NET development. For more information, see the following resources:

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

Create the app

  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 5.0, 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

Install .NET On MacOS | Microsoft Docs

  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.

    NewLine is a platform-independent and language-independent way to represent a line break. Alternatives are n in C# and vbCrLf in Visual Basic.

    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. 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.
