Note
Download Visual Studio for Mac. Create and deploy scalable, performant apps using.NET and C# on the Mac. Visual Studio 2019 for Mac. Develop apps and games for iOS, Android and using.NET. Download Visual Studio for Mac. ASP.NET Core and.NET Core Open-source.
I am building on a Windows 10 system, creating standalone builds in each case. I did get my app to run properly when I installed the.NET Core framework on the Mac (and built the app as a framework build), but I need to run standalone builds. I have installed OpenSSL on the Mac through Homebrew, which is the only external dependency I'm aware of.

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.
To download any other version of.NET Core, visit the dotnet page. When using.NET Core 3.0, C# version 8 will be used by default. C# 7.3 is default when using.NET Core 2.x. See C# language versioning for more info. For information on installing a preview version of Visual Studio for Mac, see the Install a Preview Release guide.
PrerequisitesVisual 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:

Create the appCreate a .NET Core console app project named 'HelloWorld'.
Start Visual Studio for Mac.
Select New in the start window.
In the New Project dialog, select App under the Web and Console node. Select the Console Application template, and select Next.
In the Target Framework drop-down of the Configure your new Console Application dialog, select .NET Core 3.1, and select Next.
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 appPress ⌥⌘↵ (option+command+enter) to run the app without debugging.
Close the Terminal window.

.net Core 2.1 Mac DownloadIn 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. This syntax is referred to as interpolated strings.
Press ⌥⌘↵ (option+command+enter) to run the app.
Respond to the prompt by entering a name and pressing enter.
Close the terminal.
