Others are hidden in the system's CoreServices folder. The CoreServices folder is located in the Macintosh HD System Library folder, and contains a number of applications, background tasks, and shared resources that the system uses to provide various services to the user.
This document provides the steps and workflow to create a .NET Core solution for macOS. Learn how to create projects, unit tests, use the debugging tools, and incorporate third-party libraries via NuGet.
Note
This article uses Visual Studio Code on macOS.
- A few months ago, I had a crash involving iTunes from which I could recover after the usual fsck at restart. However, one thing would not come back: 1.4Gb of my hard disk seemed to be lost. I tried many attempts with Norton Disk Doctor, File Buddy, etc., to locate new files and solve the issue.
- I need a way to get a machine's MAC address regardless of the OS it is running using C#. Application will need to work on XP/Vista/Win7 32 and 64 bit as well as on those OSs but with a foreign language default.
Prerequisites
Install the .NET Core SDK. The .NET Core SDK includes the latest release of the .NET Core framework and runtime.
Install Visual Studio Code. During the course of this article, you also install Visual Studio Code extensions that improve the .NET Core development experience.
Install the Visual Studio Code C# extension by opening Visual Studio Code and pressing Fn+F1 to open the Visual Studio Code palette. Type ext install to see the list of extensions. Select the C# extension. Restart Visual Studio Code to activate the extension. For more information, see the Visual Studio Code C# Extension documentation.
Get started
In this tutorial, you create three projects: a library project, tests for that library project, and a console application that makes use of the library. You can view or download the source for this article at the dotnet/samples repository on GitHub. For download instructions, see Samples and Tutorials.
Start Visual Studio Code. Press Ctrl` (the backquote or backtick character) or select View > Terminal from the menu to open an embedded terminal in Visual Studio Code. You can still open an external shell with the Explorer Open in Command Prompt command (Open in Terminal on macOS or Linux) if you prefer to work outside of Visual Studio Code.
Begin by creating a solution file, which serves as a container for one or more .NET Core projects. In the terminal, run the
dotnet new
command to create a new solution golden.sln inside a new folder named golden:How To Get To Core Services Library On Mac Free
Navigate to the new golden folder and execute the following command to create a library project, which produces two files,library.csproj and Class1.cs, in the library folder:
Execute the
dotnet sln
command to add the newly created library.csproj project to the solution:The library.csproj file contains the following information:
Our library methods serialize and deserialize objects in JSON format. To support JSON serialization and deserialization, add a reference to the
Newtonsoft.Json
NuGet package. The dotnet add
command adds new items to a project. To add a reference to a NuGet package, use the dotnet add package
command and specify the name of the package:This adds
Newtonsoft.Json
and its dependencies to the library project. Alternatively, manually edit the library.csproj file and add the following node:Execute
dotnet restore
, (see note) which restores dependencies and creates an obj folder inside library with three files in it, including a project.assets.json file:Mac photos library always stuck on closing the library. In the library folder, rename the file Class1.cs to Thing.cs. Replace the code with the following:
The
Thing
class contains one public method, Get
, which returns the sum of two numbers but does so by converting the sum into a string and then deserializing it into an integer. This makes use of a number of modern C# features, such as using static
directives, expression-bodied members, and string interpolation.Build the library with the
dotnet build
command. This produces a library.dll file under golden/library/bin/Debug/netstandard1.4:Create the test project
How To Get To Core Services Library On Mac Computer
Build a test project for the library. From the golden folder, create a new test project:
Add the test project to the solution:
Add a project reference the library you created in the previous section so that the compiler can find and use the library project. Use the
dotnet add reference
command:Alternatively, manually edit the test-library.csproj file and add the following node:

Now that the dependencies have been properly configured, create the tests for your library. Open UnitTest1.cs and replace its contents with the following code:
Note that you assert the value 42 is not equal to 19+23 (or 42) when you first create the unit test (
Assert.NotEqual
), which will fail. An important step in building unit tests is to create the test to fail once first to confirm its logic.![Get Get](https://i.stack.imgur.com/6UcWC.png)
From the golden folder, execute the following commands:
These commands will recursively find all projects to restore dependencies, build them, and activate the xUnit test runner to run the tests. https://gamblingclever125.weebly.com/how-to-use-multiple-photo-libraries-on-a-mac.html. The single test fails, as you expect.
Edit the UnitTest1.cs file and change the assertion from
Assert.NotEqual
to Assert.Equal
. Execute the following command from the golden folder to re-run the test, which passes this time:Create the console app
The console app you create over the following steps takes a dependency on the library project you created earlier and calls its library method when it runs. Using this pattern of development, you see how to create reusable libraries for multiple projects.
Create a new console application from the golden folder:
Add the console app project to the solution:
Create the dependency on the library by running the
dotnet add reference
command:Run
dotnet restore
(see note) to restore the dependencies of the three projects in the solution. Open Program.cs and replace the contents of the Main
method with the following line:Add two
using
directives to the top of the Program.cs file:Execute the following
dotnet run
command to run the executable, where the -p
option to dotnet run
specifies the project for the main application. The app produces the string 'The answer is 42'.Debug the application
Set a breakpoint at the
WriteLine
statement in the Main
method. Do this by either pressing the Fn+F9 key when the cursor is over the WriteLine
line or by clicking the mouse in the left margin on the line where you want to set the breakpoint. A red circle will appear in the margin next to the line of code. When the breakpoint is reached, code execution will stop before the breakpoint line is executed.Open the debugger tab by selecting the Debug icon in the Visual Studio Code toolbar, selecting View > Debug from the menu bar, or using the keyboard shortcut ⇧⌘D:
Press the Play button to start the application under the debugger. You've created both a test project and an application in this project. The debugger asks which project you want to start. Select the 'app' project. The app begins execution and runs to the breakpoint, where it stops. Step into the
Get
method and make sure that you have passed in the correct arguments. Confirm that the answer is 42.Note
Starting with .NET Core 2.0 SDK, you don't have to run
-->dotnet restore
because it's run implicitly by all commands that require a restore to occur, such as dotnet new
, dotnet build
and dotnet run
.It's still a valid command in certain scenarios where doing an explicit restore makes sense, such as continuous integration builds in Azure DevOps Services or in build systems that need to explicitly control the time at which the restore occurs.Visual Studio for Mac provides a full-featured Integrated Development Environment (IDE) for developing .NET Core applications. This article walks you through building a simple console application using Visual Studio for Mac and .NET Core.

Get started
If you've already installed the prerequisites and Visual Studio for Mac, skip this section and proceed to Creating a project. Follow these steps to install the prerequisites and Visual Studio for Mac:
Download the Visual Studio for Mac installer. Run the installer. Read and accept the license agreement. During the install, select the option to install .NET Core. You're provided the opportunity to install Xamarin, a cross-platform mobile app development technology. Installing Xamarin and its related components is optional for .NET Core development. For a walk-through of the Visual Studio for Mac install process, see Visual Studio for Mac documentation. When the install is complete, start the Visual Studio for Mac IDE.
Creating a project
- Select New on the start window.
- In the New Project dialog, select App under the .NET Core node. Select the Console Application template followed by Next.
- If you have more than one version of .NET Core installed, select the target framework for your project.
- Type 'HelloWorld' for the Project Name. Select Create.
- Wait while the project's dependencies are restored. The project has a single C# file, Program.cs, containing a
Program
class with aMain
method. TheConsole.WriteLine
statement will output 'Hello World!' to the console when the app is run.
Run the application
Run the app in Debug mode using ⌘ ↵ (command + enter) or in Release mode using ⌥ ⌘ ↵ (option + command + enter).
