- Today at the Microsoft Build conference, we announced the general availability of Visual Studio 2017 for Mac. Visual Studio for Mac is a full-featured IDE built natively for the Mac, to help you develop, debug, and test anything from mobile and web apps to games.
- 2020-3-23 Visual Studio Code is an editor while Visual Studio is an IDE. Visual Studio Code is cross-platform and fast, while Visual Studio is Windows/Mac only and not fast. Note that Visual Studio for Mac is available now but is a different product compared to Visual Studio (Windows).
- When you sign into Visual Studio Community, you get access to a broad set of free developer tools, selected Xamarin University courses on-demand, Pluralsight training, Azure credits, and more as part of Visual Studio Dev Essentials.
- Sep 21, 2016 But when I open the C project folder with Visual Studio Code, after I click the lightbulb to 'add include path to settings', it navigate to ccppproperties.json file and there has a 'includePath' setting in this file. Please add the additional include directories path in this setting.

.NET Core gives you a fast and modular platform for creating applications that run on Windows, Linux, and macOS. Use Visual Studio Code with the C# extension to get a powerful editing experience with full support for C# IntelliSense (smart code completion) and debugging.
Prerequisites
- Install Visual Studio Code.
- Install the .NET Core SDK.
- Install the C# extension for Visual Studio Code. For more information about how to install extensions on Visual Studio Code, see VS Code Extension Marketplace.
Hello World
Let's get started with a simple 'Hello World' program on .NET Core:
- Open a project:
- Open Visual Studio Code.
- Click on the Explorer icon on the left menu and then click Open Folder.
- Select File > Open Folder from the main menu to open the folder you want your C# project to be in and click Select Folder. For our example, we're creating a folder for our project named HelloWorld.
- Initialize a C# project:
- Open the Terminal from Visual Studio Code by selecting View > Terminal from the main menu.
- In the terminal window, type
dotnet new console
. - This command creates a Program.cs file in your folder with a simple 'Hello World' program already written, along with a C# project file named HelloWorld.csproj.
- Resolve the build assets:
- For .NET Core 1.x, type
dotnet restore
. Runningdotnet restore
gives you access to the required .NET Core packages that are needed to build your project.NoteStarting with .NET Core 2.0 SDK, you don't have to rundotnet restore
because it's run implicitly by all commands that require a restore to occur, such asdotnet new
,dotnet build
anddotnet 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.
- Run the 'Hello World' program:
- Type
dotnet run
.

Debug
- Open Program.cs by clicking on it. The first time you open a C# file in Visual Studio Code, OmniSharp loads in the editor.
- Visual Studio Code should prompt you to add the missing assets to build and debug your app. Select Yes.
- To open the Debug view, click on the Debugging icon on the left side menu.
- Locate the green arrow at the top of the pane. Make sure the drop-down next to it has .NET Core Launch (console) selected.
- Add a breakpoint to your project by clicking on the editor margin, which is the space on the left of the line numbers in the editor, next to line 9, or move the text cursor onto line 9 in the editor and press F9.
- To start debugging, press F5 or select the green arrow. The debugger stops execution of your program when it reaches the breakpoint you set in the previous step.
- While debugging, you can view your local variables in the top-left pane or use the debug console.
- Select the blue arrow at the top to continue debugging, or select the red square at the top to stop.
Tip
For more information and troubleshooting tips on .NET Core debugging with OmniSharp in Visual Studio Code, see Instructions for setting up the .NET Core debugger.
Add a class
- To add a new class, right-click in the VSCode Explorer and select New File. This adds a new file to the folder you have open in VSCode.
- Name your file MyClass.cs. You must save it with a
.cs
extension at the end for it to be recognized as a csharp file. - Add the code below to create your first class. Make sure to include the correct namespace so you can reference it from your Program.cs file:
- Call your new class from your main method in Program.cs by adding the code below:
- Save your changes and run your program again. The new message should appear with the appended string.You get the following output:
FAQ
I'm missing required assets to build and debug C# in Visual Studio Code. My debugger says 'No Configuration.'
The Visual Studio Code C# extension can generate assets to build and debug for you. Visual Studio Code prompts you to generate these assets when you first open a C# project. If you didn't generate assets then, you can still run this command by opening the Command Palette (View > Command Palette) and typing '>.NET: Generate Assets for Build and Debug'. Selecting this generates the .vscode, launch.json, and tasks.json configuration files that you need.

Visual Studio 2019 Installation
Welcome to Visual Studio 2019! In this version, it's easy to choose and install just the features you need. And because of its reduced minimum footprint, it installs quickly and with less system impact.
Note
This topic applies to installation of Visual Studio on Windows. Visual Studio Code is a lightweight, cross-platform development environment that runs on Windows, Mac, and Linux systems. The Microsoft C/C++ for Visual Studio Code extension supports IntelliSense, debugging, code formatting, auto-completion. Visual Studio for Mac doesn't support Microsoft C++, but does support .NET languages and cross-platform development. For installation instructions, see Install Visual Studio for Mac.
Want to know more about what else is new in this version? See the Visual Studio release notes.
Ready to install? We'll walk you through it, step-by-step.
Step 1 - Make sure your computer is ready for Visual Studio
Before you begin installing Visual Studio:
- Check the system requirements. These requirements help you know whether your computer supports Visual Studio 2019.
- Apply the latest Windows updates. These updates ensure that your computer has both the latest security updates and the required system components for Visual Studio.
- Reboot. The reboot ensures that any pending installs or updates don't hinder the Visual Studio install.
- Free up space. Remove unneeded files and applications from your %SystemDrive% by, for example, running the Disk Cleanup app.
For questions about running previous versions of Visual Studio side by side with Visual Studio 2019, see the Visual Studio 2019 Platform Targeting and Compatibility page.
Step 2 - Download Visual Studio
Next, download the Visual Studio bootstrapper file. To do so, choose the following button, choose the edition of Visual Studio that you want, choose Save, and then choose Open folder.
Step 3 - Install the Visual Studio installer
Run the bootstrapper file to install the Visual Studio Installer. This new lightweight installer includes everything you need to both install and customize Visual Studio.
- From your Downloads folder, double-click the bootstrapper that matches or is similar to one of the following files:
- vs_community.exe for Visual Studio Community
- vs_professional.exe for Visual Studio Professional
- vs_enterprise.exe for Visual Studio Enterprise
If you receive a User Account Control notice, choose Yes. - We'll ask you to acknowledge the Microsoft License Terms and the Microsoft Privacy Statement. Choose Continue.
Step 4 - Choose workloads
After the installer is installed, you can use it to customize your installation by selecting the workloads, or feature sets, that you want. Here's how.
- Find the workload you want in the Installing Visual Studio screen.For core C++ support, choose the 'Desktop development with C++' workload. It comes with the default core editor, which includes basic code editing support for over 20 languages, the ability to open and edit code from any folder without requiring a project, and integrated source code control.Additional workloads support other kinds of C++ development. For example, choose the 'Universal Windows Platform development' workload to create apps that use the Windows Runtime for the Microsoft Store. Choose 'Game development with C++' to create games that use DirectX, Unreal, and Cocos2d. Choose 'Linux development with C++' to target Linux platforms, including IoT development.The Installation details pane lists the included and optional components installed by each workload. You can select or deselect optional components in this list. For example, to support development by using the Visual Studio 2017 or 2015 compiler toolsets, choose the MSVC v141 or MSVC v140 optional components. You can add support for MFC, the experimental Modules language extension, IncrediBuild, and more.
- After you choose the workload(s) and optional components you want, choose Install.Next, status screens appear that show the progress of your Visual Studio installation.
Tip
At any time after installation, you can install workloads or components that you didn't install initially. If you have Visual Studio open, go to Tools > Get Tools and Features... which opens the Visual Studio Installer. Or, open Visual Studio Installer from the Start menu. From there, you can choose the workloads or components that you wish to install. Then, choose Modify.
Step 5 - Choose individual components (Optional)
If you don't want to use the Workloads feature to customize your Visual Studio installation, or you want to add more components than a workload installs, you can do so by installing or adding individual components from the Individual components tab. Choose what you want, and then follow the prompts.
Step 6 - Install language packs (Optional)
By default, the installer program tries to match the language of the operating system when it runs for the first time. To install Visual Studio in a language of your choosing, choose the Language packs tab from the Visual Studio Installer, and then follow the prompts.
Change the installer language from the command line
Another way that you can change the default language is by running the installer from the command line. For example, you can force the installer to run in English by using the following command:
vs_installer.exe --locale en-US
. The installer will remember this setting when it's run the next time. The installer supports the following language tokens: zh-cn, zh-tw, cs-cz, en-us, es-es, fr-fr, de-de, it-it, ja-jp, ko-kr, pl-pl, pt-br, ru-ru, and tr-tr.Step 7 - Change the installation location (Optional)
You can reduce the installation footprint of Visual Studio on your system drive. You can choose to move the download cache, shared components, SDKs, and tools to different drives, and keep Visual Studio on the drive that runs it the fastest.
Important
You can select a different drive only when you first install Visual Studio. If you've already installed it and want to change drives, you must uninstall Visual Studio and then reinstall it.
Step 8 - Start developing
- After Visual Studio installation is complete, choose the Launch button to get started developing with Visual Studio.
- On the start window, choose Create a new project.
- In the search box, enter the type of app you want to create to see a list of available templates. The list of templates depends on the workload(s) that you chose during installation. To see different templates, choose different workloads.You can also filter your search for a specific programming language by using the Language drop-down list. You can filter by using the Platform list and the Project type list, too.
- Visual Studio opens your new project, and you're ready to code!
Visual Studio 2017 Installation
In Visual Studio 2017, it's easy to choose and install just the features you need. And because of its reduced minimum footprint, it installs quickly and with less system impact.
Prerequisites
- A broadband internet connection. The Visual Studio installer can download several gigabytes of data.
- A computer that runs Microsoft Windows 7 or later versions. We recommend Windows 10 for the best development experience. Make sure that the latest updates are applied to your system before you install Visual Studio.
- Enough free disk space. Visual Studio requires at least 7 GB of disk space, and can take 50 GB or more if many common options are installed. We recommend you install it on your C: drive.
For details on the disk space and operating system requirements, see Visual Studio Product Family System Requirements. The installer reports how much disk space is required for the options you select.
Download and install
- Download the latest Visual Studio 2017 installer for Windows.TipThe Community edition is for individual developers, classroom learning, academic research, and open source development. For other uses, install Visual Studio 2017 Professional or Visual Studio 2017 Enterprise.
- Find the installer file you downloaded and run it. It may be displayed in your browser, or you may find it in your Downloads folder. The installer needs Administrator privileges to run. You may see a User Account Control dialog asking you to give permission to let the installer make changes to your system; choose Yes. If you're having trouble, find the downloaded file in File Explorer, right-click on the installer icon, and choose Run as Administrator from the context menu.
- The installer presents you with a list of workloads, which are groups of related options for specific development areas. Support for C++ is now part of optional workloads that aren't installed by default.For C++, select the Desktop development with C++ workload and then choose Install.
- When the installation completes, choose the Launch button to start Visual Studio.The first time you run Visual Studio, you're asked to sign in with a Microsoft Account. If you don't have one, you can create one for free. You must also choose a theme. Don't worry, you can change it later if you want to.It may take Visual Studio several minutes to get ready for use the first time you run it. Here's what it looks like in a quick time-lapse:Visual Studio starts much faster when you run it again.
- When Visual Studio opens, check to see if the flag icon in the title bar is highlighted:If it's highlighted, select it to open the Notifications window. If there are any updates available for Visual Studio, we recommend you install them now. Once the installation is complete, restart Visual Studio.
Visual Studio 2015 Installation
To install Visual Studio 2015, go to Download older versions of Visual Studio. Run the setup program and choose Custom installation and then choose the C++ component. To add C++ support to an existing Visual Studio 2015 installation, click on the Windows Start button and type Add Remove Programs. Open the program from the results list and then find your Visual Studio 2015 installation in the list of installed programs. Double-click it, then choose Modify and select the Visual C++ components to install.
In general, we highly recommend that you use Visual Studio 2017 even if you need to compile your code using the Visual Studio 2015 compiler. For more information, see Use native multi-targeting in Visual Studio to build old projects.
