The C# support in Visual Studio Code is optimized for cross-platform .NET Core development (see working with .NET Core and VS Code for another relevant article). Our focus with VS Code is to be a great editor for cross-platform C# development.
Visual Studio is an integrated development suite of productivity tools for developers. Think of it as a program you can use to create programs and applications. Congratulations on completing this tutorial! We hope you learned a little bit about C#, ASP.NET Core, and the Visual Studio IDE. C# (pronounced 'c-sharp') is a great coding language that works across Mac and PC. Programmers use it to build a variety of software applications, especially in the Windows environment.
VS Code supports debugging of C# applications running on either .NET Core or Mono.
For detailed instructions on:
Mar 10, 2008 I do.NET Core development at work on a Mac (that's all I have access to), and the biggest pain in the ass is not being able to test against IIS (which is what we deploy to) locally. If there was a way to work with that it wouldn't be so bad. The next largest pain in the ass is how shitty VS for Mac is compared to regular VS. Microsoft has released Visual Studio Code 2017. It works on Windows, Mac OS, and Linux; It is quite nice development text-editor. It works similar to the full-version, available on Windows - with a few draw-backs, and it will allow to write programs, as well as run and test them right on your Mac. SharpDevelop is the open-source IDE for the.NET platform. Write applications in languages including C#, VB.NET, F#, IronPython and IronRuby, as well as target rich and reach: Windows Forms or WPF, as well as ASP.NET MVC and WCF.
- .NET Core debugging - see the Microsoft C# extension's GitHub page.
- Mono debugging - see the Mono Debug extension's README.
Note:VS Code has limited support for debugging applications running on the Desktop .NET Framework.
Due to this focus, many standard C# project types are not recognized by VS Code. An example of a non-supported project type is an ASP.NET MVC Application (though ASP.NET Core is supported). In these cases, if you want to have a lightweight tool to edit a file - VS Code has you covered. If you want the best possible experience for those projects and development on Windows in general, we recommend you use Visual Studio Community.
Installing C# support
C# language support is an optional install from the Marketplace. You can install it from within VS Code by searching for 'C#' in the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)) or if you already have a project with C# files, VS Code will prompt you to install the extension as soon as you open a C# file.
Roslyn and OmniSharp
Visual Studio Code uses the power of Roslyn and OmniSharp to offer an enhanced C# experience. We offer support for:
- .NET Core projects
- MSBuild projects
- C# scripts (CSX)
Mac address bytes. On startup the best matching projects are loaded automatically but you can also choose your projects manually. The status bar will show what projects have been loaded and also allows you to select a different set of projects. To do so, click on the status bar projects item and select Change projects…. In the image below a single project has been picked up:
The available options include:
- Selecting a
project.jsonfile will open a .NET Core project and VS Code will load that project plus the referenced projects. - Selecting a
*.slnfile opens a MSBuild-project. It will load the referenced*.csprojprojects and sibling or descendantproject.jsonfiles but no other project files that are referenced from the solution file. - Selecting a
folderwill make VS Code scan for*.sln,project.jsonand*.csxfiles (C# scripts) and VS Code will attempt to load them all.
Once the project is loaded the enhanced experiences light up..
Editing Evolved
There is a lot to discover with C# and the editor, such as format on type, IntelliSense, the rename-refactoring, etc.
For a full description of our editing features, go to the Basic Editing and Code Navigation documentation.
Here are a few highlights..
C Sharp Development On Mac Air
IntelliSense
IntelliSense just works: hit ⌃Space (Windows, Linux Ctrl+Space) at any time to get context specific suggestions. Auto presser mac.
Snippets for C#
We have several built-in snippets included in VS Code that will come up as you type or you can press ⌃Space (Windows, Linux Ctrl+Space) (Trigger Suggest) and we will give you a context specific list of suggestions.
Tip: You can add in your own User Defined Snippets for C#. Take a look at User Defined Snippets to find out how.
Search for Symbols
There are also features outside the editor. One is the ability to search for symbols from wherever you are. Hit ⌘T (Windows, Linux Ctrl+T), start typing, and see a list of matching C# symbols. Select one and you'll be taken straight to its code location.
CodeLens
Another cool feature is the ability to see the number of references to a method directly above the method. Click on the reference info to see the references in the Peek view. This reference information updates as you type.
Note: Methods defined in object, such as equals and hashCode do not get reference information due to performance reasons.
Tip: You can turn off references information displayed in CodeLens with the editor.codeLenssetting.
Find References/Peek Definition
You can click on the references of an object to find the locations of its use in place without losing context. This same experience works in reverse where you can Peek the definition of an object and see it inline without leaving your location.
Quick Fixes / Suggestions
There are some basic quick fixes supported in VS Code. You will see a lightbulb and clicking on it, or pressing ⌘. (Windows, Linux Ctrl+.) provides you with a simple list of fixes/suggestions.

Common questions
My Project won't load
VS Code only supports a limited set of project types (primarily .NET Core). For full .NET project support, we suggest you use Visual Studio Community.
IntelliSense is not working
This is typically as a result of the current project type not being supported. You can see an indication in the OmniSharp flame in the bottom left hand side of the status bar.
How do I build/run my project?
VS Code supports tasks for build and natively understand the output of MSBuild, CSC, XBuild. Find out more in the Tasks documentation.
C Sharp On Mac
I'm missing required assets to build and debug C# in VS Code. My debugger says 'No Configuration'
The Visual Studio Code C# extension can generate the assets you need to build and debug. If you missed the prompt when you first opened a new C# project, you can still perform this operation through the Command Palette (View > Command Palette) by typing '.NET', and running .NET: Generate Assets for Build and Debug. This command will generate the necessary launch.json and tasks.json configuration files (under the .vscode folder).

What is Visual Studio for Mac?
'- Hi, I'm John. We're continuing our introduction to Visual Studio for Mac. And in this video, we are going to install Visual Studio for Mac and create a simple C# application. So, Visual Studio for Mac is part of the Visual Studio family. I've gone to the Visual Studio website, visualstudio.com, and I click Download Visual Studio for Mac. And so then, while it's installing, there's a few steps to this. First, it downloads this kind of quick installer. It does a little verification step. And then after that, it's going to allow me to select what I'm installing. So here, I'm going to click on the little green down arrow and that's going to pop up the full installer. So again, we need to go through this verification step, and then it's going to allow me to pick which workloads I'd like to support. So there's a small trade off here. I can decide to install everything up front just in case I'll use it later. Or I may say I want to just use .NET Core development, which is what I'm going to do today. So if you do later say, Oops, I actually would have liked to install support for mobile development or for games, I can go back through and install additional support later. So here it's completing the verification. I'm going to open this. So you just verify, yes, I did actually download this on purpose and now it's going to walk me through installing. So it's doing some, you know, some magic. It's checking to see what all is installed. It's also, you know, I need to say, Yes, I accept the terms. So this is the point where I was mentioning, I can go through and I can say, What exactly do I want to build? So if you are going to be building, for instance, Mac OS applications or iOS applications, you can leave that checked. In order to speed up this install, you can just select .NET Core, which is what we'll do today. So now I'm going to click install. And at this point, it's got to download a few hundred megabytes and go through this installation process. So while it's doing that, let me show you some other resources that were displayed on this page. So once I've clicked on this, on downloaded and it says, thank you. Here's some other stuff. If you're like me, and I know I am, I often just ignore these pages, close the tabs and move on, but there's actually some really good information here. So if you click on this Get Started, this takes you through, here's our tailored experience. Here's what we think you should know if you're getting started with Visual Studio for Mac. So it has this whole document on installation if you run into any trouble. There's also this Take a Tour of Visual Studio for Mac, and this talks about what all you can do in more time than we're going to talk today. And it walks you through the setup experience. It walks you through all the different things that are available there. So this is a really good resource as you're getting set up with Visual Studio for Mac. So let's go take a look. It's going through and it's doing my installation. And so I probably have just a few more minutes left. Okay. So our installation completed. So I can go ahead and eject this and we are ready to get started. So, now that we have installed Visual Studio for Mac, I can go and create a new project. So we're going to start with the simplest kind, which is a console application. So I'm going to go in here and I'm going to say I would like to create a .NET Core app with the console application. Click next. I can give it a name, and then I can decide what other things I want to do, if I want to use version control, et cetera. So I think it's a good practice, usually, I just go ahead and create those by default. So now it's going to create a new application for me. And that's one of the nice things that an IDE, an integrated development environment, like this does, is actually create new project types for me. So it'll get things set up and running. Okay. So here is our console application. So this is a very simple application. When I run it, it's just going to say, 'Hello world.' So let's make sure that works. So it's going to build that and it's going to run it. And there we go. And it said, 'Hello world,' and press any key to continue. And now that I've got this set up, I can go in and I can edit it. I can, first of all, I'll stop debugging. So now, if I wanted, I can continue to use any of the features that we've talked about in the previous videos. We can go in here and I can do refactoring, I can, you know, set a debugger. All this kind of stuff and I can just get right to work. So a console application is great for just learning the language features, especially. It's very lightweight, not a lot of code and very interactive. So we've just finished working on a very simple application. As you're building more complex applications, you're going to want to take advantage of the more advanced features in Visual Studio for Mac. So be sure and join us in our next video when we're going to be looking at some productivity features and tips and tricks for Visual Studio for Mac.
