Get Started with Visual C++ for Linux Development
Setting up your project for Linux Development
With this extension you can author C++ code for Linux servers, desktops and devices. You can manage your connections to these machines from within VS. VS will automatically copy and remote build your sources and can launch your application with the debugger. Our project system supports targeting specific architectures, including ARM.

As of November of 2016 the Extension Gallery does not have a comments section anymore. Please use our support email or our github page to start a discussion and report issues.
This extension is no longer supported in Visual Studio 2015. It can still be installed by won't be updated further. This extension was integrated into Visual Studio 2017, which can be installed from https://www.visualstudio.com/downloads/. Once installed, you can install Visual C++ for Linux Development by selecting the "Linux development with C++" workload.
- This extension won't receive further updates in Visual Studio 2015. We integrated all the capabilities of the extension into Visual Studio 2017, where we also made considerable updates, and added major new features. Linux will continue to be a considerable investment for us, with the development focused in Visual Studio 2017. See above for more details. If you have any concerns or questions, you can open an issue for us, to start a discussion, at https://github.com/Microsoft/VSLinux/issues, or you can write us at email@example.com.

Create a Linux Project
After installing the extension to get started create a new project by going to Templates > Visual C++ > Cross Platform > Linux.
Connecting to Linux
Today we only support building remotely on the Linux target machine. We are not limited by specific Linux distros but we do have dependencies on the presence of some tools. Specifically, we need openssh-server, g++, gdb and gdbserver. Use your favorite package manager to install them, e.g. on Debian based systems: sudo apt-get install openssh-server g++ gdb gdbserver
The first time you target a Linux machine you will be prompted for connection information. This is triggered by building the project.
Adding and removing connections
To add a new connection, go to Tools > Options and search for Linux. You can also search Linux in the qucik launch box. From here you can add and remove connections.
To change which connection a project is using go to the project properties remote settings and update the target machine.
All of the options necessary to control C++ compilation are exposed on the project properies pages. We'll cover a few specific to how things work for Linux. First under remote settings, you will see the remote root is set to ~/projects/ by default and that we are setting the remote project directory to match our project name in that location.
Looking at the General settings for the project, you can see how our output and intermediate directories are configured. By default a project configured as an application will result in an executable under bin/x64/Debug/ under the project directory location. Notice that for configuration types we also support static and dynamic libraries.
Add additional library dependencies on the Linker > Input property page.
You can pass additional pre launch commands to the debugger to do things like launch graphical apps on the remote linux machine.
You can also send post build events to control remote behavior, as in this example that exports a gpio pin for use without requiring the executable run as super user.
