Visual Studio Code supports macOS, Linux, and Windows - so you can hit the ground running, no matter the platform. Edit, build, and debug with ease. At its heart, Visual Studio Code features a lightning fast source code editor, perfect for day-to-day use. Microsoft’s Visual Studio Code is an excellent C development environment, and now it’s an easy install on Raspberry Pi. Here’s Jim Bennett from Microsoft to show you all how to get VS Code up and running on our tiny computer. Take it away, Jim There are a few products in.

Debugging .NET apps running on ARM-based IoT devices like Raspberry Pi presents a unique challenge. It is possible to develop .NET apps on ARM devices. However, OmniSharp, which is required for debugging .NET apps outside of Visual Studio, is not compatible with ARM devices. As a result, apps must be debugged remotely from a compatible platform.

Debug from Visual Studio Code (cross-platform)

Debugging .NET on Raspberry Pi from Visual Studio Code requires configuration steps on the Raspberry Pi and in the project's launch.json file.

Enable SSH on the Raspberry Pi

SSH is required for remote debugging. To enable SSH, refer to Enable SSH in the Raspberry Pi documentation.

Install the Visual Studio Remote Debugger on the Raspberry Pi

Within a Bash console on the Raspberry Pi (either locally or via SSH), complete the following steps:

1. Execute the following command to download and install the Visual Studio Remote Debugger on the Raspberry Pi:

2. The debugger requires running as root. By default, root has no password on Raspberry Pi. Set a password for root by executing the following command and following the prompts.

3. Visual Studio Code uses the SSH protocol to debug remotely. For security purposes, root is not permitted to log on via SSH by default. To enable root to log on via SSH, complete the following steps:

   1. Execute the following command to open /etc/ssh/sshd_config in nano.

   2. Press Ctrl+W and search for PermitRootLogin.

   3. Uncomment the line with PermitRootLogin if needed.

   4. Change the line to read as follows:

      Note

      If there is no PermitRootLogin line in /etc/ssh/sshd_config, add a new line with the value shown above.

   5. Press Ctrl+X to exit and save your chances. When prompted Save modified buffer?, press Y to confirm. Press Enter to confirm overwriting the original file.

   6. Reboot the Raspberry Pi by executing the following command:

Setup launch.json in Visual Studio Code

Add a launch configuration to the project's launch.json. If the project doesn't have a launch.json file, add one by switching to the Run tab, selecting create a launch.json file, and selecting .NET or .NET Core in the dialog.

The new configuration in launch.json should look similar to this:

Notice the following:

• program is the path to the .NET runtime on the Pi.
• args is the path to the assembly to debug on the Pi.
• cwd is the working directory to use when launching the app on the Pi.
• pipeProgram is the path to an SSH client on the local machine.
• pipeArgs are the parameters to be passed to the SSH client. Be sure to specify the password parameter, as well as the root user in the format <user>@<hostname>.

Important

The above example uses plink, a component of the PuTTY SSH client. OpenSSH, which is included in recent versions of Windows and Linux, may be used instead. However, OpenSSH doesn't support sending passwords as a command-line parameter. To use OpenSSH, configure your Raspberry Pi for passwordless SSH access.

Deploy the app

Visual Studio Code Ssh Raspberry Pi 4

Deploy the app as described in Deploy .NET apps to Raspberry Pi. Ensure the deployment path is the same path specified in the cwd parameter in the launch.json configuration.

Launch the debugger

On the Run tab, select the .NET Core Launch (remote console) configuration and select Start Debugging. The app launches on the Raspberry Pi. The debugger may be used to set breakpoints, inspect locals, and more.

Visual Studio can debug .NET apps on remote devices via SSH. No specialized configuration is required on the device. For details on using Visual Studio to debug .NET remotely, see Remote debug .NET on Linux using SSH.

The Raspberry Pi foundation has published a new article to its blog today, providing information on how to code remotely using your Raspberry Pi and the Visual Studio Code application. Earlier this month a Raspberry Pi supported version of the excellent Visual Studio Code software was made available for the Raspberry Pi mini PC by Microsoft.

If you like to run your Raspberry Pi as a ‘headless’ device to control various electronics, the new article provides everything you need to know about coding your Pi mini PC remotely using VS Code. Ashley Whittaker explains more over on the official Raspberry Pi blog.

“Visual Studio Code, or VS Code, is a free, open source, developer’s text editor with a whole swathe of extensions to support you coding in multiple languages, and provide tools to support your development. I practically live day to day in VS Code: whether I’m writing blog posts, documentation or Python code, or programming microcontrollers, it’s my work ‘home’. You can run VS Code on Windows, macOS, and of course on a Raspberry Pi.

Visual Studio Code Remote Ssh Raspberry Pi Zero

One of the extensions that helps here is the Remote SSH extension, part of a pack of remote development extensions. This extension allows you to connect to a remote device over SSH, and run VS Code as if you were running on that remote device. You see the remote file system, the VS Code terminal runs on the remote device, and you access the remote device’s hardware. When you are debugging, the debug session runs on the remote device, but VS Code runs on the host machine.”
