Coding .NET apps directly on a Raspberry Pi is slow and frustrating. There’s a much better way to work.
With tens of millions of Raspberry Pi devices now used in projects across the US, developers need an efficient workflow. The modern solution is remote development. You use the full power of your Windows PC and Visual Studio Code to write and debug code that runs live on the Pi.
It’s the best of both worlds: a powerful coding environment and a real-world test device.
This guide is a step-by-step tutorial for US developers. We’ll show you how to set up this powerful remote workflow, so you can stop waiting for your Pi to compile and start building amazing IoT projects.

The Architecture of Remote Development with VS Code
When you use Visual Studio Code for remote development, you’re not just editing files on another machine. In September 2025, this powerful feature uses a true client-server model that intelligently splits the work between your local computer and the remote device. This is what makes the experience so fast and seamless.
How It Works: A Smart Two-Part System Raspberry Pi
VS Code’s remote development isn’t magic; it’s a clever system with two main parts:
- On Your Main PC (The Client): You run the full, feature-rich VS Code application. It’s responsible for the beautiful, responsive user interface you know and love.
- On Your Remote Device (The Server): When you first connect, VS Code automatically installs a small, headless “VS Code Server.” This server does all the heavy lifting—accessing files, compiling your code, and running the debugger right on the target machine.
A secure SSH tunnel acts as the communication pipe between the two, sending your keystrokes to the server and the results back to your screen, making the whole experience feel like you’re working locally.
Why This is So Much Better Than the Old Ways
This client-server model is a huge improvement over older, clunkier methods for remote access.
- It’s Not a Laggy Remote Desktop (VNC/RDP): Unlike remote desktop software that streams the entire screen and forces you to run your code editor on the weak remote machine, VS Code keeps the UI on your fast, powerful computer.
- It’s Not Just a Remote File Editor (SSHFS): Unlike just editing remote files, which still forces you to use a separate terminal to compile and debug, VS Code integrates everything into one unified interface.
The Big Win: The Right Machine for the Right Job
The genius of this model is that it assigns each task to the machine that’s best suited for it. Your powerful PC handles the smooth UI, while the Raspberry Pi handles the code execution in its native environment.
This also gives you perfect development environment isolation. Your main computer stays clean—you don’t have to install any special toolchains or SDKs for the remote device. The entire build environment lives self-contained on the remote machine, which is a core principle of modern DevOps.
Core Features and Capabilities of the Remote Debugging Workflow
The client-server architecture of VS Code’s remote development enables a set of powerful features that make working on a remote device like a Raspberry Pi feel just like working on your local machine. In September 2025, the goal is a seamless, “frictionless” workflow, and this is how VS Code delivers it.
The “F5 Experience”: One-Click Build and Debug
The most powerful feature of this workflow is the “F5 Experience.” This is the ability to press a single key (F5) in VS Code on your main computer and have everything else happen automatically.
The IDE will compile your code, securely copy the files to the Raspberry Pi, launch the application, and attach the remote debugger—all in one seamless step. This completely eliminates all the tedious and error-prone manual command-line work (like using scp to copy files) and lets you stay focused on coding.
Full-Featured Remote Debugging, Not a Limited Version
This isn’t a watered-down version of a debugger. You get the full, high-fidelity experience you’re used to when working locally. You can:
- Set breakpoints to pause your code at any line.
- Step through your code line by line to see what’s happening.
- Inspect the values of all your variables and view the full call stack.
- Use advanced features like conditional breakpoints to hunt down complex bugs.
A Truly Unified Workspace
Beyond just debugging, the Remote-SSH extension deeply integrates the entire remote environment into your local VS Code window.
- Remote Files, Local Feel: Your Raspberry Pi’s file system appears right in the VS Code Explorer pane. You can create, edit, and delete remote files just as if they were on your own computer.
- An Integrated SSH Terminal: The terminal panel in VS Code becomes a real SSH shell on the Pi. You can run Linux commands and manage the device without ever needing to open a separate app like PuTTY.
- Smart Extension Management: The system is smart about where it installs your extensions. UI extensions like themes run locally, while language-specific tools like linters are automatically installed on the remote VS Code Server. It puts the tools right where they need to be.
The Bottom Line: Blurring the Line Between Local and Remote
The result of all these features is a development experience that masterfully blurs the line between local and remote. The physical distance to your Raspberry Pi is completely abstracted away, letting you focus all your brainpower on writing great code. Best of all, the skills you learn here are directly transferable to working with cloud servers, Docker containers, and the Windows Subsystem for Linux (WSL).
A Comprehensive Guide to Implementation
Getting the one-click “F5” remote debugging experience for .NET on a Raspberry Pi can be tricky, but it’s totally worth the effort. In September 2025, this setup is the key to a productive workflow. Here’s a comprehensive, step-by-step guide with the code details you’ll need.
Phase 1: Getting Your Gear Ready
Before you start, make sure you have the basics in place.
- On Your Windows PC: You’ll need VS Code with the official C# and Remote Development extensions installed from the Marketplace.
- On Your Raspberry Pi: You need a newer model (like a Pi 2 or later) running a 64-bit version of Raspberry Pi OS. The full debugging experience only works on a 64-bit system. You also need the .NET SDK for ARM installed on the Pi.
- On Your Network: Both devices need to be on the same local network. It’s a very good idea to give your Pi a static IP address in your router settings so it doesn’t change and break your configuration.
Phase 2: Setting Up the Raspberry Pi
Next, you need to get your Pi ready to accept remote connections and run the debugger.
- Enable SSH: This is the first and most important step. Open a terminal on your Pi and enable and start the SSH service.
- Install the VS Remote Debugger: Run this simple curl command in your Pi’s terminal to download and install the vsdbg remote debugger:
Bash
curl -sSL https://aka.ms/getvsdbgsh | /bin/sh /dev/stdin -v latest -l ~/vsdbg - Set Up Passwordless SSH (Highly Recommended): To get that smooth, one-click experience, you need to set up key-based authentication. This lets your PC connect to your Pi securely without you having to type a password every single time.
Phase 3: Configuring VS Code (The Code Details)
This is where most people get stuck. All the magic happens in two JSON files inside a .vscode folder in your project’s root directory.
The tasks.json File: Automating Your Build and Deploy
This file tells VS Code how to build your app for the Pi and then copy the files over. The build-for-pi task compiles the code, and the deploy-to-pi task uses scp to send it to the Pi.
JSON
{
“version”: “2.0.0”,
“tasks”: [
{
“label”: “build-for-pi”,
“command”: “dotnet”,
“type”: “process”,
“args”: [
“publish”,
“-c”,
“Debug”,
“-r”,
“linux-arm64”,
“–self-contained”,
“false”
],
“problemMatcher”: “$msCompile”
},
{
“label”: “deploy-to-pi”,
“type”: “shell”,
“dependsOn”: “build-for-pi”,
“command”: “scp -r ${workspaceFolder}/bin/Debug/net8.0/linux-arm64/publish/* [email protected]:~/myapp”,
“problemMatcher”: []
}
]
}
The launch.json File: Connecting the Debugger
This file tells VS Code how to start the debugging session. It runs your deploy task first, then uses an SSH “pipe” to connect to the debugger on the Pi.
JSON
{
“version”: “0.2.0”,
“configurations”: [
{
“name”: “.NET Core Launch (remote)”,
“type”: “coreclr”,
“request”: “launch”,
“preLaunchTask”: “deploy-to-pi”,
“program”: “~/.dotnet/dotnet”,
“args”: [“~/myapp/myapp.dll”],
“cwd”: “~/myapp”,
“stopAtEntry”: false,
“console”: “internalConsole”,
“pipeTransport”: {
“pipeCwd”: “${workspaceFolder}”,
“pipeProgram”: “ssh”,
“pipeArgs”: [ “[email protected]” ],
“debuggerPath”: “~/vsdbg/vsdbg”
}
}
]
}
Understanding the launch.json Paths
The launch.json file is notoriously confusing because it mixes paths from your local Windows PC and the remote Pi. Here’s a quick guide to the most important settings:
- “program”: Path to the dotnet executable on the Pi.
- “args”: Path to your app’s main DLL file on the Pi.
- “cwd”: The working directory for your app on the Pi.
- “pipeProgram”: The command to run the SSH client on your local PC (e.g., ssh).
- “debuggerPath”: Path to the vsdbg file you installed on the Pi.
Getting these paths right is the key to making the whole system work.
Table: Key launch.json Parameters for Remote Debugging Explained
| Parameter | Context | Description | Example |
| type | VS Code | Specifies the debugger type. Must be coreclr for.NET. | “coreclr” |
| request | VS Code | The debugger action. Must be launch to start a new process. | “launch” |
| preLaunchTask | VS Code | The name of a task in tasks.json to run before debugging (e.g., build and deploy). | “deploy-to-pi” |
| program | Remote (Pi) | Path to the executable on the Pi. For framework-dependent, this is dotnet. For self-contained, it’s the app executable. | “~/.dotnet/dotnet” |
| args | Remote (Pi) | Arguments for the program. For framework-dependent, this is the path to your app’s DLL. | [“~/myapp/myapp.dll”] |
| cwd | Remote (Pi) | The working directory for the application on the Pi. | “~/myapp” |
| pipeTransport | VS Code | The block that defines the SSH connection transport. | {…} |
| pipeProgram | Local (Win) | Path to the SSH client executable on your Windows machine. | “C:\\Windows\\System32\\OpenSSH\\ssh.exe” |
| pipeArgs | Local (Win) | Arguments for the SSH client, including the user and hostname of the Pi. | [“[email protected]”] |
| debuggerPath | Remote (Pi) | Path to the vsdbg executable on the Pi that was installed earlier. | “~/vsdbg/vsdbg” |
A Critical Review: Community Insights and Practical Realities
The official guides make remote debugging with VS Code look like magic. But what’s it really like to set up and use every day? In September 2025, the developer community on forums like Reddit has a clear and consistent message: the setup is a frustrating journey, but the destination is worth it. Let’s look at the real-world insights.
The Common Pain Points: Getting to “F5” is a Grind
While the end result is great, developers report several recurring challenges during the initial setup.
- The Configuration is a Nightmare: This is the number one complaint. Manually creating the launch.json and tasks.json files is confusing and error-prone. The mix of local and remote paths is a huge hurdle for many developers, and a single misplaced character can lead to cryptic errors.
- The C# Tooling Can Be Slow: The C# language support in VS Code (powered by a tool called OmniSharp) is functional, but many developers find it slower and less reliable than the tools in a full IDE like Visual Studio or JetBrains Rider.
- It’s an Editor, Not a Full IDE: VS Code is a fantastic code editor, but it’s missing some of the advanced, integrated tools (like performance profilers and unit test runners) that professional .NET developers are used to in a full-featured Integrated Development Environment (IDE).
The Verdict: A Tale of Two Experiences
The community’s view on this workflow is a tale of two distinct phases:
- During Setup: The experience is often described as “frustrating” and “tedious.”
- After Setup: Once it’s finally working and you can press F5 to deploy and debug, the sentiment changes completely. Developers call the result “amazing” and “a massive productivity enhancement.”
The Hidden Strength in the Struggle: Here’s the interesting part. The very thing that makes the setup so hard—the text-based launch.json and tasks.json files—is also a huge advantage for teams. These files can be committed to your Git repository. This is “Configuration as Code.” A senior developer can perfect the setup once, and the rest of the team can get the exact same working environment just by cloning the project. This turns a personal frustration into a powerful tool for team consistency.
A Comparative Analysis of Alternative Workflows
While VS Code’s Remote-SSH workflow is a fantastic and free option, it’s not the only way to develop remotely. In September 2025, there are several powerful alternatives, each with its own trade-offs in terms of cost, features, and ease of use. Let’s compare the main contenders.
VS Code vs. Full Visual Studio
This is a classic choice between a lightweight code editor and a full-featured Integrated Development Environment (IDE).
- Ease of Setup: Visual Studio wins here. With extensions, it offers a graphical, wizard-based setup that’s much easier than manually editing VS Code’s configuration files.
- Features: Visual Studio is a full-featured IDE, with a more powerful debugger and superior C# code intelligence (IntelliSense). It’s a heavyweight tool with more built-in power.
- The Trade-Offs: But that power comes at a cost. Visual Studio is heavy, resource-intensive, and Windows-only. VS Code is lightweight, completely free, and runs everywhere (Windows, macOS, and Linux).
VS Code vs. JetBrains Rider
JetBrains Rider is the premium, cross-platform IDE that many professional .NET developers swear by.
- Features and Productivity: Many pro developers argue that Rider provides the best overall C# development experience, with industry-leading code analysis and refactoring tools that can significantly boost productivity.
- Cross-Platform Power: Rider’s biggest advantage over Visual Studio is that it offers the exact same, powerful experience on Windows, macOS, and Linux.
- The Trade-Off: The main drawback is the cost. Rider is a premium, paid subscription product, while VS Code is free.
VS Code vs. Remote Desktop (VNC/RDP)
This comparison is about a purpose-built development tool vs. a generic remote access solution.
VS Code is far more efficient. It only sends the necessary data (like text and debug commands) over the network, making it fast and responsive. VNC streams the entire graphical desktop of the remote device, which is bandwidth-intensive and often laggy, especially over Wi-Fi.
A huge advantage for VS Code is that it can connect to “headless” devices—like a server or a Raspberry Pi without a monitor—that don’t even have a desktop environment running.
Table: Feature and Workflow Comparison of Development Environments
| Feature | Visual Studio Code | Visual Studio (Community) | JetBrains Rider |
| Cost | Free & Open Source | Free (with license restrictions) | Paid Subscription |
| Platform Support | Windows, macOS, Linux | Windows Only | Windows, macOS, Linux |
| Resource Usage | Lightweight | Heavy / “Bloated” | Heavy, high RAM usage |
| Remote Setup | Manual (JSON files), high complexity | Wizard-driven (with extensions), low complexity | Integrated, moderate complexity |
| Debugging Power | Very Good (MI Engine) | Excellent (Mature VS Debugger) | Excellent |
| C# IntelliSense | Good (OmniSharp) | Excellent (Roslyn) | Excellent (ReSharper Engine) |
| Refactoring Tools | Basic | Very Good | Industry-Leading |
| Extensibility | Massive Ecosystem | Strong Ecosystem | Strong Ecosystem |
| Team Workflow | Excellent (Version-controlled setup) | Good (Shared settings) | Excellent (Shared settings) |
Recommendations and “Best For” Scenarios
So, after comparing all the options, which remote development setup is right for you in September 2025? The best choice depends on who you are, what you’re working on, and your budget. Here are our final recommendations for three different types of developers.
For the Hobbyist, Student, or Prototyper: Visual Studio Code
If you’re working on a personal project, learning C#, or just building a prototype, the answer is clear: Visual Studio Code. The most important factor is that it’s completely free. While the initial setup can be a challenge, it’s a great hands-on learning experience. Its lightweight, cross-platform nature makes it the perfect choice when you don’t need the heavyweight features of a full IDE.
For the Professional .NET Developer on Windows: Visual Studio
In a professional environment where time is money, the path of least resistance is often the best one. For teams developing on Windows, Visual Studio is the top choice. It offers the easiest setup and the most mature, feature-rich .NET development experience. The productivity gains from its superior debugger and advanced tooling will quickly pay for themselves. It’s the natural choice for any business already invested in the Microsoft ecosystem.
For the Cross-Platform Power User: JetBrains Rider
For professional developers who demand the absolute best tools, work across different operating systems, or switch between multiple languages, JetBrains Rider is the premier choice. Its biggest advantage is providing the exact same, high-quality experience on Windows, macOS, and Linux. The paid subscription is justified by its best-in-class code analysis and refactoring tools, which can dramatically speed up development on large, complex applications.
Conclusion
Remote debugging .NET on a Raspberry Pi with VS Code is a powerful, no-cost option for developers. It automates your workflow and improves productivity. This setup offers great flexibility. However, it requires a complex manual configuration.
Paid tools like Visual Studio or Rider offer a more guided experience. The best tool depends on your budget, team skills, and project goals. VS Code is a strong choice for those who need a flexible and affordable solution.
