I've lost count of how many times I've heard someone say "just open it in Visual Studio" when they meant VS Code. Or watched a junior dev download the full Visual Studio IDE when all they needed was to edit a JavaScript file.
These are not the same product. The naming is Microsoft's fault, not yours. But let's clear this up once and for all.
The Short Version
Visual Studio is a full integrated development environment (IDE). It's massive, feature-rich, and designed for building complex applications—think enterprise .NET projects, C++ game development, or large-scale software with multiple developers.
Visual Studio Code is a lightweight source code editor. It's fast, flexible, and extensible. You can make it do almost anything through extensions, but out of the box it's intentionally minimal.
Same family name. Completely different animals.
When to Use Visual Studio (the big one)
I reach for Visual Studio when I'm working on something that genuinely needs the horsepower. A .NET application with dozens of projects. Anything involving deep debugging with breakpoints across multiple threads. Mobile development with Xamarin or MAUI. Game development in C++ or with Unity integration that benefits from the tighter tooling.
Visual Studio comes with built-in support for compiling, advanced debugging, profiling, database tools, designers for UI, and team collaboration features. It understands your entire solution architecture. When you're building something complex in the Microsoft ecosystem, that integration isn't just convenient—it's the whole point.
The trade-off? It's heavy. Startup times can test your patience. It wants a decent amount of RAM. And unless you're using the Community edition, it costs money.
When to Use VS Code (the fast one)
VS Code is my daily driver for almost everything else. Quick script edits. Web development. Python projects. Writing documentation. Anything where I want to open a folder, make changes, and get out without waiting for an IDE to wake up and index the known universe.
It launches in seconds. It runs on Windows, Mac, and Linux without complaint. The extension marketplace means I can bolt on support for basically any language or framework I encounter. And it's free—genuinely free, not "free until you need the useful features" free.
The catch is that VS Code doesn't inherently understand your project the way Visual Studio does. It's a really smart text editor with excellent extensions. Want IntelliSense for C#? Install an extension. Need debugging? Extension. Linting? Extension. It can absolutely handle serious development work, but you're assembling the experience yourself.
The Actual Differences That Matter
Size and performance: Visual Studio is multiple gigabytes installed and uses significant system resources. VS Code is a few hundred megabytes and stays light.
Built-in vs extensible: Visual Studio includes most of what you need out of the box for its target scenarios. VS Code assumes you'll customize it for your workflow.
Project model: Visual Studio works with solutions and projects with deep integration. VS Code works with folders and files—it's project-agnostic by design.
**Cost: **Visual Studio has paid tiers (Professional, Enterprise) with the free Community edition having some licensing restrictions for larger organizations. VS Code is free for everyone.
Platform: Visual Studio is Windows-first (there's a Mac version but it's a different product under the hood). VS Code runs identically everywhere.
My Setup
In today's age of cheap storage, I keep both installed. Visual Studio handles my .NET work where the integrated tooling genuinely saves time. VS Code handles everything else—and honestly, that's most of my day. Frontend work, scripting, config files, quick fixes, writing articles like this one.
There's no wrong answer here. Just different tools for different jobs. The only wrong move is assuming they're interchangeable because Microsoft couldn't resist putting "Visual Studio" in both names.
Now you know. Go forth and download the right one.
