求Ubuntu平台下轻量且高质量的原生C#/C++ IDE（替代Visual Studio）

Hey there! Since you've spent two years with Visual Studio on Windows and are now making the switch to Ubuntu, I’ve got some solid native IDE recommendations that fit your requirements perfectly—no huge 5GB+ downloads, no Wine workarounds, and options ranging from full-featured to lightweight.

1. Rider (JetBrains) #

• While JetBrains tools are known for robust feature sets, you don’t need to download a massive full package to try Rider. Grab the JetBrains Toolbox (only a few hundred MBs), install it, and then you can launch a full-featured trial of Rider directly—Toolbox will download only the necessary components on demand, keeping the initial download way under 5GB.
• It’s fully native to Linux, offers top-tier support for both C# and C++, with smart IntelliSense, powerful refactoring tools, and a UI that feels familiar if you’re coming from VS. Startup times are snappier than Visual Studio, and the learning curve is gentle.

2. Code::Blocks #

• A fully native Linux IDE built primarily for C++, but it supports C# via easy-to-install plugins. The installation package is tiny (just tens of MBs)—you can grab it straight from the Ubuntu Software Center or run sudo apt install codeblocks for an instant setup.
• Its interface has a lot of similarities to VS, with intuitive project management, built-in compilers, and debugging tools. It’s extremely lightweight, making it great for quick projects or machines with limited resources.

3. Visual Studio Code (VS Code) + Targeted Extensions #

• While VS Code is technically a code editor, it transforms into a capable IDE with the right extensions—and it’s 100% native to Linux, with an initial install under 200MB.
  • For C#: Install the C# Dev Kit and C# extensions to get debugging, IntelliSense, project management, and even some of VS’s familiar workflow features.
  • For C++: Add the C/C++ extension, plus CMake Tools if you use CMake, and you’ll have full compile/debug support, code navigation, and syntax highlighting.
• The best part? You only install the plugins you need, so your total download size stays well under 5GB—often just a few hundred MBs for core functionality.

4. Eclipse CDT + C# Plugin #

• Eclipse is a long-standing native Linux IDE, and its CDT (C/C++ Development Tooling) component is a rock-solid choice for C++ development. The base Eclipse install is a few hundred MBs, and you can add C# support via the C# Development Tools plugin.
• It offers comprehensive features like debugging, code analysis, and version control integration. While the UI layout is a bit different from VS, it’s a fully-featured, free open-source option that doesn’t require huge downloads.

If you’re specifically craving a lighter, VS-adjacent experience, these are your best bets:

• Code::Blocks: As mentioned earlier, it’s the closest to VS in terms of workflow and UI among lightweight options—fast to launch, low resource usage, and perfect for smaller projects.
• Geany: An ultra-lightweight editor-IDE hybrid, with an install size of less than 10MB (just run sudo apt install geany). It supports both C# and C++, with basic compilation, debugging, and syntax highlighting. It’s not as full-featured as larger IDEs, but it’s blazingly fast and great for quick code edits or simple projects.
