GitHub Copilot for Visual Studio

GitHub Copilot integrates into Visual Studio and uses nearby code, comments, and open-file context to generate suggestions. It can propose a line, a larger code block, or an entire function while you work in the editor.

Yes, a developer can ask Copilot to draft tests based on an existing method, class, or comment. The generated test still needs to be reviewed and run because the model does not prove that the assertions cover the intended behavior.

This product is for Visual Studio, Microsoft's full Windows development environment, rather than only Visual Studio Code. It is commonly used with Visual Studio 2022 projects, where suggestions appear directly in the coding workflow.

IntelliCode focuses on Microsoft-assisted completions, while ReSharper adds JetBrains code analysis, refactoring, and navigation features. Copilot's distinctive role is generating context-aware natural-language-to-code suggestions and larger implementation drafts.
