Key features

The ReSharper extension offers a suite of productivity-enhancing features (debugging is coming soon):

Insightful code analysis helps you identify and fix code issues on the fly with real-time recommendations that improve readability and maintainability. ReSharper enforces consistent analysis rules for all members of your team, helping you maintain high code quality in any project.
The intuitive Solution Explorer gives you a central hub for managing all files, folders, NuGet packages, source generators, and projects in a solution – just like you would have in JetBrains Rider or Microsoft Visual Studio.
Advanced navigation and search make it easy to stay oriented and productive, even when you’re working on a complex solution or reviewing unfamiliar code. Jump instantly to types, symbols, files, or usages. You can even go directly to the external sources if a symbol is declared in the system or third-party dependencies of your project.
Reliable unit testing is provided by a powerful C# unit test runner that supports NUnit, xUnit.net, and MSTest. You can easily browse and select tests to run, review detailed output, and navigate directly to the source of failed tests from the results summary.
Comprehensive code refactorings , such as Rename, Extract Method, and Introduce Variable, help you safely restructure code and improve maintainability.
Smart coding assistance helps you write code faster. Reduce boilerplate and increase focus with intelligent completions that are fully aware of your project’s context, including live templates, auto-imports, and built-in documentation support.
Consistent code style keeps your code consistent with your team’s style guide. ReSharper automatically formats and indents your code as you type, ensuring clarity and uniformity without manual cleanup.

First steps

Install ReSharper from your preferred marketplace.
Open a workspace/folder in your VS Code-compatible editor.
ReSharper will automatically detect any .sln/.slnx/.slnf (solution) files or a csproj file in the folder:

If only one solution is found, it will open automatically.
If multiple solutions are found, click the Open Solution button in a popup menu to choose which one to open.

Compatibility recommendation

ReSharper for Visual Studio Code includes code completion, code analysis, and quick fixes that may overlap with Microsoft C# and C# Dev Kit extensions. To avoid confusion from overlapping features and to get the full ReSharper experience, we recommend disabling the Microsoft extensions while evaluating ReSharper. However, running all extensions simultaneously is valid – there’s no technical limitation preventing their concurrent use.

Telemetry and privacy

This extension collects telemetry data, which is used to help us understand how to improve the product. Please refer to JetBrains Privacy Notice for more information about data collection and use.
