ReSharper has been available in Visual Studio for 21 years and is now released for VS Code and compatible editors including Cursor and WinSurf. The extension is available through the VS Code extensions marketplace and the open VSX registry. It is included with .NET Ultimate subscriptions and is free for non-commercial use, matching Rider's licensing model. This enables students, hobbyists, open source contributors, and content creators to access the tool.
ReSharper provides a solution explorer supporting SLN, SLNX, and SLNF files with solution folders. The tree view displays error and warning counts for projects and files. Users can create new files using templates for classes, interfaces, and structs. The explorer shows NuGet packages, project references, and source generators. Package management includes installation, version selection, and updates directly from the interface.
An outline view displays types and methods for navigation within files, supporting both C# and Razor files. Project build operations use ReSharper Build, which optimizes compilation by only rebuilding projects when API changes occur. The system performs faster up-to-date checks than MSBuild by leveraging IDE knowledge of file changes. Test integration allows running unit tests with pass/fail indicators and error display.
