Questions tagged [rider]

Rider is a cross-platform (Windows, Linux & macOS) IDE created by JetBrains for the .NET/Mono family of languages such as C#. Use this tag if your questions are specific to using Rider or are specific to Rider's behavior. Rider troubleshooting and bugs are off-topic.

Rider provides 2,000+ live code inspections, 500+ refactorings, multiple code navigation helpers, a unit test runner, an integrated debugger, rich coding assistance, and dozens of other features that help you read, write, and navigate large .NET codebases. Most of these features are also found in ReSharper, a popular Visual Studio plugin by JetBrains.

Rider supports most of the languages used in .NET development, from C#, VB.NET, and F# to ASP.NET Razor syntax, JavaScript, TypeScript, XAML, HTML, CSS, SCSS, JSON, and SQL.
