Rider

Rider supports .NET Framework, the new cross-platform .NET Core, and Mono based projects. This lets you develop a wide range of applications including .NET desktop applications, services and libraries, Unity games, Xamarin apps, ASP.NET, and ASP.NET Core web applications.

Rider provides 2200+ live code inspections, hundreds of context actions and refactorings brought by ReSharper, and combines them with the IntelliJ platform's solid IDE features. Despite a heavy feature set, Rider is designed to be fast and responsive.

As well as running and debugging multiple runtimes, Rider itself runs on multiple platforms: Windows, macOS, and Linux.
