What is Rider
Project Rider is a new C# IDE based on the IntelliJ platform and ReSharper.
Multiple runtime support
Project Rider supports the .NET Framework and Mono, with CoreCLR support in the works. It also includes templates for creating new projects, and when you create an empty project, it's literally empty!
Build, run and debug
Project Rider can build MSBuild and XBuild solutions as well as DNX/.NET CLI projects, and allows debugging .NET and Mono applications. DNX/.NET CLI debugging and CoreCLR support are coming.
Cross platform
As well as running and debugging multiple runtimes, Project Rider itself runs on multiple platforms. It runs on Windows and Mac OS X (Linux support is on the way).
Features
Code editing
A wide range of smart code editing features are implemented, from inserting braces and automatic formatting to Live Templates, quick info tooltips and gutter icons for inheritance navigation, context actions and so on.
Code inspections
Most of the inspections supported by ReSharper are displayed as errors, warnings, suggestions and hints in the editor. Project Rider also supports applying bulk actions to a whole file, and changing the severity of an inspection directly from the menu.
Navigation
Project Rider includes ReSharper's marquee "Go To Type" and "Go To File" navigation actions, and allows "Search Everywhere" to go to symbols, types, files and even search in settings and actions.
Refactorings
A limited set of refactorings is available at this early stage, but you can already rename symbols and introduce or inline variables.
Built-in decompiler
If you try to navigate to a type that you don't have the code to, Project Rider will decompile it for you, and display what the C# source would like look.
Debugger and more
Project Rider is coming with integrated debugger, stack trace explorer, NuGet browser and VCS support.
