What's new in Rider

WinForms designer

the long-awaited WinForms designer helps you create, observe, and modify the UI of your Windows Forms app.


WebStorm on Razor pages

Web-related languages on Razor pages have been moved to the WebStorm engine.


IIS Express support

for ASP.NET Core applications

Unit test coverage

and continuous testing for .NET Core comes to Linux and macOS


Initial C# 8.0 support

Thanks to ReSharper, Rider 2019.1 supports new language features.


Cross-platform performance profiling

for Mono and Mono Unity applications. .NET Core applications support will come with future updates.

Edit & Continue

helps you apply changes to the source code while the application is halted on a breakpoint. On resuming, the changes will be automatically applied to the code.


Rename for F#-defined symbols

now works across your entire solution


IL (Intermediate Language)

displays IL instructions for the class or method you currently have open in the editor and supports C#, VB.NET and F#.

Xamarin support

reaches new heights with Xcode integration and JetBrains Xamarin SDK


Breadcrumbs

now support C#, VB.NET, and F# files, helping you quickly understand where your cursor is with regard to the structure of the current document.


Unit Testing support

gets a performance boost and a smaller memory footprint

Features

Code analysis

Rider boasts 2,200+ live code inspections, with automated quick-fixes to resolve detected issues individually or in bulk. Solution-wide error analysis will monitor code issues and let you know if anything goes wrong, even in files that are not currently open.

Code editing

Rider's rich editor features different kinds of code completion and code templates, auto-inserting matching braces and import directives, quick info tooltips and gutter icons for inheritance navigation, context actions, and much more.

Refactorings

Most of ReSharper's 60+ refactorings are already available in Rider, and its 450+ context actions are all there. Rename, extract methods, interfaces and classes, move and copy types, use alternative syntax, and a lot more!

Unit test runner

Rider helps you run and debug unit tests based on NUnit, xUnit.net, or MSTest. You can explore tests, group them in different ways, break them down into individual sessions, see test output and navigate to source code from stack traces.

Debugger and more tools

Rider includes a debugger that works with .NET Framework, Mono and .NET Core applications, letting you step, watch, evaluate, and run to cursor. Other tools include a stack trace explorer, NuGet browser, and VCS and database support.

Databases and SQL

Work with SQL and databases without leaving Rider. Connect to databases, edit schemas and table data, run queries, and even analyze schemas with UML diagrams.

Navigation and search

Jump to any file, type, or member in your code base instantly, as well as quickly find settings and actions. Find usages of any symbol, or navigate from a symbol to the base and derived symbols, extension methods, or implementations.

Front-end technologies

Rider comes with JavaScript, TypeScript, HTML, CSS and Sass support built in. Take advantage of the refactorings, debugging, and unit testing capabilities included from WebStorm.

Extensibility

True to its roots, Rider supports a wide array of plugins developed for ReSharper and IntelliJ Platform. In addition to the bundled plugins (such as those for VCS, F#, and Unity support), plugins that support Markdown, .gitignore files, and Python scripts are available.

Rider for Unity

Rider comes backed up with Unity support.

Using Rider to write C# makes me happy. I have never seen code refactoring tools that actually work - always without exception. It's amazing when you can rely on it.

JetBrains Rider is the first tool I install after repaving my development machine.

I haven’t launched Visual Studio for months after I switched to JetBrains Rider.

Working with branches has never been so smooth since I started using Jetbrains’s Rider.

Dennis Doomen,
Continuous Improver at Aviva Solutions and author of Fluent Assertions

JetBrains Rider is my C# development tool of choice these days on both OS X and Windows. If you’re a longstanding ReSharper user, you’ll find it to be an almost seamless transition. I highly recommend the developer-friendly keystroke navigation and fine grained debugger support.

Jeremy Miller

In Rider, I just focus on working with my code, as it should be, instead of fighting my IDE. Rider gave me back the joy in writing .NET code.
