Rider provides rich editing support and code insight for languages ​​used in .NET development, from C#, VB.NET, and F# to ASP.NET Razor syntax, JavaScript, TypeScript, XAML, XML, HTML, CSS, SCSS, JSON, and SQL.

What features are included under the free license?

With the new non-commercial license type, you can enjoy a full-featured IDE identical to the paid version. The only difference is in the Code With Me feature – you get the Code With Me Community with your free license.

Do RustRover and Aqua have the same terms for non-commercial use?

Yes, RustRover and Aqua follow the same guidelines for non-commercial use. They previously had slightly different criteria for certain use cases, but we’ve updated them to match the licensing model used for WebStorm and Rider.

Which license should I choose if I want to use Rider or WebStorm for both non-commercial and commercial projects?

If you intend to use Rider or WebStorm for commercial development for which you will receive direct or indirect commercial benefit or financial compensation as defined in the Toolbox Subscription Agreement for non-commercial use, you must purchase a commercial subscription (either individually or organizational). This license can then also be used for non-commercial development.

Functions

Language and project types

Rider allows you to open, edit, build, run, and debug most types of .NET applications, including desktop apps, web apps, libraries, and services (with the exception that debugging UWP applications is not yet supported). Applications that target Mono, such as Unity and Xamarin, are also supported, as well as the latest and greatest .NET Core applications.

Rider supports many languages ​​used in .NET development, including C#, F#, VB.NET, ASP.NET (both ASPX and Razor view engines), XAML, XML, JavaScript, TypeScript, JSON, HTML, CSS, SCSS, LESS , and SQL.

ReSharper + IntelliJ platform

Rider uses the UI and several features of the IntelliJ platform, which powers IntelliJ IDEA, WebStorm and other JetBrains IDEs. It is cross-platform, familiar to millions of developers, and provides core functionality such as VCS and database support.

On top of that, we’re adding ReSharper features: navigation and search, refactoring, code inspections, hotfixes, and so on. We’ve spent 10+ years building a feature set that helps you read, write, and navigate large .NET codebases, and all of this is now available to Rider users.

Designed to be smart and fast

Rider isn’t locked into a 32-bit process, which helps it gain deep insight into your code while remaining responsive. Rider opens (and reopens) most solutions with almost zero latency. External changes in solution? Switch Git branches? Not a problem: the rider catches up quickly.

When editing code, our top priority is to make sure you’re typing as fast as your fingers are trained, not just as fast as the IDE can process your input.

Works on Windows, macOS and Linux

Rider can be run on multiple platforms: Windows, macOS and various breeds of Linux. If you want to edit, build, run or debug Unity or .NET Core applications on a macOS, here is your full-featured IDE.

Intelligent code editor

Rider offers tons of smart code editing features, such as different types of code completion, auto-import of namespaces, auto-insertion of braces and matching delimiters, code reordering, live and postfix templates, controls and action hyperlinks in ASP.NET MVC, a multi-select mode, gutter icons for legacy navigation, as well as quick access to refactorings, generation, navigation and context actions.

Killer code analysis

Rider boasts 2200+ live code inspections to help you spot bugs and code smells. Over 1000 hotfixes are available to solve detected problems individually or in bulk: just press Alt+Enter to select one. For a bird’s-eye view of bugs in your projects, use solution-wide error analysis (SWEA): it will monitor bugs in your codebase and let you know if something goes wrong, even if you don’t have a problematic file open in your text editor.

Navigation and search

Jump to any file, type, or member in your codebase in no time, and find settings and actions, all with a standard Search Everywhere shortcut. You can find uses for all symbols, including cross-language use and use in string literals. For contextual navigation, use a single Navigate To shortcut that takes you from a symbol to its base and derived symbols, extension methods, or implementations.

Decompile

Want to know how third-party library code works? No problem with Rider: just use Go to Declaration on a library symbol and have Rider decompile the library type into C# in a regular editor tab. You can then navigate in decompiled code as you normally would in source code, and find and highlight usage areas. Sometimes, however, decompilation is not even necessary: ​​Rider can obtain source code from source servers such as the Microsoft Reference Source Center.

Refactoring

Most of ReSharper’s 60+ refactorings are already available in Rider, and its 450+ context actions are all there. You can rename, extract methods, interfaces and classes, move and copy types, use alternative syntax and much more! Check for available refactorings in the Refactor This popup, or use context actions accessed with AltEnter.

Unit testing

Rider lets you run and debug unit tests based on NUnit, xUnit.net, or MSTest in applications targeting the .NET Framework, .NET Core, and Mono. Rider marks test classes and methods with a gutter icon in the editor: click it or use the Alt+Enter menu to run, debug and manage tests. You can explore tests, group them in different ways, split them into individual sessions, view test results, and navigate to the source code from stack traces.

Troubleshooting

Rider includes a debugger that works with .NET Framework, Mono, and .NET Core applications. You can create multiple debug configurations, connect to external processes, set and manage breakpoints and breakpoint relationships, enter, over, and exit, run to cursor, set clocks, evaluate expressions, and explore threads.

Version control

Rider includes support for Git, Subversion, Mercurial, Perforce and TFS out of the box, with several version control systems supported via plugins. In the code editor, local changes are highlighted as you type. Using a dedicated VCS tool window, you can view local, incoming and repository changes, manage changelists, shelf changes for later use, view diff, commit and push. A built-in visual merge tool will help you resolve conflicts, and Rider will even let you know if a file you’re working on has changed since the last update.

Web development

With JetBrains Rider, you can develop modern web, mobile and desktop applications with built-in JavaScript, TypeScript, HTML, CSS and Sass support. Rider supports Node.js, React, Angular and Vue.js, integrates with package managers such as such as Bower, NPM and Yarn, and provides tight integration with various web development tools. Take advantage of code analysis, code completion, refactorings, debugging, and unit testing available in Rider for a full-stack web development experience.

Databases and SQL

You can work with SQL and databases without leaving Rider. Connect to databases, edit forms and tabular data, run queries and analyze forms with UML diagrams. Rider’s rich SQL editor comes with syntax highlighting, smart code completion, on-the-fly code analysis, code formatting and navigation.

Plugins

Rider leverages its roots by supporting a wide variety of plugins developed for the IntelliJ platform and ReSharper. In addition to bundled plugins (such as those for VCS, F#, and Unity support), you can choose to install additional plugins as you need them: when you open a file supported by a plugin you don’t use, Rider will suggest that you install it. For example, plugins are available that support Markdown, .gitignore files, and Python scripts.

What’s new

Rider 2024.2 introduces full-line code completion for more supported languages, reader mode with native rendering of documentation comments, a new Tasks tab and task dependency graphs for debugging, as well as improved navigation to class members. Game development updates include highlights such as Godot plugin bundling and improved Unreal Engine debugging. This release also introduces support for the .NET 9 Preview SDK, including initial support for C# 13 features. The updated feature set is enhanced with improvements to AI Assistant, such as improved code completion, AI-assisted VCS conflict resolution, and more.

SLNX support

Rider has finally introduced support for the Solution File Persistence Model, also known as the .slnx format for solution files, the latest clean and streamlined approach to storing all solution data. With Rider, you can now switch to the new format without any problems straight from the Solution Explorer. Just call up the solution node’s context menu, navigate to Save As… and select Save as XML Solution (.slnx). You will then have the option to open your solution via the newly created .slnx file to make the transition to the new format seamless.

Full line code completion for C#, C++, JS/TS, CSS

Rider 2024.2 introduces support for a new type of code completion: single-line gray text that completes statements based on the context of the current file. These proposals are powered by language models that run locally without sending any code over the internet.
