Rider 2025.1 delivers initial support for .NET 10 and C# 14 preview features. This release introduces the new Files view for repository-wide visibility, a Roslyn syntax tree visualizer, and numerous enhancements for debugging both .NET and C++ solutions. Game developers can leverage the Unity Profiler integration, while AI power users benefit from a fresh selection of newly supported LLMs.
JetBrains AI Assistant был существенно обновлен, и теперь разработка с использованием функций на базе ИИ стала доступнее и эффективнее. With this release, AI features are now free in JetBrains IDEs, including unlimited code completion, support for local models, and credit-based access to cloud-based features. A new subscription system makes it easy to scale up with AI Pro and AI Ultimate tiers.
This release introduces major enhancements to boost productivity and reduce repetitive work, including smarter code completion, support for new cloud models like GPT-4.1 (сoming soon), Claude 3.7, and Gemini 2.0, advanced RAG-based context awareness, and a new Edit mode for multi-file edits directly from chat.
Navigate your entire codebase with Rider's new Files view. This redesigned view lives alongside your Solution view. The Files view shows your complete repository structure from the root, making it easier to work with full-stack projects, configuration files, and everything else that makes up your modern development environment. To enable repository-wide visibility, select New Files View in the Solution Explorer tool window settings.
You can now view and explore C# syntax trees directly inside the IDE with Rider's new Roslyn syntax tree visualizer. The visualizer provides real-time tree visualization that stays synchronized with your editor.
You can interactively explore nodes and inspect their properties, quickly navigate between code and corresponding tree nodes, and use comprehensive search and filtering capabilities. Подробнее.
В Rider 2025.1 появилась поддержка удаленной разработки на Windows-хостах через JetBrains Toolbox App. Для Linux пока остается Gateway, но со временем основным инструментом для удаленной работы станет именно Toolbox App. Подробнее о подключении к хост-машинам Windows, macOS и Linux с помощью JetBrains Toolbox App читайте в нашем блоге.
Rider теперь интегрируется с Unity Profiler и показывает информацию о загрузке процессора прямо в редакторе. IDE получает снэпшоты использования процессора и отображает их рядом с кодом, помогая находить проблемные места при написании и отладке скриптов Unity. Можно быстро переходить от вызовов в Unity Profiler к соответствующим методам в Rider.
В этой версии вас ждет несколько новых инспекций, выявляющих распространенные ошибки и неэффективные конструкции во всех версиях C#. Среди них:
For information on these and other improvements to code analysis, please see What's New in ReSharper 2025.1.
Rider 2025.1 introduces scoped quick-fixes for Roslyn analyzers, allowing you to apply fixes at the file, project, or solution level in a single action. Now, instead of repeatedly applying the same fix, you can select the scope – whether a single file, an entire project, or the full solution – directly from the quick-fix menu.
Rider 2025.1 brings initial support for .NET 10 and C# 14 preview features, helping you stay ahead of the curve with the latest language enhancements.
nameof
для непривязанных обобщенных типов Раньше при использовании nameof
требовалось указывать все аргументы типа, что делало код излишне громоздким. В C# 14 можно использовать nameof(List<>)
без явного указания аргументов типа. Rider now detects redundant generic type arguments in nameof
expressions and provides a quick- fix to simplify them.
Span<T>
C# 14 introduces new implicit conversions between ReadOnlySpan<T>
, Span<T>
, and T[]
, making span-based code more intuitive. Rider now fully supports these conversion rules, helping you write efficient, modern C# code.
C# 14 позволяет использовать модификаторы параметров, такие как ref
, out
, in
и scoped
, в лямбда-выражениях без явного указания типов параметров. Rider offers a quick- fix to remove redundant type specifications.

Inferred types are now shown for more patterns, improving clarity when working with match expressions and other pattern-using constructs.
We've rewritten various parts of F# code completion, so it now works faster, uses less memory, and provides more accurate suggestions.
We've optimized building metadata, fixed issues leading to inconsistent analysis and freezes, and improved cancellation for better code editing performance.
Подробнее об устраненных ошибках и улучшениях поддержки F# читайте здесь.
На Windows и Linux теперь можно объединить главное меню с панелью инструментов — интерфейс станет чище и удобнее.
You can set Rider to automatically update plugins in the background. It will download all available and compatible updates and apply them the next time the IDE is restarted without additional notifications.
For this release, we've completely overhauled our string interning system. IDEs process an enormous number of strings, including source code, syntax elements, symbol names, and file paths, so efficient string handling is critical. Our new string interning system stores, on average, four times as many unique strings as its previous iteration and consumes about half as much memory to do so, freeing up resources in large-scale .NET projects.
Для версии 2025.1 была полностью переработана поддержка Razor tag helpers и компонентов Blazor. Эта давно необходимая переработка сокращает время анализа на 5–10% для больших решений ASP.NET с интенсивным использованием компонентов. You'll also experience fewer reanalysis events when editing .cshtml/.razor
files, as well as significantly reduced false error reporting.
For the 2025.1 release we have focused on improving AI-based completion in the context of web framework components. These changes affect local full line code completion as well as cloud-based completion suggestions.
Rider now ensures that AI-generated unit tests follow existing naming conventions in your project. This improvement helps maintain consistency across your test suite, reducing the need for manual renaming and making test integration smoother and more intuitive.

Rider now offers automatic attachment to child and grandchild processes during .NET application debugging. When enabled in the run/debug configurations, the IDE tracks and attaches to all .NET processes spawned within the application's process tree.
Enable this feature using the new Attach to child .NET processes checkbox.
Rider 2025.1 comes with improved data visualization for LINQ expressions, making it easier for you to understand and debug complex LINQ queries directly in the debugger. You'll now be able to inspect query execution, see intermediate results, and better understand how your LINQ operations transform the data. For more information, please see documentation for this feature.
Rider 2025.1 introduces new breakpoint setup options that allow you to configure exception breakpoints with greater precision. Now, you can:
Rider 2025.1 comes with lots of updates for C++ debugging, which might be particularly useful for Unreal Engine development. Click here to see what's new.
dotnet watch
as a run/debug configuration Rider 2025.1 introduces a dedicated run and debug configuration for dotnet watch
, streamlining the development workflow for projects that need automatic rebuilding and restarting as code changes.
This enhancement particularly benefits ASP.NET Core and .NET developers, as it continuously builds your application when you modify .cs
, .html
, or .css
files. The feature also extends to test files, enabling automatic test execution whenever your code changes.
Input and output redirection for run configurations is available in Rider 2025.1. You can now easily specify a file to be used as standard input (stdin
) and direct program output to a file, streamlining debugging and testing workflows.
Additionally, you can now attach log files to a run configuration. These files will then be shown in separate tabs in the Run or Debug tool windows during program execution.
.env
files Rider 2025.1 simplifies the management of environment variables. Instead of manually entering variables, you can now use .env
files directly in your run/debug configurations. Look for the folder icon (Browse) next to the Environment Variables field to attach your .env
files. Rider will load them on the next launch. You can even use multiple files across different projects to maintain consistent configurations.
Теперь сведения о коммите можно посмотреть прямо на панели Diff. The diff dialog now displays the commit message, author, date and time, and full commit hash, giving you a clearer view of a file's history and helping you understand modifications faster.
Теперь вы можете запустить любой инструмент для выполнения дополнительных проверок перед коммитом, помимо инспекций и форматирования. Пользовательские проверки можно настроить в диалоге Run Configuration как конфигурации запуска. This helps you catch potential issues early and ensures your code meets project standards before it's committed.
Rider now automatically fetches changes when you add or update a Git remote, ensuring you always have the latest branch list and commit history without needing to fetch them manually. Newly fetched branches will immediately appear in the Git branch tree. You'll be able to start working with them right away, and your repository will always be up to date.
For more information on VCS updates, please see this page.
We've added support for the NoesisGUI framework for both Unreal Engine and Unity projects.
Rider будет использовать языковой сервер NoesisGUI для автодополнения элементов XAML и выражений привязки, а также для подсветки ошибок и отображения их описаний. Кроме того, Rider теперь показывает превью интерфейса, описанного в XAML-файле.
While our main focus for this release was on the debugger, we still had time to work on several Unreal Engine-related updates and fixes, such as for the issue causing Rider not to run unit tests created from the ComplexTest
template. Rider теперь распознает и подсвечивает макросы рефлексии UMETA
и UPARAM
, предоставляя автодополнение и документацию во всплывающих подсказках как для самих макросов, так и для их атрибутов.
We've also been working on optimizations for Blueprint indexing. We've reduced memory usage and made more parts of the process run asynchronously on a background thread. This should result in a more responsive experience while Rider indexes your Blueprints the first time a solution opens.
We've implemented many useful updates for the native debugger in this release, including significant performance improvements that make stepping in very large projects up to 50 times faster! You can find more details in this blog post.
Rider's support for Natvis files has been improved. Now, Natvis files are automatically loaded from the AppData
folder, and there is a new option to specify custom locations containing more files.
Rider will now recognize synthetic items in Natvis files, which means the debugger will show additional nodes when displaying the contents of a type.
The debugger can now automatically attach to child processes, and custom rules can be applied to specify which child processes it should attach to or ignore.
The Detach process action now works with native applications.
You can use module.dll!expr
syntax to specify the context operator for an expression, telling the debugger where to look to resolve a symbol in a variable or breakpoint.
Unreal Engine projects also benefit from updates to the ReSharper C++ engine, including the new Inline Macro refactoring and the implementation of a popular request from users to allow the use of different syntax highlighting for various keywords. See the What's New in ReSharper C++ page for more details.
We've added an experimental integration with Unity's profiler. Once you've enabled it in the settings, clicking an entry in the profiler's Hierarchy view will open the file in Rider and show profile information for each line.
Learn more about this feature from Rider's documentation.
The IDE now correctly recognizes the version control bindings for packages added as external folders. This means you can commit to both your main project and any external package folders that you're working with.
Rider's color highlighting now supports the additional named colors added in Unity 6.
Rider's remote development support now works better with Unity projects. Specifically, the shader variants selector is now available, and the Unity Explorer view will now correctly select the open file.
We've made some fixes to the Rider package bundled with Unity. For example, root namespaces are no longer occasionally missing, the Unity editor log file can be opened directly from the Unity settings page, and Rider entries are no longer duplicated on Linux.
Rider's support for Godot now supports .uid
files, which were introduced in Godot 4.4. When files are moved with Rider or renamed with a refactoring, the corresponding .uid
files are moved together to maintain project integrity.
Hot Reload now works for Godot C# projects, meaning that changes to C# code can be compiled and applied while the program is suspended at a breakpoint during debugging.
This release eliminates an unnecessary warning about a missing default constructor on abstract classes. We've also contributed a couple of pull requests to Godot to improve integration with Rider, such as one for automatically configuring an external editor's command line arguments when the selected editor is changed.
Rider 2025.1 now supports running and debugging Azure Function projects via the .NET Aspire and the Azure Toolkit for Rider plugins. Please share any feedback you might have on the functionality in the comments on this ticket.
The .NET Aspire plugin now also supports running and debugging AWS Lambda Function projects in Rider. For more information, please see this GitHub issue.
Rider 2025.1 now supports remote debugging of Azure App Services projects via the Azure Toolkit for Rider plugin (Azure Functions and Azure Web Apps are supported).
Rider 2025.1 comes with a host of improvements for Angular, namely:
Rider 2025.1 introduces proper support for Blazor WebAssembly (WASM) publishing. You can now use the .NET Publish | Publish to Folder configuration, which will use browser-wasm
target runtime without encountering missing files in the output.
Rider now prioritizes service-powered quick fixes, especially for imports, when internal suggestions are unavailable. This ensures that relevant fixes appear first, reducing friction in resolving issues and improving the overall coding experience.

Previously, to start a Code With Me session in Rider, you had to manually enable it using the Enable Code With Me action and performing a restart. In Rider 2025.1, this step is no longer necessary — you can start a collaborative session right away without restarting the IDE.
The 2025.1 release introduces the reworked terminal architecture, which is available in Beta. The terminal now runs on a stable, standards-compliant core and uses the IDE's editor to render the UI. Эти изменения позволили нам добавить новые функции, одновременно обеспечив совместимость и производительность на разных локальных и удаленных платформах. Подробнее о планах и ходе работы читайте в нашем блоге.
