Novidades no Rider 2025.1

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. Saiba mais.

A partir do Rider 2025.1, o desenvolvimento remoto em hosts Windows agora é suportado através do JetBrains Toolbox App. Embora o Gateway continue disponível para conexões Linux, a transição completa para o Toolbox App como o principal hub para desenvolvimento remoto está em andamento. Saiba mais sobre como você pode usar o JetBrains Toolbox App para se conectar a máquinas host Windows, macOS e Linux neste post do blog.

O Rider agora se integra ao Unity Profiler, trazendo insights de desempenho da CPU diretamente para o seu editor. O IDE busca snapshots de uso da CPU e mostra inline no seu código, facilitando a identificação de pontos críticos de desempenho enquanto você escreve e depura seus scripts Unity. Você pode navegar perfeitamente de chamadas na visualização hierárquica do Unity Profiler para seus métodos correspondentes no Rider.

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.

Anteriormente, o uso de nameof exigia a especificação de todos os argumentos de tipo, causando uma verbosidade desnecessária. O C# 14 permite nameof(List<>) sem listar explicitamente os argumentos de tipo. Rider now detects redundant generic type arguments in nameof expressions and provides a quick- fix to simplify them.

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.

Para os usuários de Windows e Linux, agora o IDE oferece uma nova opção para fundir o menu principal com a barra de ferramentas principal, criando uma interface mais enxuta.

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.

Os auxiliares de marcação Razor e o suporte a componentes Blazor foram completamente reconstruídos para o 2025.1. Essa reformulação há muito necessária traz uma redução de 5%–10% no tempo de análise para grandes soluções ASP.NET com uso intensivo de componentes. 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 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.

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.

Agora você pode ver os detalhes do commit diretamente na visualização de diferenças. 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.

Agora, você pode iniciar qualquer ferramenta para realizar uma verificação pré-commit juntamente com inspeções e formatação. Vverificações personalizadas podem ser definidas como configurações de execução na caixa de diálogo Run Configuration. Isso ajuda a detectar possíveis problemas antecipadamente e garante que o código atenda aos padrões do projeto antes de passar por commit.

We've added support for the NoesisGUI framework for both Unreal Engine and Unity projects.

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 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 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.
