Rider 2025.1 最新变化

Navigate your entire codebase with Rider's new Files view. This redesigned view lives alongside your Solution view. Files（文件）视图从根显示完整仓库结构，让您可以轻松处理全栈项目、配置文件以及构成现代开发环境的其他所有内容。 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. 了解详情。

Starting with Rider 2025.1, remote development on Windows hosts is now supported via the JetBrains Toolbox App. 虽然 Gateway 可用于 Linux 连接，但全面过渡到 Toolbox App 作为远程开发的主要中心正在进行中。 请参阅这篇博文，了解如何使用 JetBrains Toolbox App 连接到 Windows、macOS 和 Linux 主机。

Rider now integrates with the Unity Profiler, bringing CPU performance insights directly into your editor. The IDE fetches CPU usage snapshots and displays them inline with your code, making it easy to spot performance hotspots as you write and debug your Unity scripts. 您可以从 Unity Profiler 层次结构视图中的调用无缝导航到 Rider 中的相应方法。

针对游戏开发的更多更新

• 对来自新 SDK 的项目模板的支持。
• 创建、运行和调试以新 SDK 为目标的项目。
• 对 C# 14 和 VB 17.13 最新预览功能的初步支持。

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.

Previously, using nameof required specifying all type arguments, causing unnecessary verbosity. C# 14 allows nameof(List<>) without explicitly listing type arguments. 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.

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.

对于 Windows 和 Linux 用户，IDE 现在提供了一个将主菜单与主工具栏合并的新选项，有助于创建更精简的界面。

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.

Razor tag helpers and Blazor component support have been completely rebuilt for 2025.1. This long-needed overhaul brings a 5%–10% reduction in analysis time for large ASP.NET solutions with heavy component usage. 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.

您现在可以直接在差异视图中查看提交详细信息。 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.

现在，您可以启动任意工具来执行提交前检查以及检查和格式设置。 自定义检查可以在 Run Configuration（运行配置）对话框中配置为运行配置。 这有助于您尽早发现潜在问题并确保代码在提交之前符合项目标准。

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.

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.
