ReSharper 2025.1最新变化

Previously, using nameof required specifying all type arguments, causing unnecessary verbosity. C# 14 允许 nameof(List<>) 而不显式列出类型实参。 ReSharper 现在可以检测 nameof 表达式中的冗余泛型类型实参，并提供了快速修复来简化它们。

C# 14 在 ReadOnlySpan<T>、Span<T> 和 T[] 之间引入了新隐式转换，使基于 span 的代码更加直观。 ReSharper 现在完全支持这些转换规则，帮助您编写高效、现代的 C# 代码。

在 C# 14 中，您现在可以在 lambda 表达式中使用 ref、out、in 和 scoped 等形参修饰符，而无需显式形参类型。 ReSharper 提供了快速修复来移除冗余的类型规范。

A new context action lets you convert string interpolation back to concatenation. While ReSharper has long supported converting string concatenation ("Id = " + someId) to interpolation ($"Id = {someId}") or string.Format("Id = {0}", someId), this update completes the cycle by allowing the reverse transformation, giving you more flexibility in structuring string expressions.

ReSharper now detects and highlights even more code duplication patterns appearing in conditional constructs like if and switch, and makes refactoring suggestions for cleaner, more maintainable code.

ReSharper now detects cases where a method-level CancellationToken is mistakenly used instead of a local token. It offers a quick-fix to replace the incorrect token or merge multiple tokens using CancellationTokenSource.CreateLinkedTokenSource().

Calling .ToString() on enum members can incur unnecessary runtime overhead. ReSharper now suggests replacing it with nameof(SomeEnum.Member), improving performance and clarity.

ReSharper 2025.1 suggests explicit tuple component names instead of generic ItemN names, making your code more readable and self-documenting.

ReSharper now warns you when Stream.Read() and ReadAsync() methods are used without checking their return values, which can lead to incomplete data reads. It suggests replacing them with .ReadExactly() to ensure correctness.

Since Debug.Assert calls are removed in RELEASE builds, ReSharper warns you about assertions that modify state and could lead to unexpected behavior in production code.

ReSharper 2025.1 为 C++ 支持带来了多项改进：

• 引入了 Inline Macro（内联宏）重构。
• 支持多个新的 GNU 语言扩展。
• 包含大量蓝图资源的 Unreal Engine 项目的内存使用优化。
• 捆绑了 Clang-Tidy 20，并支持在 ARM 设备上使用 Clang-Tidy。
• 更新了 GoogleTest 支持。

A new formatting action applies chop formatting to various C# constructs, improving code readability and consistency.

We've refined Push-to-Hint behavior in ReSharper to prevent unintended activations caused by conflicts with other Ctrl-based shortcuts. Additionally, we've introduced a visual indicator to show when the mode is active.

ReSharper now visually highlights members that extend base classes or implement specific interfaces when you place the caret over a type name in the base types clause.

We've been testing the latest out-of-process (OOP) implementation of ReSharper internally for the past four weeks, and we're truly excited about the results so far. While we're still working to support all features and fix known issues, the core functionality that makes ReSharper an essential part of your development workflow is coming together nicely.

dotMemory 现在已完全集成到 Microsoft Visual Studio 中。 以前，您在 Visual Studio 中只能触发性能分析，必须切换到独立的 dotMemory 应用程序才能分析结果。 现在，您可以在 IDE 中完成应用程序的性能分析和内存快照分析。

Qodana is a team code quality tool that leverages JetBrains inspections to help teams run checks and audits and establish quality gates in their favorite CI/CD pipeline. Now, you can download the Qodana Code quality extension via your ReSharper installer to bring Qodana Cloud or self-hosted Qodana projects into Visual Studio.

Identify code issues, bugs, and vulnerabilities, run the analyses directly in your pipeline, and then view issues in your IDE where you work for better contextual updates and learning. You also have the option to download it as a standalone tool using the ReSharper installer.

ReSharper 2025.1 附带了一个捆绑的 Unity 插件，支持所有主要的游戏开发工作流。 该插件提供了针对 Unity 事件函数和 API 的代码补全、带有 Unity 文档链接的工具提示摘要，以及检测常见问题的专用检查。 它包括对 ShaderLab 文件的支持，提供语法高亮、代码补全和错误检测。 该插件还会自动处理 .meta 文件，并检测 Unity 场景、预制件和资源中字段和方法的隐式使用。

ReSharper C++ continues to provide dedicated support for Unreal Engine development.
