ReSharper 2026.1 最新变化

Marking a new step in the evolution of performance monitoring, ReSharper 2026.1 introduces the Monitoring tool window. 这个全新的专用工具窗口能提供更清晰、更全面的运行时性能概览，并自动检测问题，帮助您发现优化机会。

The Monitoring tool window lets you observe key runtime metrics of your application as it runs or during debugging. It builds on the capabilities already previously available through our .NET profiling tools and Dynamic Program Analysis (DPA), but brings them together in a single view that makes it easier to evaluate runtime behavior at a glance.

ReSharper 现已支持 Visual Studio Code 以及 Cursor 和 Google Antigravity 等兼容编辑器，将 JetBrains 的 C# 工具引入您选择的编辑器中。

The extension provides real-time code analysis, refactorings, and navigation for C#, XAML, Razor, and Blazor. 它还包含一个用于管理项目和源代码生成器的 Solution Explorer，并支持对 NUnit、xUnit.net 和 MSTest 进行内置单元测试。

ReSharper 2026.1 expands its support for C# extension members, helping you work more efficiently with the evolving language features.

A new Consolidate extension members context action merges compatible extension declarations and classic extension methods into a single block. The Import extension member quick-fix has also been improved and now supports all kinds of extension members, automatically adding missing using directives when needed.

ReSharper 2026.1 introduces early support for upcoming C# language updates, helping you experiment with new syntax as the language evolves.

This release includes initial support for collection expression arguments and support for the [ExtendedLayout] attribute, ensuring ReSharper continues to work smoothly with the latest compiler innovations.

This release adds several new inspections and style options to help you write safer and more consistent code.

ReSharper now detects short-lived HttpClient instances and suggests safer reuse patterns. It also warns you when ImmutableArray<T> is used with collection initializers, which can lead to a runtime NullReferenceException.

其他改进包括：

• A new inspection for enforcing the order of accessor methods in properties and events.
• A syntax style option for empty strings, allowing you to choose between string.Empty and "".
• Improved nullable reference type migration, with an option to insert #nullable enable automatically in new files.
• Enhanced code completion that can generate method definitions based on [LoggerMessage] attributes.

ReSharper 2026.1 improvements to C++ support include:

• Performance: Faster startup times and lower memory usage in Unreal Engine projects.
• Language support: Support for the C23/C++26 #embed directive, C++23 extended floating-point types, the C2Y _Countof operator, and other features.
• Coding assistance: Auto-import for C++20 modules and postfix completion for primitive types, literals, and user-defined literal suffixes.
• Code analysis: New inspections for out-of-order designated initializers and override visibility mismatches, update of bundled Clang-Tidy to LLVM 22.
• Unreal Engine: Richer Blueprint integration in Code Vision and Find Usages, compatibility fixes for the upcoming Unreal Engine 5.8.

ReSharper 中的多个编辑器 UI 元素已更新，以更好地与 Visual Studio 的现代外观保持一致。

重新设计后，代码补全 UI 现在可以在编辑器内呈现更简洁且更一致的外观。

我们还对部分相关的 UI 组件进行了现代化升级，包括参数信息弹出窗口、工具提示和其他编辑器弹出窗口，以替换过时的视觉效果，并改进它们在不同主题和 DPI 设置下的外观。
