透過對新式 C# 14 擴展的支援進行開發

ReSharper is a productivity and code quality plugin for Visual Studio, developed by JetBrains. It helps .NET developers write cleaner, more efficient code. By analyzing code on-the-fly, ReSharper identifies potential errors and suggests fixes. It also automates code refactoring, allowing developers to safely restructure their codebase. These features improve developer productivity and maintainability of the code, making ReSharper a valuable tool for both individual developers and development teams.

The ReSharper 2025.3 update improves support for C# 14 extension members by enabling developers to work with the new syntax more accurately and efficiently across the entire toolset. Refactorings such as Change Signature, Convert Method to Property, Make Static, and Safe Delete now function reliably with extension methods, properties, and operators, while navigation, value tracking, and usage analysis correctly interpret these new member types. The update also enhances import completion and optimize-using operations to recognize extension members in more contexts, and adds inspections and quick-fixes that help developers transition smoothly between classic and modern extension patterns.
