ReSharper 2026.1 Early Access Program Has Begun | The .NET Tools Blog

The ReSharper 2026.1 Early Access Program (EAP) introduces a range of new features and improvements aimed at enhancing productivity and code quality for developers. Key updates include smarter code generation and completion for C#, with features like the ability to generate partial member definitions and improved logging workflows. Additionally, new inspections have been added to enhance runtime safety, such as detecting problematic ImmutableArray initializations and inefficient HttpClient usage. Performance optimizations have been made to reduce runtime overhead, and C++ language support has been expanded to include initial support for C++23 floating-point types, among other improvements. The update also enhances project model handling, particularly for WinUI 3 projects, and integrates Dynamic Program Analysis into a broader performance monitoring framework. Users are encouraged to explore these updates and provide feedback to refine the features before the final release.
