Rider 2026.2.1 gives AI agents refactoring and debugging access; ReSharper defaults to out-of-process mode
↗
JetBrains' first minor update for the 2026.2 cycle lets Rider's AI agents call its refactoring engine and debugger directly, while ReSharper shifts to out-of-process mode by default.
The refactoring skill cuts median AI task time from 157.9s to 26.6s and cost from USD 0.52 to USD 0.19 by letting agents invoke Rider's refactoring engine instead of shelling out to git, sed, and dotnet build repeatedly. ReSharper's default move to out-of-process mode decouples its memory footprint from the IDE process, which has been a long-standing source of Visual Studio instability for .NET developers.

Rider's bundled refactoring-code skill reduces median task time by 83% and cost per task by 64% across fifteen C# refactoring tasks by letting AI agents call Rider's refactoring engine directly.
ReSharper 2026.2.1 runs in out-of-process mode by default, enabled by dotCover's new OOP support, with type and project dependency diagrams now functional in that mode.
A new debugging-code skill lets AI agents set breakpoints, inspect values, and step through code in C#, F#, C++, and mixed-language projects including Unity and Unreal Engine.
