Rider 2026.2: IDE Intelligence for AI Agents and Performance Boost
Update opens IDE intelligence to AI agents and enhances performance.
1IDE Intelligence for AI Coding Agents
Rider 2026.2 directly integrates AI coding agents with the IDE's intelligence. Agents can now use IDE data instead of reconstructing project information from files and terminal output. New skills include testing, profiling, refactoring, and .NET workflows.
2GitHub Copilot Integration
Thanks to a partnership between JetBrains and Microsoft, GitHub Copilot is now natively integrated into Rider. You can use Copilot in AI chat with OAuth sign-in. Additionally, third-party completion models can be connected.
3Performance Improvements
Rider 2026.2 delivers significant performance boosts for .NET and Unreal Engine projects. Debugger launch is 2.8 seconds faster on Windows, branch switching is 2-3x faster, and memory usage is reduced by 7-8%. C++ indexing for Unreal Engine is twice as fast.
4WPF Hot Reload
This release introduces WPF Hot Reload, allowing you to edit XAML files while the app runs. Changes are applied instantly without restarting. You can tweak layouts, styles, templates, and resources seamlessly.
5Game Development Updates
Key updates include faster Unreal Engine indexing, game-aware AI agent skills, and Natvis support on Linux/macOS. Godot developers benefit from a new GDScript formatter and drag-and-drop scene node features.
6Language Support and Other Features
The update brings the latest ReSharper improvements for C#, C++26 reflection support, and F# debugging fixes. Other highlights include file-based C# templates, TypeScript 7 support, and built-in Azure Functions integration.
