Rider 2026.2 EAP 5: Code Quality Checks for Your AI Agents, and More. | The .NET Tools Blog

Rider 2026.2 EAP 5 introduces several enhancements aimed at improving AI-assisted development, including a new non-modal Welcome screen for a faster startup and bundled quality-check hooks for AI agents like Claude Code and Codex. These hooks, specifically PostToolUse, ensure that agent-generated code undergoes IDE-level validation to detect issues and formatting inconsistencies before proceeding, thus raising the quality bar set by the IDE itself rather than the AI agent. Additionally, the update makes the "Explain with AI" feature more accessible, allowing .NET developers to receive clearer explanations of build errors and runtime exceptions directly from the IDE, transforming complex diagnostics into understandable insights for quicker resolution. This development cycle encourages users to explore and give feedback on how these new features enhance their projects.
