Rider 2026.2 EAP 3: Cost-effective Agentic Test Coverage, Code Change Previews, GameDev Templates, and NuGet Improvements

JetBrains Rider 2026.2 EAP 3 introduces several notable features: an AI agent skill for unit test generation that leverages dotCover coverage data to reduce token consumption by up to 50%; intention previews showing diff-based code change previews before applying quick-fixes; a new Game Development section in the New Project dialog with Godot templates (including C++ GDExtension and CMake support); a redesigned NuGet tool window that separates browsing from dependency management and highlights available updates; and backend garbage collection optimizations reducing memory usage by 7–8%.
