Integrated .NET Tooling for AI Editors
JetBrains has updated its ReSharper extension (version 2026.2), adding native .NET debugging, unit test execution, and solution navigation to AI-first editors like Cursor, Google Antigravity IDE, Devin Desktop, and Kiro. Previously, .NET engineers using agentic code editors were forced into a two-window workflow—editing with AI in Cursor while keeping Visual Studio or Rider open alongside for debugging and test runner capabilities.
Validating AI-Generated C# Boilerplate
Generative models excel at producing initial C# code, but frequently introduce subtle runtime bugs, performance bottlenecks, or architectural mismatches. The ReSharper extension runs deep static analysis directly over AI-generated code snippets inside the editor. This allows developers to catch style violations and structural errors before executing or committing the code.
Installation and Availability
The extension is available on the Open VSX Registry for Cursor, Antigravity IDE, Devin Desktop, and Kiro, as well as on the Visual Studio Code Marketplace for standard VS Code installs. Installing the extension automatically initiates a free 30-day trial with zero manual configuration needed.
