Agents can write a lot of your .NET code now. You still decide what ships. In this 15-minute live demo, we hand a real task to a coding agent inside Rider with JetBrains Air, then check the result with Rider’s tests, navigation, and debugger, and send review notes back to the agent for another pass. Then we give an agent the dotTrace profiling skill so it can find a real bottleneck from profiling data instead of guessing. Not using Rider? We’ll finish with how ReSharper brings the same .NET code intelligence to Visual Studio and VS Code.
