In this video, I’ll walk you through two clean, production-ready ways to catch and handle unhandled exceptions in your .NET apps: a custom middleware approach and the new IExceptionHandler feature introduced in .NET 8. You’ll see how to prevent leaking stack traces and internal exception details to your clients, return structured ProblemDetails responses, log exceptions cleanly, and even chain multiple handlers to deal with different exception types like FluentValidation’s ValidationException. I also show how to use ProblemDetailsService for even cleaner error output — including how to add global metadata like requestId to every error response. Whether you’re starting from scratch or upgrading your error handling setup, this video will help you ship more secure, maintainable APIs. No fluff — just practical .NET guidance that you can apply immediately.
