.NET 9 Global Exception Handler: The RIGHT Way with IExceptionHandler (No Middleware!)
In this tutorial, we dive deep into the modern, clean approach for centralized exception handling in ASP.NET Core and .NET 9: the IExceptionHandler interface.
🔥Why IExceptionHandler is a Game Changer in .NET 9:
Forget writing bulky, complex middleware for error handling! The IExceptionHandler service provides a simple, dependency-injected way to catch all unhandled exceptions globally and generate clean, standardized responses.
*What You'll Learn & Implement:*
✅The Problem: Why traditional try/catch blocks and generic middleware are inefficient.
✅ The Solution: How to create a custom IExceptionHandler implementation.
✅ Configuration: Registering your handler in the .NET 9 Minimal API/Program.cs.
✅ Clean Responses: Converting unhandled exceptions into proper HTTP status codes (e.g., 500, 400, 404) and JSON Problem Details.
✅ Logging: Ensuring all critical errors are logged effectively before the response is sent.
