Mastering Global Exception Handling & ProblemDetails in ASP.NET Core WebAPI

Are your Web API controllers cluttered with repetitive try-catch blocks? In this tutorial, we dive deep into building a centralized, production-grade Global Exception Handling mechanism in ASP.NET Core Web API (.NET 10). We will walk through the modern IExceptionHandler interface, replace legacy custom middleware, and implement the industry-standard RFC 7807 ProblemDetails format to ensure your API returns clean, secure, and predictable custom error responses.
