What is Exception Handling in ASP.NET Core?

Exception handling in ASP.NET Core is the process of detecting, managing, logging, and responding to unexpected errors that occur during application execution. Proper exception handling prevents applications from exposing sensitive technical information and allows APIs to return consistent and meaningful responses to clients. ASP.NET Core provides middleware-based approaches for centralized exception handling. Developers can also use structured logging and standardized error responses such as Problem Details to provide clients with appropriate HTTP status codes and error information. A well-designed exception-handling strategy should distinguish between expected business errors and unexpected system failures.
