error-handling

Standardize ASP.NET Core API error handling by mapping domain failures to RFC 7807 ProblemDetails responses and centralizing unhandled exceptions in a global exception handler. This ensures clients receive consistent, safe 4xx and 5xx payloads.

The Result pattern uses a typed `Result<TValue, TError>` structure to represent expected domain outcomes without throwing exceptions. It enables explicit, type-safe error handling flows for normal application logic.

Map typed domain errors to HTTP responses by defining discriminated error records like NotFound or Conflict, then translating them into typed HTTP responses within an HTTP boundary exception handler that emits ProblemDetails.

Use a global exception handler in ASP.NET Core to centralize unhandled exceptions at the HTTP boundary. This keeps service and repository layers clean while ensuring unexpected infrastructure failures emit safe ProblemDetails responses.

Yes, this approach applies to both ASP.NET Core Minimal APIs and controller endpoints. It standardizes failure translation using typed result patterns and ProblemDetails across different endpoint architectures.

Throwing exceptions for normal domain rule violations leaks internal failures and complicates control flow. Using typed result patterns instead allows you to model expected outcomes like validation issues safely without throwing.
