You implement structured error handling in .NET APIs by creating explicit result objects for both successful operations and specific validation failures, translating these typed results into HTTP responses at API endpoints.

You return validation errors without exceptions by mapping specific failures like duplicate emails into distinct, typed result objects, ensuring the API contract communicates structured errors predictably rather than misusing exceptions for control flow.

Use explicit results instead of exceptions for expected outcomes like validation failures in .NET applications, applying pattern-matching at application manager boundaries to handle positive, negative, and error-path scenarios predictably.

Yes, the explicit result pattern integrates into existing .NET services by applying result object creation at service boundaries and translating those structured results into HTTP responses at API endpoints without external dependencies.

A limitation of explicit result objects in .NET is the requirement to manually validate positive, negative, and error-path handling at boundaries, demanding strict pattern-matching discipline to avoid unhandled structured errors.
