  • Enhanced Problem Details — Extend ProblemDetails with structured error codes and messages.
  • Result Endpoint Filter — Automatically convert Result<T> return values to 200 OK or 400 BadRequest.
  • API Versioning — Pre-configured URL segment and header-based versioning.
  • Swagger — Easy setup with versioning support, enum schema filters, and custom schema IDs.
