Pull request overview
Updates Microsoft.Extensions.Validation.ValidateContext’s ValidationErrors value type from IEnumerable<string> to IReadOnlyList<string> to better reflect the concrete, materialized error collection shape and avoid exposing potentially lazy / multi-enumeration semantics.
Changes:
- Change
ValidateContext.ValidationErrorstoIReadOnlyDictionary<string, IReadOnlyList<string>>?. - Update internal
_validationErrorsstorage and helper signatures to useIReadOnlyList<string>consistently.
