Interface IHasRowVersion
- Namespace

Optimistic-concurrency token mapped onto PostgreSQL's xmin system column by Npgsql.
EF Core uses it to detect concurrent writes — DBConcurrencyException
surfaces as DbUpdateConcurrencyException on conflict.
public interface IHasRowVersion- Extension Methods
Remarks
No real column is created in the schema; Npgsql maps the property to the system column. Required on every projection view so parallel projection writes stay safe — without an optimistic-concurrency token, a slower projection-worker can overwrite a faster one's committed result with stale state.
Properties
RowVersion
Current row version as read from xmin. Set by EF Core on save.
