How can you handle optimistic concurrency in Entity Framework Core?

  • Use database locks
  • Use pessimistic concurrency
  • Use timestamps or row version columns
  • Manually update records
Optimistic concurrency in EF Core is typically handled by using timestamps or row version columns in the database. When two users try to update the same record concurrently, EF Core checks if the row version has changed since the data was initially loaded, and if so, it raises a concurrency exception, allowing you to handle the conflict.
