Why a DbUpdateConcurrencyException exception occurs in EF Core?
<p>In EF Core, a <code>DbUpdateConcurrencyException</code> occurs to ensure that multiple users don't overwrite each other's data due to the optimistic concurrency strategy.</p> <p>If there is a difference between the data you want to update and the current database value, EF Core raises the <code>DbUpdateConcurrencyException</code> to signal the concurrency conflict. This mechanism helps maintain data integrity in scenarios with concurrent data access.</p>
