public abstract UpdateCheck UpdateCheck { get; }

Property Value

An UpdateCheck enum.

Remarks

If the class does not have a version member (IsVersion set to true), detection is done by comparing original member values with the current database state.

The UpdateCheck property determines how LINQ to SQL implements conflict detection under optimistic concurrency. Only those members with this property set to Always or WhenChanged are considered during conflict detection.
