Public Overridable Function GetDatabaseValuesAsync (Optional cancellationToken As CancellationToken = Nothing) As Task(Of PropertyValues)

Parameters

CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns

A task that represents the asynchronous operation. The task result contains the store values, or null if the entity does not exist in the database.
