Db Prepare Async(CancellationToken) Command.
Asynchronously creates a prepared (or compiled) version of the command on the data source.
public virtual System.Threading.Tasks.Task PrepareAsync (System.Threading.CancellationToken cancellationToken = null);
abstract member PrepareAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task override this.PrepareAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task
An optional token to cancel the asynchronous operation. The default value is None.
The default implementation of this asynchronous method delegates to its synchronous counterpart and returns a completed
Task, potentially blocking the calling thread.
Data providers that support asynchronous programming should override the default implementation using asynchronous I/O operations.
