BeginUpdate(Object, TimeSpan, Boolean, AsyncCallback, Object)
Begins an asynchronous operation to update instance state information in the persistence store using the parameters passed. This operation locks the instance in the persistence store if the value of the unlockInstance parameter is true.

- instance
- Object
The instance whose state information is being updated in the persistence store.
- timeout
- TimeSpan
The interval in which the operation must complete without timing out.
- unlockInstance
- Boolean
true if the instance must be locked after the instance state is updated in the persistence store; otherwise false.
- callback
- AsyncCallback
The delegate that receives the notification when the operation completes.
- state
- Object
The state information about the asynchronous operation.
Returns
The status of an asynchronous operation.

BeginUpdate(Object, TimeSpan, AsyncCallback, Object)
Begins an asynchronous operation to update instance state information in the persistence store using the parameters passed. This operation does not unlock the instance in the instance store.

- instance
- Object
The instance whose state information is being updated in the persistence store.
- timeout
- TimeSpan
The interval in which the operation must complete without timing out.
- callback
- AsyncCallback
The delegate that receives the notification when the operation is completed.
- state
- Object
The state information about the asynchronous operation.
Returns
The status of an asynchronous operation.
Remarks
This method calls into the BeginUpdate method and passes a false value for the unlockInstance parameter.
