Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
When implemented in a derived class, represents the beginning of the LoadIfChanged phase. The LoadIfChanged phase occurs when state data is loaded into the persistence provider from the persistence store, and the state data in the persistence store has been changed.

virtual IAsyncResult ^ BeginLoadIfChanged(TimeSpan timeout, System::Object ^ instanceToken, AsyncCallback ^ callback, System::Object ^ state);public virtual IAsyncResult BeginLoadIfChanged (TimeSpan timeout, object instanceToken, AsyncCallback callback, object state);abstract member BeginLoadIfChanged : TimeSpan * obj * AsyncCallback * obj -> IAsyncResult
override this.BeginLoadIfChanged : TimeSpan * obj * AsyncCallback * obj -> IAsyncResultPublic Overridable Function BeginLoadIfChanged (timeout As TimeSpan, instanceToken As Object, callback As AsyncCallback, state As Object) As IAsyncResultParameters
- timeout
- TimeSpan
The time period after which the persistence provider aborts this attempt.
- instanceToken
- Object
The token returned by a previous Create(Object, TimeSpan) or Update(Object, TimeSpan) that represents the current state held by the caller.
- callback
- AsyncCallback
The method to be called when the operation is completed.
- state
- Object
A user-provided object that distinguishes this particular asynchronous operation from other operations.
Returns
The state of the BeginLoadIfChanged(TimeSpan, Object, AsyncCallback, Object) asynchronous method call.
