When implemented in a derived class, begins asynchronous processing of the tracking record.

protected public:
 virtual IAsyncResult ^ BeginTrack(System::Activities::Tracking::TrackingRecord ^ record, TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);

protected internal virtual IAsyncResult BeginTrack (System.Activities.Tracking.TrackingRecord record, TimeSpan timeout, AsyncCallback callback, object state);

abstract member BeginTrack : System.Activities.Tracking.TrackingRecord * TimeSpan * AsyncCallback * obj -> IAsyncResult
override this.BeginTrack : System.Activities.Tracking.TrackingRecord * TimeSpan * AsyncCallback * obj -> IAsyncResult

Protected Friend Overridable Function BeginTrack (record As TrackingRecord, timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

record: TrackingRecord

The generated tracking record.

timeout: TimeSpan

The time period after which the provider aborts the attempt.

callback: AsyncCallback

The method to be called on completion of the operation.

state: Object

A user-defined object that uniquely identifies this asynchronous operation.

Returns

IAsyncResult

The result of the operation.

Remarks

Participants are expected to begin a job to process the records and return an IAsyncResult that the workflow runtime uses to wait for completion. The default implementation is to call Track and return a Completed status.
