public IAsyncResult BeginTransactedCancel (Guid instanceId, AsyncCallback callback, object state);

[<System.ServiceModel.OperationContract(AsyncPattern=true, Name="TransactedCancel")>]
abstract member BeginTransactedCancel : Guid * AsyncCallback * obj -> IAsyncResult

Public Function BeginTransactedCancel (instanceId As Guid, callback As AsyncCallback, state As Object) As IAsyncResult
