Attempts to cancel the operation that is associated with the supplied IAsyncResult object.
Assembly: Microsoft.Data.Services.Client (in Microsoft.Data.Services.Client.dll)
The IAsyncResult object passed to the asyncResult parameter is the object returned when an operation is executed asynchronously. For more information, see Asynchronous Operations (WCF Data Services).Until this request is processed, the DataServiceContext instance is not in a predictable state. The DataServiceContext can be safely used when the IsCompleted property of the asyncResult returns a value of true.
