Implements

IDataAccessAdapterFetchDataReaderAsync(IRetrievalQuery, CommandBehavior, CancellationToken)
Remarks
Advanced functionality: be aware that the datareader returned is open, and the dataaccessadapter's connection is also open. It can be, if the query is set to cache its resultset, that the reader returned is actually a reader over the cached resultset. If you ordered the query to be cached, be sure to pass queryToExecute to the FetchProjection method to cache the resultset.
