BLToolkit Output Parameter in DataAccessor

Question

How to map output parameter in SQL to an out parameter in DataAccessor? I've tried to put Direction.Output attribute, but with no luck. Nonworking sample:

public abstract class DocumentAccessor : DataAccessor<DocumentRecord>
{
    [SprocName("[dbo].[FE_GetDocuments]")]
    public abstract IEnumerable<DocumentRecord> GetDocuments(
        [ParamName("PageIndex")] int pageIndex,
        [ParamName("PageSize")] int pageSize,
        [ParamName("SortColumn")] string sortColumn,
        [ParamName("SortDirection")] string sortDirection,
        [ParamName("TotalCount"), Direction.Output] out int totalCount);
}

Answer 1

Resolved by changing result type to IList<DocumentRecord>. Looks like BLToolkit generates deferred-execution proxy for IEnumerable<T> signature.
