issue: Closing the connection closes the reader as well.

public virtual IDataReader ExecSprocReader(string sprocName, IDbDataParameter[] dataParams){
IDbCommand cmd = this.ConfigureSproc(sprocName, dataParams);
IDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);

cmd.Connection.Close(); <-------Here -------------------

return dr;
}
