'ArrayParameterTypeDao.Read(NpgsqlTransaction, string, IEnumerable<Guid>, bool, DateTime?)' hides inherited member 'CompoundParameterTypeDao.Read(NpgsqlTransaction, string, IEnumerable<Guid>, bool, DateTime?)'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

'CyclicRatioScaleDao.MapToDto(NpgsqlDataReader)' hides inherited member 'RatioScaleDao.MapToDto(NpgsqlDataReader)'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
