Possible null reference return.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

Add a 'protected' constructor or the 'static' keyword to the class declaration. (https://rules.sonarsource.com/csharp/RSPEC-1118)

'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.

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

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