Answer 1

In version 1.50.4 I was able to call connection.QuerySingle<int>(query,params)

Answer 2

I was able to call ExecuteScalar< T > with version 1.42.0

    public Boolean BeforeToday(DateTime dateInQuestion)
    {
        try
        {
            using (var conn = new SqlConnection(ConnectionString))
            {
                String sql = @"SELECT CONVERT(bit, CASE WHEN getdate() > @dateParameter THEN 1 ELSE 0 END) AS BeforeToday";

                var result = conn.ExecuteScalar<Boolean>(sql, new { dateParameter = dateInQuestion });

                return result;
            }
        }
        catch (Exception)
        {
            return dateInQuestion < DateTime.Now;
        }
    }
