Connection issues with C# and MySql using Mono.

For a personal project I am trying to use MySQL to access a database I have created which stores images. I am coding my scripts in C# but my connection refuses to open. Here is a snippet of my code (the relevant portion):

 using MySql.Data.MySqlClient;
 
     string cs ="Server=localhost;Database=test;Uid=root;Pwd=password;";
             
             MySqlConnection conn = null;
             MySqlDataReader rdr = null;
     
             try 
             {
                 conn = new MySqlConnection(cs);
                 conn.Open();
             
                 string stm = "SELECT * FROM images";
                 MySqlCommand cmd = new MySqlCommand(stm, conn);
                 rdr = cmd.ExecuteReader();
     
                 while (rdr.Read())
                 {
                    //do stuff
                 }
     
             } catch (Exception ex)
             {
                 print (ex.ToString());
     
             } finally 
             {
                 if (rdr != null) 
                 {
                     rdr.Close();
                 }
     
                 if (conn != null) 
                 {
                     conn.Close();
                 }
             }

I have put in breakpoints and the culprit is the conn.Open() function. At that point it throws an exception:

"System.TypeInitializationException: An exception was thrown by the type initializer for MySql.Data.MySqlClient.MySqlTrace ---> System.MissingMethodException: Method not found: 'System.Configuration.IConfigurationSectionHandler.Create'. at System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection (System.String configKey) [0x00000] in :0 at System.Configuration.ConfigurationManager.GetSection (System.String sectionName) [0x00000] in :0 at System.Configuration.ConfigurationSettings.GetConfig (System.String sectionName) [0x00000] in :0 at System.Diagnostics.DiagnosticsConfiguration.get_Settings () [0x00000] in :0 at System.Diagnostics.TraceSource..ctor (System.String name, SourceLevels sourceLevels) [0x00000] in :0 at System.Diagnostics.TraceSource..ctor (System.String name) [0x00000] in :0 at MySql.Data.MySqlClient.MySqlTrace..cctor () [0x00000] in :0

It sounds to me like an old/mismatched dll but I brought in MySql.Data, I18N, and I18N.West as a couple of solutions suggested while I was googling. I have run out of suggested fixes and I hope someone can help.

EDIT) My database exists according to Workbench.
