Unhandled Exception: System.Reflection.TargetInvocationException

[ZenzCode 0]

So I started a script today, and I wanted to add the MySQL.

So the problem is, that i get this

Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.Common, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Aborted

Error every time I join, because we check for the whitelist.

Here is the code

 

PlayerDatabase:

using System;
using System.Data.Common;
using MySql.Data.MySqlClient;
using GTANetworkAPI;

namespace RPGerman.RPGerman.Database
{
    class PlayerDatabase
    {

        public static string myConnectionString = "SERVER=censored;" + "DATABASE=censored;" + "UID=censored" + "PASSWORD=" + Main.databasePW + ";";
        public static MySqlConnection connection;
        public static MySqlCommand command;
        public static MySqlDataReader reader;

    //SERVER VALUES
    private static int startgeld = 25000;


    public static bool isPlayerWhitelisted(Client player)
    {
        connection = new MySqlConnection(myConnectionString);
        connection.Open();
        command = connection.CreateCommand();
        command.CommandText = "SELECT * FROM whitelist WHERE socialclub = @socialclub";
        command.Parameters.AddWithValue("@socialclub", player.SocialClubName);
        reader = command.ExecuteReader();
        
        while(reader.Read())
        {
            string SocialClubName = reader.GetString("socialclub");
            if(SocialClubName == player.SocialClubName)
            {
                connection.Close();
                return true;
            }
        }
        connection.Close();
        return false;
    }
    }
}

 

JoinEvent:

        [ServerEvent(Event.PlayerConnected)]
        public void PlayerConnected(Client player)
        {
            if(PlayerDatabase.isPlayerWhitelisted(player))
            {
				//do smthg
            }else{
                player.Kick("~r~Du bist nicht auf der Whitelist.");
            }
        }

 

 

Any ideas?
