Visual Studio Code – Connection between Visual Studio and MySQL database

I’m one ear in self learning C# and Unity. Currently I’m in casual development of game. I want to store data in database. I have latest version of Visual Studio and MySQL Server Management Studio.

I succesfuly connected my local DB to VS. I’m able to create tables and add parameters manualy, but I’m not able to comunicate with DB via code itself. The code (below) compile without issue. It seems that I have an error in my connectionString, but I triplececked it.

Can you kick me in the right direction?

Screenshot of succesful connection of DB to VS

using System;
using System.Data;
using MySql.Data.MySqlClient;

public class MySQLConnector
{
    public static void Main(string[] arg)
    {
        string connectionString =
            "Server=*servername*;" +
            "Database=*DBname*;" +
            "Uid=AnyBaddy;" 
            ;
        MySqlConnection connection = new MySqlConnection(connectionString);
        try
        {
            connection.Open();
            Console.WriteLine("Connection successful!");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
        finally
        {
            connection.Close();
        }
    }
}

I tryed to create multiple diferent users with different permisions.
I tryed to re/create multiple servers.
I tryed Postgresql instead of SSMS.

    Ok, I changed my code to:

    using Microsoft.Data.SqlClient;

public class SQLConnector
{
    public static void Main(string[] arg)
    {
        string connectionString =
            "Data Source=BaddyPC;" +
            "Initial Catalog=dbname;" +
            "User id=AnyBaddy;" +
            "Password=userpassword;";
        SqlConnection connection = new SqlConnection(connectionString);
        try
        {
            connection.Open();
            Console.WriteLine("Connection successful!");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
        finally
        {
            connection.Close();
        }
    }
}
