MySQLConnection has no implementation

Question

I'm new to C# and connecting to databases. The problem is: whenever I try to connect to DB by running this code:

        string connparams = "server=127.0.0.1;uid=root;pwd=12345;database=test;";
        try
        {
            MySqlConnection connection = new MySqlConnection(connparams);
        }
        catch (System.ArgumentException me)
        {
            Console.WriteLine(me.ToString());
        }
          connection.Open();
          connection.Close();

I get the window "The application is in break mode" When I take a look at the events window I can see an exception with description "No source code". When I try to see the implementations of functions in MySQLConnection I can see none of them, only declarations. So what should I do/redo/reinstall in order to solve this? Using VS2017, .NET Framework 4.6.1, Connector/NET (MySQL)
