MySQL 서버에 연결 시도 중 : SQL Server에 연결하는 동안 네트워크 관련 또는 인스턴스 관련 오류가 발생했습니다.

Question

MySQL 서버에 연결하려고하지만 오류 메시지에서 알 수 있듯이 프로그램이 SQL 서버. MySQL에 연결하는 것을 어떻게 변경할 수 있습니까? 또한 매핑을 위해 NHibernate를 사용하고 있습니다. 이것이 문제가되어야합니까? MySQL Connector를 설치하고 References MySQL.Data 및 MySql.Web으로 추가했지만 아무 것도 변경하지 않았습니다.

내 클래스 :

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

using NHibernate; 
using NHibernate.Cfg; 

namespace ConsoleApp1 
{ 
    class Program 
    { 
     public void testMethod() 
     { 
      Configuration config = new Configuration(); 
      config.Configure(); 

      ISessionFactory factory = config.BuildSessionFactory(); 
      ISession session = factory.OpenSession(); 
      ITransaction tx = session.BeginTransaction(); 

      User u = new User(); 
      u.Name = "AAA"; 
      u.Password = "BBB"; 

      session.Save(u); 
      tx.Commit(); 

      session.Close(); 
     } 

     static void Main(string[] args) 
     { 
      Program p = new Program(); 
      p.testMethod(); 
     } 
    } 
}
