I created Database file with SQL Server Manager 2017 using SQL Server 2014.
So when i try to connect my database file in Visual Studio 2017 with c# i get this error...

Also i don`t have problem when i Use Tools>Connect to Database from Visual Studio

(System.ArgumentException: 'Option not supported.
Parameter name: attachdbfilename')

<

InitializeComponent();
            string cs = @"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\PC\Desktop\Database\Database.mdf;Integrated Security=True;Connect Timeout=30";
            MySqlConnection con = new MySqlConnection(cs); //error here
            con.Open();
