NET6使用EFCORE CodeFirst现有数据库增加新表

1. Add-Migration InitialCreate

2. 注释20230828044500_InitialCreate文件存在的表

    //migrationBuilder.CreateTable(
    //    name: "Device",
    //    columns: table => new
    //    {
    //        ID = table.Column<int>(type: "int", nullable: false)
    //            .Annotation("MySql:ValueGenerationStrategy", MySqlValueGenerationStrategy.IdentityColumn),
    //        UserName = table.Column<string>(type: "longtext", nullable: true)
    //            .Annotation("MySql:CharSet", "utf8mb4"),
    //        StationId = table.Column<string>(type: "longtext", nullable: true)
