NetCore + Mysql CodeFirst 生成数据库

首先定义领域的模型类，然后配置下面的一些东西，最后执行类

1. 新建Context 继承自 DbContext 

public class EFProjectContext : DbContext
    {
        public EFProjectContext(DbContextOptions options) : base(options)
        {

        } 

        public DbSet
 Addreses { get; set; }
        public DbSet Customers { get; set; } 
    }

　2.在Startup类中获取mysql 连接字符串

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();

            #region 获取数据库连接字符串 
            var connectionString = Configuration.GetConnectionString("DefaultConnection");
            //var builder = new ConfigurationBuilder();
            //builder.SetBasePath(Directory.GetCurrentDirectory());
            //builder.AddJsonFile("appsettings.json");
            //var connectionStringConfig = builder.Build();
            //var connectionString = connectionStringConfig["ConnectionStrings:DefaultConnection"];
            services.AddDbContext(options => options.UseMySQL(connectionString));
            #endregion

            #region IOC

            services.AddTransient, Repository>();
            services.AddTransient();
            #endregion
            #region AutoMapper


            #endregion
        }

　　3. 在appsettings.json中配置 连接字符串

"ConnectionStrings": {
    "DefaultConnection": "Server=localhost;database=netcore_test;uid=root;pwd=root;SslMode=None"
  }

 执行命令:  Add-Migration InitialCreate

　　　　   update-database
