实体框架核心先添加唯一约束代码
我找不到使用属性向字段添加唯一约束的方法: public class User { [Required] public int Id { get; set; } [Required] // [Index("IX_FirstAndSecond", 2, IsUnique = true)] not supported by core public string Email { get; set; } [Required] public string Password { get; set; } } 我正在使用这些软件包: "Microsoft.EntityFrameworkCore": "1.0.1", "Microsoft.EntityFrameworkCore.SqlServer": "1.0.1", "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.0.1", "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final",
