EF 7验证：EF未验证在模型构建器

Question

使用随VS 2015 RC提供的EF 7的版本，当我在OnModelCreating（）中设置它时，我的datacontext无法正确验证“必需”设置

以下是我的DbContext中的代码：

protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            #region Member
            modelBuilder.Entity<Member>()
                            .ForRelational()
                            .Table("Member", "dbo");

            modelBuilder.Entity<Member>()
                        .Key(x => x.Id);

            modelBuilder.Entity<Member>()
                        .Index(x => x.UserName)
                        .Unique();

            modelBuilder.Entity<Member>()
                        .Property(x => x.UserName)
                        .Required();

            modelBuilder.Entity<Member>()
                        .Index(x => x.Moniker)
                        .Unique();

            modelBuilder.Entity<Member>()
                        .Property(x => x.Moniker)

我正在尝试为“代码优先”做数据库第一个选项，我已经使用了一段时间，因为它刚出现并且以前没有遇到过这个问题。

这是我在SQL中的数据表：

USE [Fambase]
GO

/****** Object:  Table [dbo].[Member]    Script Date: 5/17/2015 11:59:52 AM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[Member](
    [Id] [uniqueidentifier] ROWGUIDCOL  NOT NULL,
    [Moniker] [nvarchar](256) NOT NULL,
    [UserName] [nvarchar](256) NOT NULL,
    [TwoFactorEnabled] [bit] NOT NULL,
    [AccessFailedCount] [int] NOT NULL,
    [LockoutEnabled] [bit] NOT NULL,
    [PhoneNumberConfirmed] [bit] NOT NULL,
    [EmailConfirmed] [bit] NOT NULL,

 CONSTRAINT [PK_Member] PRIMARY KEY NONCLUSTERED

    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

ALTER TABLE [dbo].[Member] ADD  CONSTRAINT [DF_Member_Id]  DEFAULT (newsequentialid()) FOR [Id]

如果我在SQL服务器上删除allow null设置，则EF根本不会对其进行评估。如果设置为NO NULL，我会得到您希望从SQL中获得的SQL错误，但EF不会捕获它并将其抛出异常。

这似乎不像预期的那样。

UPDATE 我的基类如下

public class MemberBase : IMemberBase
    {
        public Guid Id { get; set; }
        public string UserName { get; set; }
        public string NormalizedUserName { get; set; }
        public string PasswordHash { get; set; }
        public string Email { get; set; }
        public string NormalizedEmail { get; set; }
        public bool EmailConfirmed { get; set; }
        public string PhoneNumber { get; set; }
        public bool PhoneNumberConfirmed { get; set; }
        public string Moniker { get; set; }
        public string LastName { get; set; }
        public string FirstName { get; set; }
        public string Middle { get; set; }
        public int AccessFailedCount { get; set; }
        public bool LockoutEnabled { get; set; }
        public DateTimeOffset? LockoutEnd { get; set; }
        public Guid? SecurityStamp { get; set; }
        public bool TwoFactorEnabled { get; set; }
    }

实体继承自基类，如下所示：

public class Member : MemberBase, IMember
    {
        #region IAuditable
        public bool IsDeleted { get; set; }
        public bool IsArchived { get; set; }
        public string CreatedBy { get; set; }
        public string ModifiedBy { get; set; }
        public string DeletedBy { get; set; }
        public string ArchivedBy { get; set; }
        public DateTime DateTimeCreated { get; set; }
        public DateTime? DateTimeModified { get; set; }
        public DateTime? DateTimeDeleted { get; set; }
        public DateTime? DateTimeArchived { get; set; }
        public byte[] ConcurrencyStamp { get; set; }
        #endregion

        #region Navigation 
        public virtual ICollection<ExternalLogin> ExternalLogins { get; set; } = new List<ExternalLogin>();
        public virtual ICollection<MemberClaim> Claims { get; set; } = new List<MemberClaim>();
        public virtual ICollection<MemberRole> Roles { get; set; }
        #endregion
    }
