Question

我已按照以下方式使用ApplicationUser而不是创建自己的ApplicationUser。 ApplicationUser来自默认的MVC 5应用程序：

http://blogs.msdn.com/b/webdev/archive/2013/10/20/building-a-simple-todo-application-with-asp-net-identity-and-associating-users-with-todoes.aspx

这是我的public class ApplicationUser : IdentityUser { public async Task<ClaimsIdentity> GenerateUserIdentityAsync( UserManager<ApplicationUser> manager ) { // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType var userIdentity = await manager.CreateIdentityAsync( this, DefaultAuthenticationTypes.ApplicationCookie ); // Add custom user claims here return userIdentity; } public virtual ICollection<Field> Fields { get; set; } }代码：

Field

这是我的public class Field { [Key] public int FieldID { get; set; } // [ForeignKey( "Id" )] // Not sure if i needed this but neither worked public virtual ApplicationUser CreatedBy { get; set; } ...代码：

PM> Add-Migration AddedCreatedByToFields

但是当我运行One or more validation errors were detected during model generation: FieldApplication.Domain.Concrete.IdentityUserLogin: : EntityType 'IdentityUserLogin' has no key defined. Define the key for this EntityType. FieldApplication.Domain.Concrete.IdentityUserRole: : EntityType 'IdentityUserRole' has no key defined. Define the key for this EntityType. IdentityUserLogins: EntityType: EntitySet 'IdentityUserLogins' is based on type 'IdentityUserLogin' that has no keys defined. IdentityUserRoles: EntityType: EntitySet 'IdentityUserRoles' is based on type 'IdentityUserRole' that has no keys defined.时会出现以下错误：

ApplicationUser

任何想法我做错了什么？

旁注

我将{{1}}代码移到了一个名为Domains的独立项目中。我包含了Identity Nuget包来获取其中的命名空间......

我最后放置了这个：

modelBuilder.Entity<IdentityUserLogin>().HasKey<string>( l => l.UserId );
modelBuilder.Entity<IdentityRole>().HasKey<string>( r => r.Id );
modelBuilder.Entity<IdentityUserRole>().HasKey( r => new { r.RoleId, r.UserId } );

进入我的EFDbContext：

    protected override void OnModelCreating( DbModelBuilder modelBuilder )
    {
        // base.OnModelCreating( modelBuilder );
        Precision.ConfigureModelBuilder(modelBuilder);

        modelBuilder.Entity<IdentityUserLogin>().HasKey<string>( l => l.UserId );
        modelBuilder.Entity<IdentityRole>().HasKey<string>( r => r.Id );
        modelBuilder.Entity<IdentityUserRole>().HasKey( r => new { r.RoleId, r.UserId } );
    }

然后我必须运行迁移，然后创建了一整套新表...我最终保留...我删除了默认表。

将表与Microsoft身份用户相关联 - 没有键定义的错误
