如何首先使用代码向Identity默认表AspNetUsers添加多对多关系?

我是Identity框架和Code First方法的新手。现在我在VS 2015上创建一个新的MVC5项目时使用默认项目。

我运行项目时生成的默认表格很好,但我希望它与其他项目一起生成一个名为tbSkills(Id,SkillName)的新表格,并且它必须与AspNetUsers有多对多的关系。

那么我要写的地方和内容要做到这一点?

ps:我按照教程后也将Id类型从字符串更改为int,它运行正常。

这是我在 IdentityModels.cs 文件中的 ApplicationUser 类中的最后一次尝试:

public class ApplicationUser : IdentityUser<int, MyUserLogin, MyUserRole, MyUserClaim>, IUser<int>
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, int> 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;
    }

    // // This following is my added code 
    public ApplicationUser()
    {
        Skills = new HashSet<tbSkill>();
    }

    public virtual ICollection<tbSkill> Skills { get; set; }
}

public class tbSkill
{
    public tbSkill()
    {
        Users = new HashSet<ApplicationUser>();
    }

    public int Id;
    public string SkillName;

    public virtual ICollection<ApplicationUser> Users { get; set; }
}

它以此错误结束:

我已经研究过很多文章,但没有成功。

尝试添加技能ID

public class ApplicationUser : IdentityUser<int, MyUserLogin, MyUserRole, MyUserClaim>, IUser<int>
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, int> 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;
    }

    // // This following is my added code 
    public ApplicationUser()
    {
        Skills = new HashSet<tbSkill>();
    }
    public int SkillId {get;set;}
    public virtual ICollection<tbSkill> Skills { get; set; }
}
