Question

我已经在前面的项目中通过ApplicationUser模型向aspnetusers添加了一个列，一切正常。但是现在在项目后面，当我尝试添加另一个项目时，我得到了：错误号：207，状态：1，类：16 <---。

模型：

public class ApplicationUser : IdentityUser
{   //Added before
    public int Credits { get; set; }
    //What i wanna add now
    public DateTime TimeofCreditDeposit { get; set; }

    public IList<Bet> Bets { get; set; }
}

上下文：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

    public virtual DbSet<Match> Match { get; set; }
    public virtual DbSet<Bet> Bet { get; set; }
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        builder.Entity<Match>()
            .HasMany(b => b.Bets)
            .WithOne(m => m.Match);

        builder.Entity<ApplicationUser>()
            .HasMany(b => b.Bets)
            .WithOne(u => u.User);


    }
}

我在PMC中收到的整个消息太长了，无法在此处分享，但是在开始时它说了某些列名称无效：

尝试向aspnetusers添加一列，但在添加迁移时收到错误207
