Asp.net mvc 在web层向现有.NET核心项目添加标识

在web层中，我在

identity

文件夹中有两个类

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

public class ApplicationUser : IdentityUser
{
    public string FullName { get; set; }
}

公共类ApplicationIdentityDbContext:IdentityDbContext

我用PMC成功地尝试了代码和迁移，请确保迁移路径中包含了
ApplicationIdentityDbContext
。我确信ApplicationIdentityDbContext也包含在web层中。我右键单击web层，然后在文件资源管理器中选择打开文件夹，然后我在写迁移。我想可能是你上下文的位置不正确。如果我们使用默认生成的模板，则上下文将位于Data文件夹中，而不是Identity。我处理它，可能是因为我使用了一些旧版本的软件包，thaks for helpfull Comments Application Identity YDBContext。。。{}是无用的，可以中断迁移。
