ASP.net MVC 5：扩展I​​dentityUser类以使用我的用户实体类

Question

我在Asp.net MVC 5中的UserManager类属于

类型

public UserManager<ApplicationUser<MyUser>> UserManager { get; private set; }

在运行时类型为;

{Microsoft.AspNet.Identity.UserManager<app.Models.ApplicationUser<MyCustom.DataAccessLayer.MyUser>>}

当我执行findAsync进行身份验证时。

var user = await UserManager.FindAsync(model.UserName, model.Password);

然后抛出异常System.InvalidOperationException。因为它不是在寻找MyUser实体，所以它寻找ApplicationUser1实体。

The entity type ApplicationUser1 is not part of the model for the current context.

Answer 1

你是否重写OnModelCreating Class？

样品：

protected override void OnModelCreating（DbModelBuilder modelBuilder） {

     base.OnModelCreating(modelBuilder);

     //Map Entities to their tables.
     modelBuilder.Entity<ApplicationUser>().ToTable("MyUser");

}

你应该让实体框架知道应该使用MyUser Entity ApplicationUser实体。
