问题描述

我已经将代码从ASP.NET Core 2.0升级到了Core 2.1.我创建了一个新的Core 2.1项目，并将代码移到了新项目中.我提供了我的创业公司和ApplicationDbContext

尝试登录时出现以下错误

I get the following error when trying to Log In

无法为"IdentityUser"创建DbSet，因为此类型不是 包含在上下文模型中. Microsoft.EntityFrameworkCore.Internal.InternalDbSet.get_EntityType()

Cannot create a DbSet for 'IdentityUser' because this type is not included in the model for the context. Microsoft.EntityFrameworkCore.Internal.InternalDbSet.get_EntityType()

startup.cs

startup.cs

//Core 2.1
  services.AddDefaultIdentity<IdentityUser>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();            

////Old Core 2.0 Code
  //services.AddIdentity<ApplicationUser, IdentityRole>()
        //    .AddEntityFrameworkStores<ApplicationDbContext>()
        //    .AddDefaultTokenProviders();

ApplicationDbContext.cs

ApplicationDbContext.cs

public partial class ApplicationDbContext : 
    IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> 
 options)
        : base(options)
    {
        Database.EnsureCreated();
     }
 }

我已经阅读了以下Microsoft文章: https://blogs.msdn.microsoft.com/webdev/2018/05/30/asp-net-core-2-1-0-now-available/

I have reviewed the following Microsoft articles : https://blogs.msdn.microsoft.com/webdev/2018/05/30/asp-net-core-2-1-0-now-available/

推荐答案

尝试将public partial class ApplicationDbContext : IdentityDbContext<ApplicationUser>更改为public partial class ApplicationDbContext : IdentityDbContext<IdentityUser>

编译器将使用以下命令生成 DbSet 通用IdentityDbContext<TUser>类提供的类型.

Compiler will generate DbSet with the type provided to generic IdentityDbContext<TUser> class.
