注漿RoleManager導致錯誤首次

Question

第一件事，我的問題是與此類似SO link，但不一樣的

我會通過微軟的身份樣本。我只用用戶身份驗證開始它，它工作。我刪除了數據庫，因爲我想先使用數據庫。現在我正在嘗試加入角色。

我的設置是這樣的用戶（無工作角色）和角色（沒有工作）：

我的DB實體設置爲這樣：

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

    protected override void OnModelCreating(ModelBuilder builder) 
    { 
     base.OnModelCreating(builder); 

     builder.Entity<ApplicationUser>(e => 
     { 
      e.ToTable("User").HasKey(x => x.Id); 
      e.Property(x => x.Id).HasColumnName("UserId"); 
     }); 

     builder.Entity<IdentityRole<int>>(e => 
     { 
      e.ToTable("Role").HasKey(x => x.Id); 
      e.Property(x => x.Id).HasColumnName("RoleId"); 
     }); 

和我的情況下，用戶設置（我想用原來的IdentityRole保持）

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, IdentityRole<int>, int> 
{ 
} 
public class ApplicationUser : IdentityUser<int> 
{ 
} 

在ConfigureServices：

services.AddIdentity<ApplicationUser, IdentityRole<int>>() 
    .AddEntityFrameworkStores<ApplicationDbContext, int>() 
    .AddDefaultTokenProviders(); 

中的AccountController，我嘗試這樣做：

[Authorize] 
public class AccountController : Controller 
{ 
    private readonly UserManager<ApplicationUser> _userManager; 
    private readonly RoleManager<IdentityRole> _roleManager; 
    private readonly SignInManager<ApplicationUser> _signInManager; 
    private readonly IEmailSender _emailSender; 
    private readonly ISmsSender _smsSender; 
    private readonly ILogger _logger; 

    public AccountController(
     UserManager<ApplicationUser> userManager, 
     RoleManager<IdentityRole> roleManager, 
     SignInManager<ApplicationUser> signInManager, 
     IEmailSender emailSender, 
     ISmsSender smsSender, 
     ILoggerFactory loggerFactory) 
    { 
     _userManager = userManager; 
     _roleManager = roleManager; 
     _signInManager = signInManager; 
     _emailSender = emailSender; 
     _smsSender = smsSender; 
     _logger = loggerFactory.CreateLogger<AccountController>(); 
    } 

的應用程序仍然加載瀏覽器和它記得，我在之前已經登錄，但是當我嘗試註銷例如，我得到這個錯誤：

InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.RoleManager`1[MyProj.Web.Models.MyViewModels.ApplicationRole]' while attempting to activate 'MyProj.Web.Controllers.AccountController'.

Answer 1

替換RoleManager<IdentityRole>通過RoleManager<IdentityRole<int>>它應該工作。
