ASP.NET Core MVC exception when using AddSignInManager

I am using ASP.NET Core MVC 3.0 API project. I am using Microsoft.AspNetCore.Identity v3.0

In the Startup.cs, inside the ConfigureServices method, when I type the below and run the application, I get an exception:

var builder = services.AddIdentityCore<AppUser>();
var identityBuilder = new IdentityBuilder(builder.UserType, builder.Services);
identityBuilder.AddEntityFrameworkStores<DataContext>();
identityBuilder.AddSignInManager<SignInManager<AppUser>>();

The AppUser class is something like this:

using Microsoft.AspNetCore.Identity;

namespace Domain
{
    public class AppUser : IdentityUser
    {
        public string DisplayName { get; set; }
    }
}

The exception I am getting is this:

Unhandled exception. System.AggregateException: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Microsoft.AspNetCore.Identity.ISecurityStampValidator Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.SecurityStampValidator`1[Domain.AppUser]': Unable to resolve service for type 'Microsoft.AspNetCore.Authentication.ISystemClock' while attempting to activate 'Microsoft.AspNetCore.Identity.SecurityStampValidator`1[Domain.AppUser]'.)

Any idea what I am doing wrong?

Solution

  • It's better to use AddDefaultIdentity which help you register the services like SignInManager . You can refer to below steps :

    1. Edit project file to install packages :

      <Project Sdk="Microsoft.NET.Sdk.Web">

    <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    </PropertyGroup>

    <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.0.0">
        <PrivateAssets>all</PrivateAssets>
        <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    </ItemGroup>

</Project>

    2. Create DataContext :

      public class DataContext : IdentityDbContext<AppUser>
{
    public DataContext(DbContextOptions<DataContext> options)
        : base(options)
    {
    }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        // Customize the ASP.NET Identity model and override the defaults if needed.
        // For example, you can rename the ASP.NET Identity table names and more.
        // Add your customizations after calling base.OnModelCreating(builder);
    }
}

    3. Startup.cs :

      services.AddDbContext<DataContext>(options =>
    options.UseSqlServer(
        Configuration.GetConnectionString("DefaultConnection")));

services.AddDefaultIdentity<AppUser>()
.AddEntityFrameworkStores<DataContext>();

    4. Inject SignInManager :

      private readonly UserManager<AppUser> _userManager;
private readonly SignInManager<AppUser> _signInManager;
private readonly DataContext _context; 

public WeatherForecastController(UserManager<AppUser> userManager,SignInManager<AppUser> signInManager, DataContext dbContext)
{
    _userManager = userManager;
    _signInManager = signInManager;
    _context = dbContext;

}

    And use like :

    await _signInManager.SignInAsync(user, isPersistent: false);
