Injecting SignInManager through DI causing issues when trying to resolve about aspnetcore.identity.mongodbcore

[estradege]

Hello, I have the same problem when I update from 2.1.1 to 3.1.1. Have you find a fix for this?

Hi, thanks for reaching out, have you compared your project with the sample project?

Here's the link to the startup class:
https://github.com/alexandre-spieser/AspNetCore.Identity.MongoDbCore/blob/master/sample/MongoIdentitySample.Mvc/Startup.cs

            services.AddIdentityCore<ApplicationUser>()
                    .AddRoles<MongoIdentityRole>()
                    .AddMongoDbStores<ApplicationUser, MongoIdentityRole, Guid>(settings.ConnectionString, settings.DatabaseName)
                    .AddSignInManager()
                    .AddDefaultTokenProviders();

There were breaking changes in 3.1.0: https://github.com/alexandre-spieser/AspNetCore.Identity.MongoDbCore/releases/tag/3.1.0

Hi, thanks for your reply.
I'm using ConfigureMongoDbIdentity :

services.ConfigureMongoDbIdentity<User, Role, ObjectId>(new MongoDbIdentityConfiguration
{
  MongoDbSettings = new MongoDbSettings
  {
      ...
  },
  IdentityOptionsAction = options =>
  {
      ...
  }
})
.AddSignInManager()
.AddDefaultTokenProviders();

Adding AddSignInManager() and AddDefaultTokenProviders() resolve the DI error but, raise a new one during the login process :
No sign-in authentication handlers are registered. Did you forget to call AddAuthentication().AddCookie("Identity.Application",...)?

Thank's for your help

hmm that seems to be related to the auth middleware missing, are you calling AddAuthentication() ?

            services.AddIdentityCore<ApplicationUser>()
                    .AddRoles<MongoIdentityRole>()
                    .AddMongoDbStores<ApplicationUser, MongoIdentityRole, Guid>(settings.ConnectionString, settings.DatabaseName)
                    .AddSignInManager()
                    .AddDefaultTokenProviders();

will not handle authentication for you, referring to the sample startup class I linked, on line 44 you'll find

            services.AddAuthentication(o =>
           {
               o.DefaultScheme = IdentityConstants.ApplicationScheme;
               o.DefaultSignInScheme = IdentityConstants.ExternalScheme;
           })
           .AddIdentityCookies(o => { });

and later on

            services.ConfigureApplicationCookie(options =>
            {
                // Cookie settings
                options.Cookie.HttpOnly = true;
                options.ExpireTimeSpan = TimeSpan.FromMinutes(5);

                options.LoginPath = "/Account/Login";
                options.SlidingExpiration = true;
            });

Please compare https://github.com/alexandre-spieser/AspNetCore.Identity.MongoDbCore/blob/master/sample/MongoIdentitySample.Mvc/Startup.cs with your setup.
