ASP .Net Core Identity Role Claims not adding to User

Question

I'm having issues with using Role/Claims.

I have created Roles and given the roles claims. Then assigned these roles to the users, from what I read online this means the User should inherit the Role Claims but they don't. The policy's didn't work and upon further inspection I couldn't see the claims when outputting the user claims via JSON.

All the data is being saved in the database as I can see it.

Role/Claim Seeder

 public static void SeedRolesAndClaims(RoleManager<IdentityRole> roleManager)
    {
        // Create Roles
        IdentityRole adminRole = new IdentityRole("Admin");
        roleManager.CreateAsync(adminRole).Wait();

        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "edit.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "delete.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "create.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "view.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "create.comment")).Wait();

        IdentityRole userRole = new IdentityRole("User");
        roleManager.CreateAsync(userRole).Wait();
        roleManager.AddClaimAsync(userRole, new Claim(ClaimTypes.AuthorizationDecision, "create.comment")).Wait();

    }

User Seeder

ApplicationUser user = new ApplicationUser { UserName = "john@email.com", FirstName = "Admin", LastName = "Smith", Email = "john@email.com" };
        userManager.CreateAsync(user, "Password123*").Wait();
        userManager.AddToRoleAsync(user, "Admin").Wait();

The check i'm doing is

        var claims = User.Claims.Select(claim => new { claim.Type, claim.Value }).ToArray();
        return Json(claims);

Which returns the basic JSON claims for authentication

[{"type":"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier","value":"05bef53e-dd97-41f6-beee-531501cf8598"},{"type":"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name","value":"john@email.com"},{"type":"AspNet.Identity.SecurityStamp","value":"SGS23ZGIY6UYOOL2APWRIZKNT2V6QBJC"}]

I'm not sure what the issue is and have been searching on google/stackoverflow for a while to no prevail.

Any help would be greatly appreciated

If you are using .Net Core 2.1 , it seems you will need to change the default Identity configuration according to this issue .

In .Net Core 2.1 , you could firstly create your own ApplicationUser :

public class ApplicationUser : IdentityUser
{
}

Modify your dbcontext :

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

Configure the identity using the old-style api :

services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(
        Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddRoleManager<RoleManager<IdentityRole>>()
.AddDefaultUI()
.AddDefaultTokenProviders()
.AddEntityFrameworkStores<ApplicationDbContext>();

And seed the user and role like :

private async Task CreateUserRoles(IServiceProvider serviceProvider)
{
    var RoleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
    var UserManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();

    IdentityResult roleResult;
    //Adding Admin Role
    var roleCheck = await RoleManager.RoleExistsAsync("Admin");
    if (!roleCheck)
    {

        IdentityRole adminRole = new IdentityRole("Admin");
        //create the roles and seed them to the database
        roleResult = await RoleManager.CreateAsync(adminRole);

        RoleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "edit.post")).Wait();
        RoleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "delete.post")).Wait();

        ApplicationUser user = new ApplicationUser { UserName = "v-nany@hotmail.com", Email = "v-nany@hotmail.com" };
        UserManager.CreateAsync(user, "xxxxxx").Wait();

        await UserManager.AddToRoleAsync(user, "Admin");
    }

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env ,IServiceProvider serviceProvider)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
        app.UseHsts();
    }

    app.UseHttpsRedirection();
    app.UseStaticFiles();
    app.UseCookiePolicy();

    app.UseAuthentication();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });

    CreateUserRoles(serviceProvider).Wait();
}

At last ,logout and re-signin the account , the claim should be there :

If you are using .Net Core 2.0 , your code should work with the default identity template .
