Identity API 2.0 Check if user is admin role on View

Question

Inside the scaffolded partial view _Layout.cshtml is defined the app's navigation bar. I'd like to modify it so that some links are only shown if the logged user is "Admin".

Inside the Seed() method of my Configuration.cs file for migrations, is defined the following:

bool AddUserAndRole(ApplicationDbContext context) {
        IdentityResult ir;

        var rm = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));
        ir = rm.Create(new IdentityRole("Admin"));

        var um = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));

        var user = new ApplicationUser() { UserName = "admin", FirstName = "System", LastName = "Administrator" };
        ir = um.Create(user, "admin");

        if(ir.Succeeded == false) {
            return ir.Succeeded;
        }

        ir = um.AddToRole(user.Id, "Admin");

        return ir.Succeeded;
    }

As you can see, there is a role called "Admin" and the newly created user is added to that role.

That being said, I've tried several ways inside my _Layout.cshmtl to attempt to determine whether the current user is "Admin" or not

@if(Roles.IsUserInRole(User.Identity.Name, "Admin")) { }

@if (User.IsInRole("Admin")) { }

but none seem effective. How do I do that?

Answer 1

@if (User.IsInRole("Admin"))
    {
         <li>@Html.ActionLink("Link Text", "Controller", "Action")</li>
    }

This worked for me.
