Problems with roles

Well I'm following this tutorial that was suggested by my teacher to understand the work with roles Roles

The problem is I did everything step by step right but in the last step I can’t get it working because it says: Default parameter 'value' for context must be a compile time constant I tried everything and I don’t know why it does not work. If someone can give a hint to solve this I would appreciate a lot.

Home Controller

using (var context = new ApplicationDbContext())
{
    var roleStore = new RoleStore<IdentityRole>(context);
    var roleManager = new RoleManager<IdentityRole>(roleStore);

    roleManager.Create(new IdentityRole("Admin"));

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

    var user = userManager.FindByEmail("[email protected]");
    userManager.AddToRole(user.Id, "Admin");
    context.SaveChanges();
}

I believe the problem is with var context = new ApplicationDbContext(). C# expects default values to be "compile time constants," which includes things like number and string literals, and excludes new instances of classes or returns from method calls. The simplest way I can think of to pull off what you are trying is to replace the argument with ApplicationDbContext context = null (null can be the default value because it is a compile time constant) and add in the line to the method body if(context == null){ context = new ApplicationDbContext(); }
