Dependency Injection Structuremap ASP.NET Identity MVC 5

Question

I'm using the new ASP.NET MVC 5 Identity framework for authentication. I've traditionally used StructureMap for dependency injection, but I'm having problems wiring it up to work with the new AccountController.

My AccountController constructors look like this:

    public AccountController()
        : this(new UserManager<OmpUser>(new UserStore<OmpUser>(new OmpDbContext())))
    {    

    }

    public AccountController(UserManager<OmpUser> userManager)
    {
        UserManager = userManager;
    }

My StructureMap config looks like this:

public static class IoC {
    public static IContainer Initialize() {
        ObjectFactory.Initialize(x =>
                    {
                        x.Scan(scan =>
                                {
                                    scan.TheCallingAssembly();
                                    scan.WithDefaultConventions();
                                });

                        //x.Register<IUserStore<OmpUser>>(() =>
                        //    new UserStore<OmpUser>(new OmpDbContext()));

                        x.For<OMPEntities>().HttpContextScoped();

                    });
        return ObjectFactory.Container;
    }
}

When I run up the project I get the following error:

Activation error occured while trying to get instance of type AccountController, key ""

Any ideas of how to new up a UserManager object for construction injection? I've tried searching around but can't find much guidance out there.

Answer 1

Add following code to your Container initialize method.

x.For<Microsoft.AspNet.Identity.IUserStore<ApplicationUser>>()
.Use<Microsoft.AspNet.Identity.EntityFramework.UserStore<ApplicationUser>>();

x.For<System.Data.Entity.DbContext>().Use(() => new ApplicationDbContext());

Adding [DefaultConstructor] Attribute will work.

public class AccountController : Controller
{
    private ApplicationSignInManager _signInManager;
    private ApplicationUserManager _userManager;

    [DefaultConstructor]  //This is the attribute you need to add on the constructor
    public AccountController()
    {
    }
   // Other implementations here..........
}

@vikram, this worked for me.

cfg.For<IRoleStore<IdentityRole,string>>().Use<RoleStore<IdentityRole>>();
