MembershipCreateUserException: The username supplied is invalid - entity-framework

Question

Im trying to use Facebook registration on my MVC 4 application, but I keep getting this cryptic error System.Web.Security.MembershipCreateUserException: The username supplied is invalid.
when OAuthWebSecurity.CreateOrUpdateAccount(provider, providerUserId, model.UserName); is run
provider = "facebook"
providerUserId = "token-key"
model.Username = "bobsaget"
Everything is basically set back to a default MVC 4 application at this point. Here is the code I am running.
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult ExternalLoginConfirmation(RegisterExternalLoginModel model, string returnUrl)
{
string provider = null;
string providerUserId = null;
if (User.Identity.IsAuthenticated || !OAuthWebSecurity.TryDeserializeProviderUserId(model.ExternalLoginData, out provider, out providerUserId))
{
return RedirectToAction("Manage");
}
if (ModelState.IsValid)
{
// Insert a new user into the database
using (UsersContext db = new UsersContext())
{
UserProfile user = db.UserProfiles.FirstOrDefault(u => u.UserName.ToLower() == model.UserName.ToLower());
// Check if user already exists
if (user == null)
{
// Insert name into the profile table
db.UserProfiles.Add(new UserProfile { UserName = model.UserName});
db.SaveChanges();
db.SaveChanges();
OAuthWebSecurity.CreateOrUpdateAccount(provider, providerUserId, model.UserName);
OAuthWebSecurity.Login(provider, providerUserId, createPersistentCookie: false);
return RedirectToLocal(returnUrl);
}
else
{
ModelState.AddModelError("UserName", "User name already exists. Please enter a different user name.");
}
}
}
ViewBag.ProviderDisplayName = OAuthWebSecurity.GetOAuthClientData(provider).DisplayName;
ViewBag.ReturnUrl = returnUrl;
return View(model);
}
The MembershipAttribute have always been default, except its getting information from web.config.
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute
{
private static SimpleMembershipInitializer _initializer;
private static object _initializerLock = new object();
private static bool _isInitialized;
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
// Ensure ASP.NET Simple Membership is initialized only once per app start
LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
}
private class SimpleMembershipInitializer
{
public SimpleMembershipInitializer()
{
Database.SetInitializer<UsersContext>(null);
try
{
using (var context = new UsersContext())
{
if (!context.Database.Exists())
{
// Create the SimpleMembership database without Entity Framework migration schema
((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
}
}
var i = Config.ConnectionStringName;
WebSecurity.InitializeDatabaseConnection(
Config.ConnectionStringName,
Config.UserTableName,
Config.UsersPrimaryKeyColumnName,
Config.UsersUserNameColumnName,
autoCreateTables: true);
}
catch (Exception ex)
{
throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
}
}
}
}
I have browsed the web, Stackoverflow and even tried to decompile the dll without getting to the root of the problem.
Thanks in advance for your input.

I am not sure but i think you need to make to sure that an entry of user is properly inserted into userprofile table and also the other tables which are required for membership.
