Token Based Authentication using ASP.NET Web API 2, Owin, AspNet.Identity.MongoDB and mongocsharpdriver - mongodb

Question

+after successfully implementing Token Based Authentication using ASP.NET Web API 2, Owin, and Identity, i wished to change my implementation to use MongoDB instead of MSSQL with Entity Framework, with the help of this application here....truth be said, i dont fully understand how this should be done, but at least i know what i want my application to behave. i want to follow this IMPLEMENTATION HERE, using AspNet.Identity.MongoDB and mongocsharpdriver...and so far, here,s what I've done:
Account Controller
using Microsoft.AspNet.Identity;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Http;
using withMongoDB.HelperClasses.Services;
using withMongoDB.Models.Account;
namespace withMongoDB.Controllers
{
[RoutePrefix("api/Account")]
public class AccountsController : ApiController
{
AccountsService _accountsService = new AccountsService();
// POST api/Account/Register
[AllowAnonymous]
[Route("Register")]
public async Task<IHttpActionResult> Register(UserModel userModel)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
await _accountsService.Register(userModel);
return Ok();
}
private IHttpActionResult GetErrorResult(IdentityResult result)
{
if (result == null)
{
return InternalServerError();
}
if (!result.Succeeded)
{
if (result.Errors != null)
{
foreach (string error in result.Errors)
{
ModelState.AddModelError("", error);
}
}
if (ModelState.IsValid)
{
// No ModelState errors are available to send, so just return an empty BadRequest.
return BadRequest();
}
return BadRequest(ModelState);
}
return null;
}
}
}
then the register method from the controller should be taken by the accounts Service
using AspNet.Identity.MongoDB;
using Microsoft.AspNet.Identity;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Web;
using withMongoDB.Models.Account;
namespace withMongoDB.HelperClasses.Services
{
public class AccountsService
{
private readonly MongoAccountsConnectionHelper<UserProfile> _accounts;
public AccountsService()
{
_accounts = new MongoAccountsConnectionHelper<UserProfile>();
}
public async Task<IdentityResult> Register(UserModel userModel)
{
var userprofile = new UserProfile
{
UserName = userModel.UserName
};
var result = await _accounts.CreateAsync(userprofile, userModel.Password);
return result;
}
}
}
and finally the MongoAccountsConnectionHelper takes the result of the accounts service class to mongo database....
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace withMongoDB.HelperClasses
{
using AspNet.Identity.MongoDB;
//using Entities;
using MongoDB.Bson;
using MongoDB.Bson.Serialization.Conventions;
using MongoDB.Driver;
using System.Configuration;
using withMongoDB.Models.Account;
public class MongoAccountsConnectionHelper
{
private readonly MongoCollection<UserProfile> userProfileCollection;
public MongoDatabase Database { get; private set; }
public MongoAccountsConnectionHelper()
{
var pack = new ConventionPack()
{
new CamelCaseElementNameConvention(),
new EnumRepresentationConvention(BsonType.String)
};
ConventionRegistry.Register("CamelCaseConvensions", pack, t => true);
var mongoUrlBuilder = new MongoConnectionStringBuilder(ConfigurationManager.ConnectionStrings["MongoDB"].ConnectionString);
Database = new MongoClient().GetServer().GetDatabase(mongoUrlBuilder.DatabaseName);
userProfileCollection = Database.GetCollection<UserProfile>("users");
}
public MongoCollection<UserProfile> Users
{
get { return userProfileCollection; }
}
}
}
any help, tips, ideas, or opinions will be highly appreciated....{should i consider alternatives like MembershipReboot and IdentityReboot by brockallen?}

To do it smoothly, you need first to remove the dependency on "Microsoft.AspNet.Identity.EntityFramework", by providing your own user class/table (which should implements IUser as a minimum), and Also you need to implement the UserManager class (which should imeplements UserManager, and finally you need to implement the UserStore class (which should implement IUserStore as minimum) where T is the Id type in the User Table.
Once you done the above, then it is the UserStore where you can change to use MongoDB.
Hope that helps.
