NHibernate.AspNet.Identity

ASP.NET Identity provider that users NHibernate for storage

About this

Purpose

ASP.NET MVC 5 shipped with a new Identity system (in the Microsoft.AspNet.Identity.Core package) in order to support both local login and remote logins via OpenID/OAuth, but only ships with an Entity Framework provider (Microsoft.AspNet.Identity.EntityFramework).

Features

• Drop-in replacement ASP.NET Identity with NHibernate as the backing store.
• Based on same schema requirede by EntityFramework for compatibility model
• Contains the same IdentityUser class used by the EntityFramework provider in the MVC 5 project template.
• Supports additional profile properties on your application's user model.
• Provides UserStore implementation that implements the same interfaces as the EntityFramework version:
  • IUserStore
  • IUserLoginStore
  • IUserRoleStore
  • IUserClaimStore
  • IUserPasswordStore
  • IUserSecurityStampStore

Quick-start guide

These instructions assume you know how to set up NHibernate within an MVC application.

1. Create a new ASP.NET MVC 5 project, choosing the Individual User Accounts authentication type.
2. Remove the Entity Framework packages and replace with NHibernate Identity:

Uninstall-Package Microsoft.AspNet.Identity.EntityFramework
Uninstall-Package EntityFramework
Install-Package NHibernate.AspNet.Identity

3. In ~/Models/IdentityModels.cs:

   • Remove the namespace: Microsoft.AspNet.Identity.EntityFramework
   • Add the namespace: NHibernate.AspNet.Identity
   • Remove the ApplicationDbContext class completely.

4. In ~/Controllers/AccountController.cs

   • Remove the namespace: Microsoft.AspNet.Identity.EntityFramework
   • Add the relevant ISession implementation that will be used by default. This could be from a DI implementation. Note: This isn't mandatory, if you are using a framework that will inject the dependency, you shouldn't need the parameterless constructor.

5. Setup configuration code

NHibernate

	// this assumes you are using the default Identity model of "ApplicationUser"
	var myEntities = new [] {
		typeof(ApplicationUser)
	};
	
    var configuration = new Configuration();
    configuration.Configure("sqlite-nhibernate-config.xml");
    configuration.AddDeserializedMapping(MappingHelper.GetIdentityMappings(myEntities), null);

    var factory = configuration.BuildSessionFactory();
    var session = factory.OpenSession();

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

FluentNHibernate

	// this assumes you are using the default Identity model of "ApplicationUser"
	var myEntities = new [] {
		typeof(ApplicationUser)
	};
	
	var configuration = Fluently.Configure()
	   .Database(/*.....*/)
	   .ExposeConfiguration(cfg => {
	       cfg.AddDeserializedMapping(MappingHelper.GetIdentityMappings(myEntities), null);
		});
	
    var factory = configuration.BuildSessionFactory();
    var session = factory.OpenSession();

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

Special thanks to David Boike whos RavenDB AspNet Identity project gave me the base for jumpstarting the NHibernate provider
