Introducing ASP.NET Identity – A membership system for ASP.NET applications

http://blogs.msdn.com/b/webdev/archive/2013/06/27/introducing-asp-net-identity-membership-system-for-asp-net-applications.aspx

Now when creating a new web application with ASP.NET 4.5, we have the new "ASP.NET Identity".

I manage to let my application to use my MSSQL database with the build in register/login/change password functions, but I am not sure how to do other operation like old days ( especially the "ASP.NET Configuration" is gone). Since this is something new, I failed to find any nice guide or I was thinking wrongly.

the "[dbo].[AspNetUsers]" now has the [Id] in nvarchar(128), not the uniqidentifier, but still in GUID format
Membership.GetUser().ProviderUserKey is no longer working, how do I get the Id? (get username by User.Identity.Name then query the [dbo].[AspNetUsers]?"
How to create (manage) roles beside manipulate the database directly? (like the previous System.Web.Security.Roles.CreateRole method)

etc

it would be best if anyone can provide link for a detail introduction about how to implement this "ASP.NET Identity"

Thanks a lot..

Update

I found the Id can be retrived by:
(new System.Linq.SystemCore_EnumerableDebugView(((System.Security.Claims.ClaimsPrincipal)(((System.Web.UI.Page)(this)).User)).Claims)).Items[0].Value

it is in the claim.. but looks not very efficient.

Best Answer

I'm in the same boat. I have found a cleaner way to get the userid

 var identity = new ClaimsIdentity(User.Identity);
 var id = identity.GetUserId();

Azure – Details of customizing ASP.NET Identity (OWIN) use of Entity Framework

Asp.Net Identity has default implementation of storage using EntityFramework.
Microsoft.AspNet.Identity.Core has a list of interfaces, that need to be implemented to store the data where and how you want. These interfaces provide minimum required members and methods.
IdentityManager is the main entry point where you can pass your custom store interface implementation.

IdentityManager(Microsoft.AspNet.Identity.IIdentityStore)

Look this customization for framework (not relating to store/storage, it will guide you further)

Implementing User Confirmation and Password Reset with One ASP.NET Identity

Using ASP.Net Identity in MVC 4

It should be doable, first you basically want to install the 3 packages:

Microsoft.AspNet.Identity.Core
Microsoft.AspNet.Identity.EntityFramework
Microsoft.AspNet.Identity.Owin

You would then need to pull in the associated Owin packages as well:

Owin
Microsoft.Owin
Microsoft.Owin.Security
Microsoft.Owin.Security.Cookies
Microsoft.Owin.Host.SystemWeb

And you would then need to hookup Owin with something like this:

using Microsoft.Owin;
using Owin;

[assembly: OwinStartupAttribute(typeof(WebApplication19.Startup))]
namespace WebApplication19
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
                // Enable the application to use a cookie to store information for the signed in user
                app.UseCookieAuthentication(new CookieAuthenticationOptions
                {
                    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                    LoginPath = new PathString("/Account/Login")
                });
                // Use a cookie to temporarily store information about a user logging in with a third party login provider
                app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
        }
    }
}

You will also have to remove/turn off all of the old membership/forms auth in your app, and switch to using the new identity APIs.
