Following are some of the feature of the ASP.NET Identity system

    • ASP.NET Identity can be used with all of the ASP.NET frameworks such as ASP.NET MVC, Web Forms, Web Pages, Web API and SignalR
  • Ease of plugging in profile data about the user
    • When you create new users in your application, it is now easy to add extra information about the user. For eg.. if you wanted to add a Birthdate option for users when they Register an account in your application.
    • ASP.NET Identity uses Entity Framework Code First and it is possible to extend the POCO classes.
  • Persistence control
    • By default the ASP.NET Identity system will store all the user information in a database. ASP.NET Identity uses Entity Framework Code First to implement all of its persistence mechanism.
    • If your application requirements are that this information might be stored in a different storage mechanism such as SharePoint, Azure Table Service, No Sql databases etc. it is now possible to plug in different storage providers.
  • Unit testability
    • ASP.NET Identity makes the web application more unit testable. You can write Unit Tests for the parts of your application that use ASP.NET Identity
  • Simple Role provider
    • There is a Simple Role providers which lets you restrict access to parts of your application by Roles. You can easily create Roles such as “Admin” and add Users to Roles.

ASP.NET Identity is used by ASP.NET Web Forms, MVC and SPA templates in Visual Studio 2013. it is also available as Nuget packages on the Nuget gallery

  • Nuget packages
    • Microsoft.Aspnet.Identity.Core
      • This package contains the core interfaces of ASP.NET Identity.
      • core
    • Microsoft.Aspnet.Identity.EntityFramework

      • Transactions support was added to the framework.

 

Sample to add profile data

The following video video(mark 55min) http://channel9.msdn.com/Events/TechEd/NorthAmerica/2013/DEV-B314#fbid=fEhPNbmXE9- gives you a sneak peak into the features.

You can download a sample from https://github.com/rustd/AspnetIdentitySample. This is based on the ASP.NET MVC template that shipped with ASP.NET and Web Tools 2013 Preview Refresh (Supports English version of VS2013 Preview only) Once you have this Preview Refresh installed you can do the same for ASP.NET Web Forms and SPA applications.

Please do stay tuned to this blog for upcoming posts where I will dive into the various other features in this system.

  • @Hani: I have filed a bug for it internally

  • @Daniel: There will be support for this sometime in the future

  • @Martin, @Manpreet, @Koen: There will be blog posts for addressing you scenarios soon

  • @Luiz: The Identity system works with the OWIN middleware for features such as sign on and OAuth authentication. Hence the dependency

  • @Looooooka: There will be a blog post explaining using Roles pretty soon

  • Are there plans to make Microsoft.Aspnet.Identity.AzureStorage   ?

  • I am also waiting for information on how to use the "Role" feature.  I have searched all over the place and cannot find any info.

  • Still waiting for some documentation. Also when will the asp.net mvc 5 templates be updated so they are working with the updated nuget packages?

  • @Martin, we cannot disclose the release dates.  We'll sure have more samples coming.  Do check the sample showed in the post: github.com/.../AspnetIdentitySample, you might gain more answers there.

  • I'd like to see some information on how to use the new system with a Windows 8/8.1 C# app.

  • How can i add role ? Can not find anything.

  • How about one version using the azure infrastructure, like Azure table storage  or ACS?

  • In the RC1 nuget, why does Microsoft.AspNet.Identity.OWin has a dependency on EntityFramework?  Which part still uses EntityFramework?  Want to replace with an Azure Storage only implementation.

  • @sprinkle: This issue will be fixed in the RTM version of the package

  • The video channel9.msdn.com/.../DEV-B314 # fbid = fEhPNbmXE9-shows how to add variables to the user profile.

    And how can you change the user profile variables and update?
