3. THE HISTORY
Membership 101

4. PREVIOUS MEMBERSHIP SYSTEMS
 ASP.NET Membership
 ASP.NET Simple Membership
 ASP.NET Universal Providers

5. ASP.NET MEMBERSHIP
 Design to solve common membership requirements in 2005
 Form Authentication + SQL Server database
 Limitations




Database schema was designed for SQL Server – CANNOT CHANGE
Profile Provider API is too complicated
Provider system allow to change backing data store, but only Relational Database
Form Authentication won’t work nicely with OWIN

6. ASP.NET SIMPLE MEMBERSHIP
 Developed as a membership system for ASP.NET Web Pages
 Shipped with Web Matrix and Visual Studio 2010 SP1
 Limitations
 Hard to persist membership system data in a non-relational store
 No OWIN
 Doesn’t work well with existing ASP.NET Membership providers. Not extensible.

7. ASP.NET UNIVERSAL PROVIDERS
 Developed to make it possible to persist membership information in Windows
Azure SQL Database (work with SQL Server Compact too)
 Built on Entity Framework Code First, which means it can be used to persist data
in any store supported by EF.
 Database schema cleaned up a lot
 Still built on ASP.NET Membership infrastructure hence same limitations
 Still using Form Authentication for log-in and log-out

8. ASP.NET IDENTITY
The Next Generation Membership System

9. ASP.NET IDENTITY
 One ASP.NET Identity System
 Ease of plugging in profile data about the user
 Persistence Control
 Unit Testability
 Role Provider

10. ASP.NET IDENTITY
 Claims Based
 Social Login Providers
 Windows Azure Active Directory
 OWIN Integration
 NuGet Package

11. OWIN
Open Web Interface for .NET

13. OWIN
 Open Web Interface for .NET
 Defines a standard interface between .NET web servers and web applications
 Goal
 To decouple server and application
 Open source ecosystem of .NET web development tools
 Official website
http://owin.org
 Source code
http://github.com/owin/owin
 Specification (OWIN v1.0.0)
http://owin.org/spec/owin-1.0.0.html

14. OWIN – WTH?
 OWIN is NOT technology
 OWIN is a simple specification that describes how components in a HTTP pipeline
should communicate
 What is in the communication between components is specific to each
component
 OWIN is a community-owned specification, not an implementation
 Inspired by the benefits achieved by Rack () in the Ruby community
 New components could be more easily developed and consumed
 Applications could be more easily ported between hosts and potentially entire
platforms/operating systems
