OWIN&Katana

How many web and application servers can you name that host .Net applications? How many web frameworks exist for building .Net applications? My bet is you can count either number on one hand. One of the goals of OWIN is to change that. We'll explore other goals of OWIN, the Katana library, and build a simple application that's portable across multiple application servers. I'll also show the power of middleware built for OWIN.

4. History Lesson:
5. History Lesson: 2002 ASP.NET Released alongside .Net 1.0
6. History Lesson: 2002 ASP.NET Released alongside .Net 1.0 Optimized for desktop LOB customers
7. History Lesson: 2002 ASP.NET Released alongside .Net 1.0 Optimized for desktop LOB customers Designed to run on IIS with System.Web
8. History Lesson: 2002 ASP.NET Released alongside .Net 1.0 Optimized for desktop LOB customers Designed to run on IIS with System.Web Tightly coupled to IIS
9. History Lesson: 2009 ASP.NET MVC released
10. History Lesson: 2009 ASP.NET MVC released Shipped out of band from .Net framework
11. History Lesson: 2009 ASP.NET MVC released Shipped out of band from .Net framework Still tightly coupled to System.Web, and therefore IIS
12. History Lesson: Late 2010 Work begins on OWIN specification
13. History Lesson: 2012 Web API released
14. History Lesson: 2012 Web API released No dependencies on System.Web
15. History Lesson: 2012 Web API released No dependencies on System.Web Ability to “Self-Host” without IIS
16. History Lesson: 2012 Web API released No dependencies on System.Web Ability to “Self-Host” without IIS Can be hosted on OWIN compatible servers

25. decouple server and application GOALS: - Paraphrased from owin.org portability enabled by reducing the abstraction to as few primitives as possible
26. decouple server and application, encourage simple modules GOALS: - Paraphrased from owin.org
27. decouple server and application, encourage simple modules GOALS: - Paraphrased from owin.org providing a programming model that enables the development of middleware
