3. What is Katana? Microsoft's implementation of OWIN components
OWIN is a web server abstraction
OWIN is a community standard

4. What was the Problem?
It's a question of putting things on other things
What is your web app based on?
MVC, Web API, SignalR
What are those frameworks based on?
System.Web? HttpListener? Third party?
How is that a problem?
Each framework provides hosting code for each server
Some frameworks are coupled to a specific server
Not all adapters play well together

5. What is a Solution? Make a server abstraction
Each frameworks can run on the server abstraction
One adapter per server now covers all frameworks
There are other nice side-effects
A server abstraction is great for unit testing
It opens the door for making "thinner" hosting options

6. Demos Hello World Things that are like http handlers
Things that are like http modules
If you're using the new MVC5 template, you're using katana already
Running on http listener
