2. Agenda
Motivation
OWIN
Project K
Demo

3. Motivation - history 1996 – ASP 2002 – ASP.NET 2008 – ASP.NET MVC
2010 – ASP.NET Web Pages
2012 – ASP.NET Web API, SignalR
2014 – ASP.NET 5
Other stacks: Spring, Rails, Sinatra, Django, Node, Go, …

4. Motivation System.Web basis for * web WebForms bundled Regression bugs
We fix one bug and open new ones
Monolithic architecture
Slow release cycle

5. Motivation Performance IIS stays Evolutionary steps: MVC, WebAPI
“IIS is the fastest web server, as long you don’t load System.Web”
Evolutionary steps: MVC, WebAPI
Released out-of-band
Move from big server apps to smaller client/device centric apps, microservices architecture, mobile clients, REST
Cloud, Docker, cross-platform
Web based IDEs, lightweight IDEs (Sublime, Atom)

6. Motivation
Simplicity

8. OWIN Open Web Interface for dot Net
Defines interface between app components
Decouples app from framework, host and server
Open standard
Not revolution but evolution, influenced by other stacks

9. OWIN SPEC using AppFunc = Func<
IDictionary<string, object>, // Environment       
Task>; // Done

10. OWIN/KATANA Architecture
HOST (w3wp.exe, OwinHost.exe, …)
SERVER (http.sys, IIS)
Request
Middleware
(logging)
Middleware
(auth)
Application
(Web API)
Response

11. OWIN SPECS Community standard
No more System.Web, just dictionary of environment variables (request, response, etc)
Async
Microsofts implementation: Katana
v1-3 is in ASP.NET vCurrent
v4 is vNext
MVC 6, WebAPI, SignalR
Helios, Kestrel, Nowin

12. VNEXT Project K: KRE, KLR, KPM, KVM 2 frameworks:
Full CLR
Core CLR: cross-platform, bin-deployable, ~11MB
Started as OWIN-based, now it’s OWIN - compatible
Faster dev cycle (features shipped as packages, framework as part of an app)
DevOps responsible for security patching!
More control (zero day sec. patches, pull vs push model)
Perf: startup time, memory (>90% reduction), modular

13. VNEXT KIA .SLN .CSPROJ GLOBAL.ASAX ASSEMBLY.CS WEB.CONFIG
PACKAGES.CONFIG
