Agenda

Introdution til OWIN og Katana Projektet

• OWIN• Demo ( Get Started with OWIN and Middlewares )• Demo ( Lets do a Hello OWIN self hosted app )• Demo ( Lets add a WebAPI, Signalr , DI - and create a Chat Server

on Azure )• Demo ( VS 2013 SPA Template – Katana Security)

OWIN Open Web Interface for .NETThe goal of OWIN is to decouple server and application and, by being an open standard, stimulate the open source ecosystem of .NET web development tools.

Open Web Interface for .NET

• Interfacing webservers for web applications.

• Simpler Web Development

map.UseCors(CorsOptions.AllowAll);

and many more

app.MapSignalR()app.UseWebApi(config);

HostsKatana {SystemWeb,HttpListener}

Nowin

Uses Owin:Nancy, Signalr, WebAPI,FubuMVC, Simple.Web

Architecture

Specification

• IDictionary<string, object>• "owin.RequestBody“ : stream• "owin.RequestHeaders“ :

dic<str,str[]>• and so forth

• Func<IDictionary<string, object>, Task>;• I/O Friendly and chainable.

Middleware / Applications

• Func<IDictionary<string, object>, Task>;

Host / Server

• IIS / OwinHost.exe• Microsoft.Owin.Host.SystemWe

b• Microsoft.Owin.Host.HttpListen

er

Applications and Middleware

Web Application – A specific application, possibly built on top of a Web Framework, which is run using OWIN compatible Servers.

Middleware – Pass through components that form a pipeline between a server and application to inspect, route, or modify request and response messages for a specific purpose.

DemoGet Started with OWIN and Middlewareshttps://gist.github.com/s093294/6868042 (only show page between 12:00 and 14:00)

public class Startup { public void Configuration(IAppBuilder app) { app.UseWelcomePage(); } }

DemoLets do a Hello OWIN self hosted app. app.Use( (context, next) => { context.Response.ContentType = "text/html"; return context.Response.WriteAsync("Hello Owin World");

});

Katana

VS201x – Tools > Library Package Manager > Package Manager Settings

• MyGet Katana: http://myget.org/F/katana/

• MyGet Owin: http://myget.org/F/owin/

Package Manager Console:

• Get-Package -ListAvailable -preCheck the source code on codeplex

DemoLets add a WebAPI.

///api/channel9?url=http://channel9.msdn.com/Events/Microsoft-Campus-Days/Microsoft-Campus-Days-2013/RSS [RoutePrefix("api/channel9")] public class Channel9Controller : ApiController {

[HttpGet("")] public IHttpActionResult GetEvents(string url) { return new Channel9ActionResult(Request, url); } }
