Who Am I?

• There are alternatives to ASP.NET – Even on .NET– Know them!

• Style matters

• Tradeoffs, tradeoffs, tradeoffs– Conventions <-----> explicitness– DRY <-----> separation of concerns– Abstract <-----> concrete

Why?

• Run anywhere

• IoC/DI to the bone

• Embrace HTTP

• OSS and community driven

Why?

A taste of some alternatives

• FubuMVC

• OpenRasta

• Nancy

What will you learn?

Sample

• One Model In One Model Out– Aka OMIOMO– Aka Russian Doll

• Convention over Configuration

• Really cool built-in diagnostics

• Everything is POCOs

FubuMVC – At a glance

GET “/” • No params

HomeController.get_Home

• Returns HomeViewModel

HomeView.cshtml • Takes HomeViewModel

FubuMVC – ShortUrl Overview

FubuMVC – ShortUrl Overview

POST “/” • UrlShorteningModel

HomeController.post_Home

• Takes UrlShorteningModel• Returns UrlShorteningViewModel

post_url_result.cshtml • Takes UrlShorteningVM

FubuMVC – ShortUrl Overview

GET “/42” • ShortenedUrlModel

HomeController.get_Url• Takes ShortenedUrlMode• Returns FubuContinuation

FubuMVC

Show me the code!

• Three things:– Resources– Handlers– Codecs

• Automatic conneg

• Everything is POCOs

OpenRasta– At a glance

• Resource:– “/”– “/{shortenedUrl}”– Home

GET “/” POST “/” GET “/42”

OpenRasta – Shorturl Overview

• Handler– HomeHandler

Home resourceHomeHandler

OpenRasta – Shorturl Overview

• “Codecs”– WebForms viewengine– Form data

Home resourceHomeHandler

GET “/” POST “/” GET “/42”

OpenRasta – Shorturl Overview

OpenRasta

Show me the code!

• Lightweight, low ceremony– Just works– But easily swappable– DSLs

• Built in diagnostics

• Automatic conneg

• Testability is first class

Nancy– At a glance

• Modules– ShortUrlModule

HTTP request Routes Handler

Nancy – Shorturl Overview

• Routes– Get[“/”]– Post[“/”]– Get[“/{shortenedUrl}”]

• A lambda for each

Why, again? There are alternatives to ASP.NET

Know them!

Style matters

Tradeoffs, tradeoffs, tradeoffs

• FubuMVC– OMIOMU

• OpenRasta – Resources, Handlers, Codecs

• Nancy– DSL
