In the .NET space the overwhelming majority of web projects are built with ASP.NET in one form or another. But there are alternatives. Alternatives that offer other approaches, and supports other ways of thinking.Alternatives that are open source. Altenratives that run on Mono. Maybe one of those alternatives is the better fit for your next project - except if you don't know about them you will never know. In this code heavy talk I'll show the same sample application in the three Open Source .NET web frameworks FubuMVC, OpenRasta, and Nancy. You will not become an expert at anything by attending this talk - but you may discover just the right web framework for your next project.

1. Three web frameworks
All .NET

2. Thanks to the sponsors

3. Who Am I?
• Lead Software Architect @ Mjølner Informatics
• Denmark
• Husband and Father
• Some who enjoys
– Clean code
– TDD’ing
– When Denmarks wins at football
– Simplicity
– Whisky

4. Why?
• There are alternatives to ASP.NET
– Even on .NET
– Know them!
• Style matters
• Tradeoffs, tradeoffs, tradeoffs
– Conventions <-----> explicitness
– DRY <-----> separation of concerns
– Abstract <-----> concrete

5. Why?
• Run anywhere
• IoC/DI to the bone
• Embrace HTTP
• OSS and community driven

6. What will you learn?
A taste of some alternatives
• FubuMVC
• OpenRasta
• Nancy

7. Sample

8. FubuMVC – At a glance
• One Model In One Model Out
– Aka OMIOMO
– Aka Russian Doll
• Convention over Configuration
• Really cool built-in diagnostics
• Everything is POCOs

9. FubuMVC – ShortUrl Overview
GET “/” • No params
HomeController
• Returns HomeViewModel
.get_Home
HomeView.cshtml • Takes HomeViewModel

10. FubuMVC – ShortUrl Overview
POST “/” • UrlShorteningModel
HomeController • Takes UrlShorteningModel
.post_Home • Returns UrlShorteningViewModel
post_url_result.cshtml • Takes UrlShorteningVM

11. FubuMVC – ShortUrl Overview
GET “/42”
• ShortenedUrlModel
• Takes ShortenedUrlMode
HomeController.get_Url
• Returns FubuContinuation

12. FubuMVC
Show me the code!

13. OpenRasta– At a glance
• Three things:
– Resources
– Handlers
– Codecs
• Automatic conneg
• Everything is POCOs

14. OpenRasta – Shorturl Overview
• Resource:
– “/”
GET “/” POST “/” GET “/42”
– “/{shortenedUrl}”
– Home

15. OpenRasta – Shorturl Overview
• Handler
– HomeHandler
Home resource
HomeHandler

16. OpenRasta – Shorturl Overview
GET “/” POST “/” GET “/42”
• “Codecs”
Home resource
– WebForms viewengine HomeHandler
– Form data

17. OpenRasta
Show me the code!

18. Nancy– At a glance
• Lightweight, low ceremony
– Just works
– But easily swappable
– DSLs
• Built in diagnostics
• Automatic conneg
• Testability is first class

19. Nancy – Shorturl Overview
• Modules
– ShortUrlModule
HTTP Handler
Routes Response
request function

20. Nancy – Shorturl Overview
• Routes
– Get[“/”]
– Post[“/”] HTTP Handler
Routes Response
request function
– Get[“/{shortenedUrl}”]

21. Nancy – Shorturl Overview
HTTP Handler
Routes Response
request function
• A lambda for each

22. Nancy
Show me the code!

23. Why, again?
 There are alternatives to ASP.NET
 Know them!
 Style matters
 Tradeoffs, tradeoffs, tradeoffs

24. What might you have learned?
A taste of some altenatives
• FubuMVC
– OMIOMU
• OpenRasta
– Resources, Handlers, Codecs
• Nancy
– DSL

25. FubuMVC, OpenRasta, Nancy
WHEN, WHAT, WHERE?
