Presentation given at Vic.Net User Group in January 2012

Mobile devices like tablets and phones are quickly becoming the primary way people access the web. So why do so many websites still provide a horrible mobile experience?
With ASP.NET MVC, it's easier than ever to literally put your site in the palm of everyone's hand. MVC 3 has many features that allow you to target mobile devices with different layouts and even content. The recent developer preview of MVC 4 makes things even easier and shows that Microsoft is really thinking about web-enabled devices.
In this demo-heavy session, I'll look at the particular challenges with writing sites for mobile devices, and I’ll show some different techniques and third-party libraries that make targeting mobile devices easy, both in MVC3 and in the Developer Preview of MVC4.
If you saw my talk at DDD Brisbane, rest assured I’ll be delving much deeper into the best way to target mobile sites and I’ll focus more on what MVC 4 will bring to the table.

20. CSS Media Queries
Supported by most mobile

User-agent sniffing
25. Top Tips
If starting from scratch:

2. Never use flash or mouseover
events
3. Don’t redirect or change the URL
If modifying for mobile:
1. Start with general changes and get
more specific
