C# - Cloud to Mobile Survival, Inquiry, Sophistication

1. How can we eat?

2. Why do we eat?

3. Where shall we have lunch?

Survival, Inquiry, Sophistication

“The History of every major Galactic Civilization tends to pass through three

distinct and recognizable phases, those of Survival, Inquiry and Sophistication,

otherwise known as the How, Why, and Where phases. For instance, the first

phase is characterized by the question 'How can we eat?' the second by the

question 'Why do we eat?' and the third by the question 'Where shall we have

lunch?”

― Douglas Adams, The Restaurant at the End of the Universe

Q&A

On with some engineering…

Shared code across mobile and cloud

“low level”: compiles, typesafe, quick

Native performance

Native look and feel

Testable

Libraries: commercial and open – and nuget!

Generics, Linq, async/await and the future…

You already have: skills, tools, code

Why C#?

Hey Dude - Javascript – it’s Amazeballs

betting too much on HTML5”
