Survival, Inquiry, Sophistication

3. Survival, Inquiry, Sophistication
1. How can we eat?
2. Why do we eat?
3. Where shall we have lunch?
“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

6. Why C#?
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

7. Hey Dude - Javascript – it’s Amazeballs
