2. What is it?
3. C# and the .NET Framework •C# is the language, like Java or Ruby. C# is very similar to Java, but with a lot of improvements. •.NET Framework is the ecosystem (runtime and libraries) • Actually a bit more complex than this, but we’ll ignore that for now.
4. ASP.NET and ASP.NET MVC • ASP.NET is the foundation web library, covering the HTTP protocol. • MVC stands for “Model, View, Controller”, a way of architecting web applications. • ASP.NET MVC is Microsoft’s very slick nice MVC implementation, great for doing “normal” websites and web applications.
5. ASP.NET Web API • ASP.NET Web API is a REST framework built on top of ASP.NET. • Handles automatically: • HTTP status codes and response messages. • Serialisation and deserialization of XML, JSON, BSON, HTML Forms, and more. • Really simple default routing, but arbitrarily complex routing is possible. • Sensible security defaults (ie, prevents SQL injection).

7. Why should I use it?
8. Python. Django.
9. Ruby. Rails. Node.JS.
10. The thing they have in common?
12. Unfortunately, Microsoft products aren’t considered cool.
13. .NET has changed a lot in the last few years.
15. It’s grown up, and it’s cool now.
17. It’s quick, both in development and in production.
18. It’s (mostly) open source. Microsoft has released a lot under FOSS licenses, but what they haven’t has been re-implemented by the Mono project.
19. It has LINQ. “Language Integrated Query” – you’ll never have to write SQL again.
21. It’s self-documenting. I’ll show you this later.
22. Getting Started
23. The cheap way: • Download Visual Studio Express (Windows) or MonoDevelop (Windows, Linux, Mac). • There’s a free version of Xamarin as well if mobile development is your thing.
24. The expensive way: • Buy a license for Visual Studio Professional ($500+). •Buy a license for Xamarin ($25+).
25. Demonstration
