3. Little bit of History OWIN MVC ASP Classic Core Web API Web Forms
Lets try to understand motivations
Classic – just a templating lang
Webforms – apps will be big monolithic integrated systems
RoR came, MVC become popular
SPA and JS heavy apps were getting traction
Owin – simplification and community based re-architecture of web stack
Core – MS started with owin effort, went x-plat, bought xamarin
Web Forms

4. The Language 1.0 released 2002 2.0 – generics 3.0 – lambda, LINQ
4.0 – dynamic, concurrency
5.0 – async
