  6. ASP.NET Asynchronous Page lifecycle Init Load PreRender Async calls PreRender Complete

  7. Synchronous vsAnsynchronous • Synchronous • Call method => Wait for result • One method at a time • Easy to program/understand • Asynchronous • Call method => Return right away • Result / method completion provided via callback • Run several methods at the same time • Scalability • Harder to program

  8. Asynchronizing the Application demo

  9. Async support in C# vNext • “Looks like” synchronous programming • Uses Task/Task<T> behind the courtains • Two new contextual keywords • async marks a method as asynchrnous • await yields control while waiting on a task to complete

  10. Modernizing the Application demo

  11. Summary • ASP.NET Page lifecycle • Load test your application • Asynchronous pages • Asynchronous actions • Async support in C# vNext
