From asp:UpdatePanel to a Angular implementation

This post was in draft mode from around an year back when I started out with Angular. But thought I'd publish it now than never. They do say "better late than never" :).

I was working on porting a .NET UserControl which used a asp:UpdatePanel to an Angular implementation and following are some of the resources I used. A reminder for myself as much as a list for others.

Justification: 

Why move from asp:UpdatePanel?

With the viewstate switched on, the page was a whopping 21.6 MB. The Angular implementation brought it down to 300 KB and increased the response time drastically.

The resources:

1. Intro to Angular (with some cool videos and tasks)
