# From asp:UpdatePanel to a Angular implementation

This post was in draft mode from around a 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 an `asp:UpdatePanel` to an Angular implementation and the 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:

2.  The Angular JS Website

3.  Using RESTful web services with Angular
