If you’ve read a few posts from my blog you’ll probably see that I’ve done a bit of work in the .Net world. My day job requires me to use the .Net Framework for server side programming. I’ve spent a lot of time using C# and enjoy the language.

Here’s a working Plunker too, which shows injecting both a string value (in the HTML) and a value that lives on the controller’s scope:
