I built this with JS/HTML/CSS but the MathEngine component I built using C# (.winmd) and called into it from the Javascript.
If you have any specific questions about how different parts are implemented, let me know :).
I was just thinking that with the state of the how APIs were last year this would have been very tough to do, so I was wondering if you went the JS route since it was in better shape than XAML.
I actually went the JS route because of my skillset. I was was web-dev before I joined MS and never got into XAML much.
The JS platform was pretty stable from the initial public release, I guess that's because it is built on top of IE which has been around much before Win8 came along.
- Blu was selling the most at $1.99 but the revenue was the most at 3.99 (sold on average more than half of what I sold at 1.99).
- Interestingly enough, it sold much more at 1.99 than at 1.49
I chose to push back to 1.99 for the time-being to increase the # of users.
