I'm developing a Windows Phone app that functions like the popular Logo Quiz in the App Store.
I know it involves a database to determine whether the answer is correct or not but I do not know how to put it to use, any tutorials are welcome :)
But the real problem is the popUp interface, there are some sample, some tutorials?
And.. better use XNA or XAML?
Thank you all!
XAML is a good option.
As for samples or tutorials, try this from Nokia developer community..
This will give you a good starting point.
