How to force to use light theme in Windows Phone 7?

Question

In my Windows Phone 7 app, I want to use the light theme, no matter what theme the user sets in the phone. How to do that ?

Do I need to custom the style or theme ? I just want the default light theme.

Thanks

Jeff Wilcox offers a good way to do this using a theme manager he developed.

There is a nice way of replacing the default brushes. Saves you setting Forecolor everywhere.

You'll still need to set the background of the main layout node to the default background brush.

Background="{StaticResource PhoneBackgroundBrush}"

There is no way to force an app to use a specific theme.

The best you can do is create your own style for every control you use and mimic the light theme in your styles.

Beware, this can be a time consuming and tedious task. Be sure to test all pages and all controls in all states when both the light and dark themes have been specified by the user.

I've had to do this (but for the dark theme) and it's not something I'd do again out of choice.
