Windows Phone - How to use Resource Files

Resource Files in Windows phone has the similar concepts as it was in Web Forms. It can be used for localization as well as store string values to be used across your apps. Resource files are a nice way to reduce hardcoding strings inside your application code.
The default resource file added to your solution when the project is created is "AppResources.resx" which is in the "Resources" folder at the root of your project folder hierarchy. This default file is called the "neutral language resource" because it is the fallback resource file even in localization scenarios.

Note: As in web forms and win forms, each culture has its own resource file, with the culture suffixed to the filename (AppResources.en-US.resx). We will discuss more on localization scenarios in another post.

Below is the code to dynamically bind your resource to XAML page element's properties.

"{Binding Path=LocalizedResources.ApplicationHeader, Source={StaticResource LocalizedStrings}}"

For example if we want to bind a string resource to the Text property of TextBlock Control:

<TextBlock Text="{Binding Path=LocalizedResources.ApplicationHeader, Source={StaticResource LocalizedStrings}}" />
