To be successful mobile app for global market, localization of the app is very important aspect. In Silverlight and WPF, you would achieve the same using CultureInfo and resx files to separate out string resources of different cultures.

In this article, we will go through different techniques of localization of string and image resources.

We all know that DataBinding is one of the most powerful concept of WPF. So, today I thought to write something on how to troubleshoot data binding related issues while working with any XAML based application.
