This version adds a fallback mechanism to support full localization based both on country/region and language. For more details take a look at the documentation; a sample application that demonstrates this is available in the source code.
About the package content:
This release contains the library as binary as well as a set of sample configurations that demonstrate remote and local text and xaml content and localization. YLAD is already used by multiple applications in the Marketplace and hence considered stable. For more information, consider reading the documentation.
Also, please note that the recommended way of installing the library is to use NuGet (which configures your project references and adds an initial configuration file automatically) - use the package "ylad".
