Agenda
Localization, Internationalization & Globalization
• Localization
• Making your application support a specific language/locale.
• Internationalization
• Making your application able to support a range of languages and locales
• Globalization
• The combination of Internationalization and Localization
• Language & Locale

ServiceProcess
• System.Globalization
Core Locale services (Date/Time, Currency, Language Processing etc.)
• System.ResourceMulti-Lingual Resource Services
• System.TextCore character conversion Services. (To/From Unicode)
System.Globalization
• Culture-aware String Services
• Casing, Comparison, Collation, Segmentation, Enumeration etc.
• Date-Time Formatting
• dd/mm/yy, mm/dd/yyyy etc.
• Numeric Formatting
• 12,000,000 and 12.000.000
• Calendar Support
• Gregorian, non-gregorian
System.Globalization.CultureInfo
CultureInfo
CurrentUICulture
CurrentCulture
• Information about specific cultures i.e
<LanguageCode>-<RegionCode>
en-US es-ES fr-FR
CurrentUICulture : meant to cover the localization (a.k.a. localisation, a.k.a. translation) of Windows into other languages.
CurrentCulture : allows a user to take any language version of Windows (even if it is not their native language) and see defaults for date formats and number formats and order of text in sorted lists that make sense to them.

Fallback mechanism used to locate appropriate resources
•Attempt to load “en-CA” resource assemble
•If not available, load “en” assembly
•If not available, load default application resources
•Else raise an exception

.resx file .resx file
.resource file .resource file
.resource.dll file .resource.dll file
• Resources are defined in XML documents
– RESX Files• Filenames are significant
– Resource.en-US.resx– Resource.en-UK.resx– Resource.en-CA.resx
• Satellite Assemblies– For each language variant
