Which are the namespaces in localization and globalization?

There are 2 most important namespaces:-

1)System.Globalization - It contains classes that define culture-related information, including the country/region, language, the calendars in use, the format patterns for dates, currency and numbers, and the sort order for strings.

2)System.Resources - It provides classes and interfaces which allow developers to store, create and manage various culture-specific resources used in an application. With this namespace you can read a resource file and show it accordingly to the user's culture.
