Question

When should I use Neutral culture? What is the necessary for it? why not force using Specific Culture?

Can someone tell me a real time scenario, where Neutral cultures are used than Specific Culture?

Answer 1

From MSDN:

A neutral culture is a culture that is associated with a language but not with a country or region. It differs from a specific culture, which is a culture that is associated with both a language and a country or region. For example, fr is the name for the neutral French culture, while fr-FR is the name for the French culture in France.

If this property returns false, the culture is either a specific culture or the invariant culture.

Example In my case I speak Spanish from Spain however I have a friend that He speaks Spanish from Mexico. The both speak Spanish but there are some words different so if you want a good translation you should use Spanish from Spain (ES-ES) for Spanish people and Spanish from Mexico (ES-MX) for Mexican people.

In some cases you can't translate your software (GUI) to all languages and cultures so you use only a Spanish translation for all people who speak Spanish (Spain,Mexico,Argentina,USA,Philippines ...)
