You are designing a new .Net application that will be used by clients in a large number of different countries. The application allows company's to store geographical information and then share that information with other company's in different countries. 
When storing this information ready to publish, which culture should you use?

The invariant culture. The invariant culture is ideal for situations where the information is not presented to the end user but may need to be used from many different locals (languages). The invariant culture is a culture-neutral storage format.
