Deprecated. Gets the RFC 4646 standard identification for a language.
Assembly: mscorlib (in mscorlib.dll)
This property and the GetCultureInfoByIetfLanguageTag method are deprecated. Instead of using these elements, the application should use a new CultureInfo object and calls to the Name property. IETF tags and names are identical.
The RFC 4646 standard that is maintained by the Internet Engineering Task Force (IETF) defines an IETF language tag, which provides a uniform means of identifying a language. The format of an IETF language tag is similar to the culture name returned by the Name property, but does not identify a culture uniquely. That is, different cultures share the same IETF language tag if those cultures have identical linguistic characteristics. The linguistic characteristics of a culture are contained in the TextInfo object associated with a CultureInfo object.
An IETF language tag consists of a mandatory language identifier, an optional script identifier, and an optional region identifier.
