A code block embedded in a larger document is typically implemented in a language other than the parent document. The language this code block is written in is represented by the IVsContainedLanguage interface for purposes of displaying the code block in the editor. The IVsContainedLanguage provides functionality for syntax highlighting and some interactive support through the text view (possibly to support code reformatting, statement completion, and so on).

Notes to Implementers:

Implement this interface to support a contained language service feature. This interface is typically implemented on its own class as an instance of the interface is returned from a factory.

Notes to Callers:

Obtain this interface implemented on an object that is returned from a call to the GetLanguage method in the IVsContainedLanguageFactory interface.
