Remarks
The base class manages preferences specific to your language service as well as general preferences the user can affect from the Tools -> Options -> Text Editor category.
The following registry entries are specific to language services and are already reflected in properties in the base class. These registry entries are stored in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\<X.Y>\Languages\Language Services\<Language Name>.
<X.Y> is the version of Visual Studio (for example, 8.0 or 8.0Exp).
<Language Name> is the name of your language.

Notes to Implementers
If you have any language-specific properties in addition to those already supported by the base class, you have to derive a class from LanguagePreferences and return an instance of your class from the GetLanguagePreferences method. Be sure to call the Initialize method before returning your language preferences instance. In addition, you must override InitUserPreferences, OnUserPreferencesChanged2, and Apply methods to support accessing your specified properties.
It is assumed that a single instance of the LanguagePreferences object is maintained for your language service. In this way, any changes the user makes to the properties are dynamically updated in your preferences and from there, throughout the language service.
Notes to Callers
An instance of this class is returned from the LanguageService method GetLanguagePreferences. A number of properties are referenced throughout the managed package framework version of the language service classes.
