public function ProvideLanguageServiceAttribute(
    languageService : Object, 
    strLanguageName : String, 
    languageResourceID : int


  • languageService
    Type: System.Object
    [in] This is either a string containing a GUID or a type representing the class that implements the language service. The language service GUID is derived from this string or type.
  • strLanguageName
    Type: System.String
    [in] The name of the language. This name is used in the registry for registry key and entry names.
  • languageResourceID
    Type: System.Int32
    [in] The resource ID for the localized version of the language name. This is used to present the language name in dialog boxes and other user interface elements.


The following registry layout shows where each of the required parameters is used.

  Language Services\
      (Default) = reg_sz: [languageService.GUID]
       Package   = reg_sz: [Package GUID]
       LangResID = reg_dword: [languageResourceID]

The [Package GUID] value is automatically obtained from the class that implements the IVsPackage interface in the assembly.

In addition to the required parameters listed in the Parameters section, the constructor also accepts optional named parameters after the required parameters. This is a special form supported only in user-defined attributes. These named parameters correspond to the public properties on this class that have both get and set operators.
