[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.

String String String String

[in] The name of the language. This name is used in the registry for registry key and entry names.

Int32 Int32 Int32 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.


using Microsoft.VisualStudio.Shell;  

namespace MyLanguagePackage  
    internal class MyConstants  
        public const string languageName           = "MyLanguage";  
        public const int    languageNameResourceID = 106;  

    [ProvideLanguageService(typeof(MyLanguageService),           // Required  
                            MyConstants.languageName,            // Required  
                            MyConstants.languageNameResourceID,  // Required  
        // Optional language service properties  
        CodeSense             = true,  // General IntelliSense support  
        RequestStockColors    = false, // Custom colorable items  
        EnableASyncCompletion = true,  // supports background parsing  
        MatchBraces           = true,  // Match braces on command  
        MatchBracesAtCaret    = true   // Match braces while typing  

    class MyLanguagePackage  


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.
