Property Value

Type: System.Boolean

Remarks

Visual Studio can display line numbers for any source file, helping users find particular lines of source. This ability is controlled from the Options dialog box (available from the Tools -> Options menu) with the option Line numbers. If a language service cannot support line numbers for some reason, then the EnableLineNumbers property should be set to false, thereby disabling the Line numbers option.

This property is available to any language service implementation.

The default is true when the corresponding registry entry is accessed through the LanguagePreferences class.

The registry entry looks like this:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[X.Y]\Languages\Language Services\
  [Language Name]\
    EnableLineNumbersOption = reg_dword: 0x00000001

Examples

    [ProvideLanguageService(typeof(MyLanguageService),           // Required
                            MyConstants.languageName,            // Required
                            MyConstants.languageNameResourceID,  // Required
        // Optional language service properties
        EnableLineNumbers = true,  // line numbers are supported
                           )]
