public bool EnableAdvancedMembersOption { get; set; }

Property Value

Type: System.Boolean

Returns true if the Hide Advanced Members option is enabled; otherwise, returns false.

The Options dialog box (available under Tools -> Options menu) shows for languages a general set of options. One of those options is the Hide Advanced Members. When this option is selected, members of a class not normally accessible from a particular place in the source code are not shown when an IntelliSense members list is displayed. The EnableAdvancedMembersOption property determines whether the Hide Advanced Members option is even available for a language. If this property is set to true, then the Hide Advanced Members option can be selected. This property works in conjunction with the HideAdvancedMembersByDefault property which sets the initial state of the Hide Advanced Members option.

This property is available to any language service implementation.

The default is false 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]\
    EnableAdvancedMembersOption = reg_dword: 0x00000001

[ProvideLanguageService(typeof(MyLanguageService),           // Required
                        MyConstants.languageName,            // Required
                        MyConstants.languageNameResourceID,  // Required
    // Optional language service properties
    EnableAdvancedMembersOption = true,  // Always show private members
