The Package type exposes the following members.

Constructors

	Name	Description
	Package	Initializes a new instance of Package.

Properties

	Name	Description
	ApplicationRegistryRoot	Gets the root registry key of the current Visual Studio registry hive.
	UserDataPath	Gets the path to user data storage for Visual Studio.
	UserLocalDataPath	Gets the path to local user data storage for Visual Studio.
	UserRegistryRoot	Gets a registry key that can be used to store user data.
	Zombied	Gets a value indicating whether the package in the process of shutdown.

Methods

	Name	Description
	AddOptionKey	Adds a user option key name into the list of option keys.
	CreateInstance	Creates the specified COM object using the Visual Studio's local registry CLSID object.
	CreateTool	Enables derived classes to provide an implementation if necessary.
	CreateToolWindow	Creates a tool window of the specified type with the specified ID.
	Dispose	Releases the resources used by the Package object.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	FindToolWindow	Gets the tool window corresponding to the specified type and ID.
	FindWindowPane	Gets the window pane corresponding to the specified type and ID, and if no window pane of that type exists creates one if told to do so.
	GetAutomationObject	Gets the automation object for the VSPackage.
	GetDialogPage	Gets the requested dialog page.
	GetGlobalService	Gets a service proffered globally by Visual Studio or one of its packages. This is the same as calling GetService() on an instance of a package that proffers no services itself.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetOutputPane	Gets the requested output window.
	GetProviderLocale	Returns the locale associated with this service provider.
	GetService	Gets type-based services from the VSPackage service container.
	GetToolboxItemData	Gets the content of the data format for the specified toolbox item ID and data format.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Initialize	Called when the VSPackage is loaded by Visual Studio.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnLoadOptions	Invoked by the package class when there are options to be read out of the solution file.
	OnSaveOptions	Invoked by the Package class when there are options to be saved to the solution file.
	ParseToolboxResource(TextReader, Guid)	Parses an embedded text resource of appropriate format for information about which items should be added to the Toolbox.
	ParseToolboxResource(TextReader, ResourceManager)	Parses an embedded text resource of appropriate format for information about which items should be added to the Toolbox.
	QueryClose	Called to ask the package if the shell can be closed.
	RegisterEditorFactory	Registers an editor factory with Visual Studio.
	RegisterProjectFactory	Registers a project factory with Visual Studio.
	ShowOptionPage	Displays a specified tools options page.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	ToolboxInitialized	Event generated whenever Visual Studio initializes its Toolbox.
	ToolboxUpgraded	Event generated whenever Visual Studio upgrades its Toolbox.

Explicit Interface Implementations

	Name	Description
	IServiceContainer.AddService(Type, ServiceCreatorCallback)	Infrastructure. Adds the given service to the VSPackage's service container.
	IServiceContainer.AddService(Type, Object)	Infrastructure. Adds the given service to the VSPackage's service container.
	IServiceContainer.AddService(Type, ServiceCreatorCallback, Boolean)	Adds the given service to the service container by means of the specified ServiceCreatorCallback.
	IServiceContainer.AddService(Type, Object, Boolean)	Infrastructure. Adds the given service to the VSPackage's service container.
	IServiceProvider.GetService	Gets the service of the specified type.
	IServiceContainer.RemoveService(Type)	Infrastructure. Removes the given service type from the service container.
	IServiceContainer.RemoveService(Type, Boolean)	Infrastructure. Removes the given service type from the service container, and optionally promotes the removal of the service to parent service containers.
	IOleCommandTarget.Exec	Executes a specified command or displays help for a command.
	IOleCommandTarget.QueryStatus	Queries the object for the status of one or more commands generated by user interface events.
	IServiceProvider.QueryService	Infrastructure. Internal IServiceProvider implementation.
	IVsPackage.Close	Infrastructure. Closes and disposes the package.

	IVsPackage.GetPropertyPage	Infrastructure. Proffers access to the Tools menu Options and the property pages of the Customize Toolbox dialog boxes.
	IVsPackage.QueryClose	Infrastructure. Called to ask the VSPackage if the Visual Studio shell can be closed.
	IVsPackage.ResetDefaults	Infrastructure. Resets Toolbox defaults.
	IVsPackage.SetSite	Infrastructure. Initializes the VSPackage in the Visual Studio environment.
	IVsPersistSolutionOpts.LoadUserOptions	Infrastructure. Loads user options for a given solution.
	IVsPersistSolutionOpts.ReadUserOptions	Infrastructure. Reads user options for a given solution.
	IVsPersistSolutionOpts.SaveUserOptions	Infrastructure. Saves user options for a given solution.

	IVsToolboxItemProvider.GetItemContent	Gets an item.
	IVsToolWindowFactory.CreateToolWindow	Infrastructure. Creates a tool window of the specified type with the specified ID.
	IVsUserSettings.ExportSettings	This method implements the IVsUserSettings Interface used to manage profiles and import/export settings to XML files.
	IVsUserSettings.ImportSettings	Retrieves a VSPackage's configuration using the Visual Studio settings mechanism when a user selects the import option of the Import/Export Settings feature on the IDE’s Tools menu. This method is part of the implementation of the IVsUserSettings interface used to manage profiles and import/export settings to XML files.
	IVsUserSettingsMigration.MigrateSettings	Migrates settings from a previous version.
	IVsUserSettingsQuery.NeedExport

Remarks

The Package class provides a managed implementation of several of the most useful VSIP interfaces. You can create the basic functionality of a VSPackage with relatively little code by deriving from the Package class, overriding some of its methods, and attaching registration attribute classes. The Package class does not provide direct registration support, but it can use attribute classes to supply the necessary registration information to external tools such as RegPkg.exe.

The Package class offers the following services by default. (You can replace them by asking the VSPackage for IServiceContainer, removing them, and adding your own services in their place.)

Package

The package offers itself as a service.
IServiceContainer

Provides the ability to add and remove services. Any service added with "promote" set to true is proffered to Visual Studio through IProfferService. This makes the service global to all VSPackages within Visual Studio. (This service is available only if the VSPackage has already been loaded.)

In addition to these services, Package uses the service architecture of Visual Studio to provide access to any service available through the global service provider.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
