The ProvideObjectAttribute type exposes the following members.

Constructors

	Name	Description
	ProvideObjectAttribute	This constructor creates a new ProvideObjectAttribute object with the given object type.

Properties

	Name	Description
	ObjectType	The ObjectType property returns the object type set in the constructor.
	RegisterUsing	Gets or sets the registration method.
	TypeId	Gets the current instance of this attribute. (Inherited from RegistrationAttribute.)

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	Register	Provides registration information about a VSPackage when called by an external registration tool such as regpkg.exe. For more information, see Registering VSPackages. (Overrides RegistrationAttribute.Register(RegistrationAttribute.RegistrationContext).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Unregister	Removes registration information about a VSPackage when called by an external registration tool such as regpkg.exe. For more information, see Registering VSPackages. (Overrides RegistrationAttribute.Unregister(RegistrationAttribute.RegistrationContext).)

Explicit Interface Implementations

	Name	Description
	System#Runtime#InteropServices#_Attribute#GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	System#Runtime#InteropServices#_Attribute#GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	System#Runtime#InteropServices#_Attribute#GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	System#Runtime#InteropServices#_Attribute#Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

When to Call

Apply the ProvideObjectAttribute attribute to your Microsoft.VisualStudio.Package-derived class if it provides an object that can be created from the ILocalRegistryinterface.

Basic Usage

The ProvideObjectAttribute class informs Visual Studio that it provides an object that can be created from the ILocalRegistryinterface. Always use this attribute rather than registering objects globally under the HKEY_CLASSES_ROOT\CLSID section of the registry. Use the ProvideObjectAttribute, to modify a Microsoft.VisualStudio.Package-derived class, or a class that implements IVsPackage.

This attribute class is only used to provide data for external registration tools like regpkg.exe. It does not have any effect on the run-time behavior of the VSPackage. For more information, see Registering VSPackages.

Note

C# automatically appends the word "Attribute" to the name of any attribute class. In C# code, refer to this attribute as ProvideObject.

Registry Entries

The following registry entries are created by the ProvideObjectAttribute class:
<VSROOT>\CLSID\{ObjectGuid}
<VSROOT>\CLSID\{ObjectGuid}\@=ObjectType.FullName
<VSROOT>\CLSID\{ObjectGuid}\InprocServer32=mscoree.dll
<VSROOT>\CLSID\{ObjectGuid}\Class=ObjectType.FullName
<VSROOT>\CLSID\{ObjectGuid}\Assembly=ObjectType.Assembly.FullName
<VSROOT>\CLSID\{ObjectGuid}\ThreadingModel=Both
<VSROOT>\CLSID\{PackageGuid}\CodeBase=context.CodeBase

Examples

You can find implementations of the ProvideObjectAttribute class in the managed samples. The standard location for this and all other attributes used for automatic registration is adjacent to the implementation of the Microsoft.VisualStudio.Package class in VsPkg.cs, VsPkg.vb, or VsPkg.cpp, depending on the language used in the sample.

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.
