Important

Informs Visual Studio that the VSPackage provides an object that can be created from the ILocalRegistryinterface. This class cannot be inherited.

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.
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
Constructors
| ProvideObjectAttribute(Type) |
This constructor creates a new ProvideObjectAttribute object with the given object type. |
Properties
| ObjectType |
The ObjectType property returns the object type set in the constructor. |
| RegisterUsing |
Select between specifying the Codebase entry or the Assembly entry in the registry. This can be overriden during registration |
| TypeId |
Override the TypeID property in order to let the RegistrationAttribute derived classes to work with System.ComponentModel.TypeDescriptor.GetAttributes(...). An attribute derived from this one will have to override this property only if it needs a better control on the instances that can be applied to a class. (Inherited from RegistrationAttribute) |
Methods
| GetPackageRegKeyPath(Guid) |
Gets the registry path (relative to the registry root of the application) of the VSPackage. (Inherited from RegistrationAttribute) |
| Register(RegistrationAttribute+RegistrationContext) |
Provides registration information about a VSPackage when called by an external registration tool such as regpkg.exe. For more information, see Registering VSPackages. |
| Unregister(RegistrationAttribute+RegistrationContext) |
Unregisters this attribute. |
