Assembly: Microsoft.VisualStudio.Shell.12.0 (in Microsoft.VisualStudio.Shell.12.0.dll)
public override void Unregister( RegistrationAttribute.RegistrationContext context )
- Type: Microsoft.VisualStudio.Shell.RegistrationAttribute.RegistrationContext
[in] A RegistrationAttribute.RegistrationContext object used to remove registry keys and to log progress.
This method is called to remove all of the registry entries created by the Register method. Typically, a program such as regpkg.exe reads a specified assembly and looks for all attributes that inherit from the RegistrationAttribute. Regpkg.exe then instantiates each attribute, supplying the appropriate parameters that were specified when the attribute was compiled. Finally, regpkg.exe calls the method on the newly created object to cause all of the appropriate registry keys and entries to be removed. This is done as part of an uninstall process or when Clean Solution is selected from the Build menu.
Note that this method is an override of and specific to the managed package framework (MPF) RegistrationAttribute class.
