Importing SvsServiceProvider in VS 2012

I am new to Visual Studio Extensibility and am try to implement one of the
Microsoft Walkthroughs from the VS 2012 SDK (Displaying Statement Complete). I am having some difficulty
with one class in the walkthrough. The problem is that I get a an error that
SVsServiceProvider is not defined. I have imported Microsoft.VisualStudio.Shell.
Any assistance would be greatly appreciated.

    Public Sub VsTextViewCreated(ByVal textViewAdapter As IVsTextView) Implements IVsTextViewCreationListener.VsTextViewCreated
        Dim textView As ITextView = AdapterService.GetWpfTextView(textViewAdapter)
        If textView Is Nothing Then
            Return
        End If

        Dim createCommandHandler As Func(Of TestCompletionCommandHandler) = Function() New TestCompletionCommandHandler(textViewAdapter, textView, Me)
        textView.Properties.GetOrCreateSingletonProperty(createCommandHandler)
    End Sub
End Class
