<FeatureConnector(GetType(DiagnosticsFeatureConnector))>  _
Public Class DiagnosticsMenuProvider
    Inherits PrimarySelectionContextMenuProvider

        Dim action As New MenuAction("Feature Diagnostics...")

        AddHandler action.Execute, AddressOf action_Execute 

        Items.Add(action)    
    End Sub

    Sub action_Execute(ByVal sender As Object, ByVal e As MenuActionEventArgs) 
        Dim service As IDiagnosticsService = e.Context.Services.GetRequiredService(Of IDiagnosticsService)()

        service.ShowWindow()

    End Sub

End Class

// The DiagnosticsMenuProvider class adds a context menu item
// that displays a dialog box listing the currently running and

        MenuAction action = new MenuAction("Feature Diagnostics...");

        action.Execute += new EventHandler<MenuActionEventArgs>(action_Execute); 

        Items.Add(action);

    void action_Execute(object sender, MenuActionEventArgs e)
    {
        IDiagnosticsService service =
