I don`t know what to do to correct this error, pls help ")

I solved the problem by creating an empty constructor in MainWindow.

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
        public MainWindow(IUnityContainer container)
        {
            DataContext = container.Resolve<IMainWindowViewModel>();
            InitializeComponent();
        }
    }

But i wanna know if is possible to use Tabs on a User Control ? Because in the first time a was using the tabs on a UserControl

I think you should implement InterTabClient. In this way you can control creation of MainWindow instance.

Here's mine:

    public class InterTabClient : IInterTabClient
    {
        public INewTabHost<Window> GetNewHost(IInterTabClient interTabClient, object partition, TabablzControl source)
        {
            var view = ServiceLocator.Current.GetInstance<MainWindow>();

            return new NewTabHost<Window>(view, view.Tabs);
        }

        public TabEmptiedResponse TabEmptiedHandler(TabablzControl tabControl, Window window)
        {
            return TabEmptiedResponse.CloseWindowOrLayoutBranch;
        }
    }

In MainWindow:

            <dragablz:TabablzControl.InterTabController>
                <dragablz:InterTabController InterTabClient="{Binding InterTabClient}" />
            </dragablz:TabablzControl.InterTabController>

In MainViewWindowModel: public IInterTabClient InterTabClient { get; } = new InterTabClient();
