Logging out: Close all opens views, re-open root view OR restart the app

[olegul86]

Hello friends.

Essentially, what I am trying to do is for the user to log out of my application.
I am not at the moment tracking the logged in user throughout the application, so I thought I'd just close all open views and re-open the root view which is the log in window.
I have set my application up according to how it's described in the documentation.

I am using the following:

Application.Current.Windows
    .Cast<Window>()
    .Where(w => w is not RootView)
    .ToList()
    .ForEach(w => w.Close());

RootViewModel viewModel = new RootViewModel(windowManager);

And this works, but I am looking for a better solution. I don't know if this way of doing it will work when I later on implement user tracking in my application.
I would like to implement the Bootstrapper.Launch() method, but by default it's set to protected override void - I don't know how to access it.

A bit of a messy and open question, appreciate any who take the time to write a comment :-)

I'd do something like (completely untested, but you get the general idea):

public class CloseAllWindowsService
{
    private readonly Application application;
    private readonly Action openRootView;

    public CloseAllWindowsService(Application application, Action openRootView)
    {
        this.application = application;
        openRootView = openRootView;
    }

    public void CloseAllWindows()
    {
        foreach (Window window in application.Windows)
        {
            window.Close();
        }

        openRootView();
    }
}

Then in your bootstrapper:

protected override void ConfigureIoC(StyletIoCBuilder builder)
{
     builder.Bind<CloseAllWindowsService>().ToInstance(new CloseAllWindowsService(Application, Launch));
}

Then in your VM:

public class MyViewModel : Screen
{
    private readonly CloseAllWindowsService closeAllWindowsService;

    public MyViewModel(CloseAllWindowsService closeAllWindowsService)
    {
        this.closeAllWindowsService = closeAllWindowsService;
    }

    public void LogOut()
    {
        closeAllWindowsService.CloseAllWindows();
    }
}
