UINavigationController

appdelegate.cs

public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
    window = new UIWindow (UIScreen.MainScreen.Bounds);
    

    UINavigationController rootViewController = new UINavigationController ();

    SomeOtherViewController mainVC = new SomeOtherViewController ();

    rootViewController.PushViewController (mainVC, false);

    window.RootViewController = rootViewController;
            
    window.MakeKeyAndVisible ();
