I'm having trouble with a simple Xamarin Studio Storyboards concept. See screenshots below for visuals and see the [downloadable source code here](https://www.dropbox.com/s/n2pxrmrmxo8so28/Storyboard.Manual_StackOverflow.zip?dl=0). 

Let's say I have a NavigationController with MainViewController on it. This is visible in my storyboard. I want a button which, when pressed, brings up a new NavigationController with RedViewController. I also want RedViewController on the same storyboard as the MainViewController. In this project, I tried to do that but for some reason when I do a:

```
var myStoryboard = AppDelegate.Storyboard;
// Instatiating View Controller with Storyboard ID 'StuffViewController'
RedViewController = myStoryboard.InstantiateViewController ("RedViewController") as RedViewController;
RedViewController.ModalTransitionStyle = UIModalTransitionStyle.CoverVertical;
this.PresentViewController(RedViewController, true, null);

```

the RedViewController doesn't have it's Navigation controller with it. When presented RedViewController's Navigation Controller is null! What am I doing wrong there?

Now when I created a NavigationController & BlueViewController in a totally seperate storyboard it works fine. When I press the Blue Button it goes to the BlueViewController and correctly shows it's NavigationController. Why is this one working but the other one not? The only difference that I can see is that they are on separate Storyboards.

```
UIStoryboard storyBoard = UIStoryboard.FromName ("BlueStoryboard", null);
UIViewController controller = storyBoard.InstantiateInitialViewController () as UIViewController;
controller.ModalTransitionStyle = UIModalTransitionStyle.CoverVertical;
this.PresentViewController (controller, true, null);

```

ViewController that can present a new NavigationController & ViewController ViewController called "Red" with a navigation bar
