## Overview
Similar to the issue encountered in this case:

Renaming / Refactoring a custom View Controller isn't reflected in the storyboard. I was able to reproduce this as follows:

1. Create a new iOS Single View app (comes with a storyboard and a ViewController already.)
2. Open ViewController.cs, and refactor the class definition of "ViewController" to a different name, like "AnotherViewController"

## Result 
It seemed like the references to the ViewController were renamed everywhere except for the storyboard itself. The ViewController in the storyboard did not seem to be updated accordingly. I also didn't see the warning ("yield") sign you referred to, though perhaps that was due to my test case being very minimal somehow. (Nothing really depended on the bits I changed.)

I agree that this isn't a bug, but I also think it's not the best user experience. I can't really think of a scenario where you would refactor the UIViewController class name, but wouldn't want the value in the codebehind updated. I'm not sure we can really control that, as this part of the refactoring engine is out of our control. Our best bet may be something like a lint rule that will look for inconsistencies between a registered class name and it's _actual_ name.
