Description Prashant Cholachagudda 2014-07-10 08:18:44 UTC
Steps to reproduce

Create a Xamarin.Mac project called 'Alerts', and then

1.	I did a global search/replace to make the namespace in all appropriate files as “Learn.Lynda.Alerts”.
2.	I changed project options (General > Main Settings > Default Namespace) to “Learn.Lynda.Alerts”.
3.	I opened “MainWindow.xib” into Xcode:
a.	I added two buttons.
b.	Using the alternate editor, I Ctrl + Dragged from each button into the MainWindowController.h creating IBAction’s, one for each button.
c.	I saved changes and closed Xcode.

Once you switch to Xamarin Studio the `MainWindow` partial class disappears from MainWindow.designer.cs file, this results in generic Window instance.

Application output
2014-07-08 19:06:59.009 Alerts[12900:2707] Unknown Window class MainWindow in Interface Builder file,
creating generic Window instead

I have tried to reproduce this issue with the steps mentioned on bug description and here is my observations.

I have added two buttons to MainWindow.xib file using the Xcode and added action to the "MainWindowController.h" file using Ctrl+dragged. After adding action to the "MainWindowController.h" file I have save all the file and closed the Xcode and open the "MainWindow.designer.cs" file in XS and observed that it still contains the "MainWindow" partial class.

However, when I try to build the solution , I am getting same error that is mentioned in bug description.

Hey guys, I couldn't reproduce this issue using Xamarin Studio 5.7 (660) and Xamarin.Mac (current Alpha). I think this bug has been fix already so I'm resolving it as fixed, however feel free to reopen it if you still have it.
