  Hello,
  
  After updating my controls to the new Q2 2011 trial Telerik controls for Silverlight, I am now receiving a Catastrophic failure error message as described below:
  
  Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
  
  The version I updated to is version 2011.2.712.1040
  
  However, when I roll back to version 2011.1.315.1040 I am able to run my project just fine. Am I missing something in the upgrade?
  
  FYI, the line where the catastrophic failure occurs is:
  
  RadRibbonTab rrt = new RadRibbonTab();
  
  Thanks,
  
  Patrick

  Hello Patrick,
  
  The issue might be caused if you are referencing both the Telerik.Widnows.Controls.RibbonBar.dll and the Telerik.Widnows.Controls.RibbonView.dll assembly.
  
  Due to the many known limitationd of the RibbonBar we decided that it would be best to provide a new implementation of the control - RadRibbonView. It basically keeps the RadRibbonBar API but it significantly improves its functionality, databinding and design time support. You can find more info about the differences between the two controls here.
  
  The new RadRibbonView control is defined in the Telerik.Widnows.Controls.RibbonView.dll assembly and using both assemblies in the same project can cause issues. However, since I am not sure if this is indeed the reason and we haven't received other similar reprorts I wanted to ask you to please elaborate on your scenario. If you can send us a sample project reproducing the issue, we will be able to further investigate it. Thank you in advance for your cooperation.
  
  All the best,

  Tina-
  
  In using only either the RadRibbonBar or RadRibbonView I am unable to compile my current project.
  
  Is there a major difference between the two that was not mentioned in the blog post?
  
  Thanks,
  
  Patrick

  Hello Patrick,
  
  Both controls share mostly the same API, although there are a few differences. The blog post describes the main advantages of the new control rather than specific API differences. However, the main difference in the controls' API is the way the Contextual Groups are defined. You can find more info about the ContextualGroups implementation in the RadRibbonView control here.
  
  Keeping that in mind I still don't think your issues come from this. You say that you cannot use neither controls in your application and this is why it might be best to try to narrow down the cause for the exception. I'd suggest you to use the ‘remove and try’ approach - remove parts of the code and check if the issue reproduces without it. Keep doing this till you find the cause for the problem.
  
  If this approach doesn't help, you can send us a sample project reproducing the exceptions you get and we will further investigate the case and get back to you with possible solutions.
  
  Best wishes,
