VS2012 Add Item Templates for Windows Store apps

Hi,

We have a VisualStudio custom editor associated with a file extension. When the file is added to VS2012 WinRT project I can double click to open the file in our custom editor. However we are not able to add our file to the "Add Item" dialog. It works in both VS2008 and VS2010 C# projects.

We register for "Add Item" through VS registry:

HKLM\Software\Microsoft\VisualStudio\11.0\Projects\{PROJGUID}\AddItemTemplates\TmplateDirs\{PackageGUID}\/1

TemplatesDir="PathToTemplates" (contains vsdir files)

Is there a special registry key/value to add for WinRT registration?

Do we need to add something to the vsdir files?
