WCFProxyGenerator for VS2012

I have a custom WCF Proxy generator that I've migrated from VS2008 - VS2010 but am unable to use it from VS2012. This is based off the great work over athttp://wcfproxygenerator.codeplex.com/

This key exists for VS2010 but NOT for VS2012 has the WCFProxyGenerator model changed for VS2012? I have been unsucessful so far uncovering any information.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Generators\{FAE04EC1-301F-11D3-BF4B-00C04F79EFBC}\WCF Proxy Generator

This is the registration code that works perfect for VS2010, my assembly is in the GAC - Moving this to the 11.0 Hive did not work.

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\CLSID\{69cf4e9e-c755-408a-b407-117cc3acabeb}]
@="ExceptionHandlingWCFProxyAddin.ExceptionHandlingWCFProxyGenerator"
"InprocServer32"="C:\\Windows\\SysWOW64\\mscoree.dll"
"ThreadingModel"="Both"
"Class"="ExceptionHandlingWCFProxyAddin.ExceptionHandlingWCFProxyGenerator"
"Assembly"="ExceptionHandlingWCFProxyAddin, Version=2.0.0.0, Culture=Neutral, PublicKeyToken=385b6950f1bca43c"

Any thoughts would be greatly appreciated!

Thanks in advance!
