Have project references and extender projects changed in 0807?  I am deploying a new server with the newest version of K2, upgrading from Hotfix 2.  I got everything installed and setup buy upgrading to 0803 then to 0807 and running the latest update pack.  I downloaded one of the solutions from the database to update the Design Templates but it appears 0807 is handling the references to extender projects differently.  I'm getting a few warnings when I open:

"Warning 1 Could not resolve project reference "........Desktop
manewRMA Paid Auth.sln". VSCSWinWF-45eaf6f6b6124004b1915bfb626eff1d"

"Warning 2 The referenced component 'Context-45eaf6f6b6124004b1915bfb626eff1d' could not be found"

when I look at the project references I see 'Context-45eaf6f6b6124004b1915bfb626eff1d' is showing unresolved.  If I open the same file with 0803 the references are fine.  I've attached a screenshot to help explain when I'm seeing.  Any help would be greatly appreciated...I need to know that I will be able to update my current processes before switching to 0807.
