Microsoft.SqlServer.Management.Sdk.Sfc 11.0.0.0 Not Found

Hi Group.  

Using the "Connect To Database" button in Server Explorer all goes well until I click the "OK" button in the Add Connection dialog.  When this dialog goes to literally add the connection to Server Explorer I receive the error "Unable to Add connection...file not found".  Note that upon testing the connection with the "Test Connection" button it checks out okay.  The file it states that can't be found is: "Microsoft.SqlServer.Management.Sdk.Sfc, version=11.0.0.0" or one of its dependencies.  

I've tried:

1.  Repairing Visual Studio via Uninstall/Repair
2.  Using SQL's Server Installation Center to confirm all aspects are valid/correct - are
3.  Searching for this error using the filename ...Microsoft.SqlServer.Management.Sdk.Sfc and there are reports of this problem but their error references the file as having version 10; mine references 11 and as well I have completed all of the fixes they suggest with no effect.

I am using Visual Studio 11 Developer Preview.  My thoughts are that in re-installing SQL Server 2008 R2 Express I somehow have lost or changed this file from 11 back to 10 and that VS-11 DP requires version 11.

If I'm right would you know how to obtain this file or how to go about repairing the installation other than how I've tried?  If my assumption is incorrect, how to fix this problem?

Thank you for all input!
