I just ran into this again:
---------------------------
Server Explorer
---------------------------
Unable to add data connection.

Could not load file or assembly 'Microsoft.SqlServer.Management.Sdk.Sfc, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
---------------------------
OK
---------------------------

I thought I downloaded all the packages I needed the last time. What do I have to do to make this go away????
