What do I need to install to make Data Connections in Server Explorer work?

I must have uninstalled something recently because the Data Connections no longer work. When I try to expand the Tables node, I get this:

Microsoft Visual Studio

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

What do I need to in开发者_JAVA百科stall to make it work?

Using Windows XP, VS2008 SP1

I believe that is a file that gets installed with SQL Server/Express 2008. It's part of SQL Management Objects (SMO).

I would backup any local Databases you want to keep and then uninstall and reinstall SQL Server (and reapply the latest service pack).
