I'm using SQL Server 2005 and Visual Studio 2010.
So, the problem... When I try to add a new data connection to Visual Studio I receive the folowing error message:
Unable to add data connection. Could not load file or assembly 'Microsoft.Sql.Server.Management.Sdk.sfc, Version = 10.0.0.0, Culture=neutral,PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
