Unable to add data connection.Could not load file or assembly 'Microsoft.SqlServer.Management.Sdk.Sfc, Version=,

Few days ago, I installed SQL Server 2005 on my Laptop. I opened up Visual Studio 2008 and tried to connect to SQL Server database. But, I got an error message:

Unable to add data connection.
Could not load file or assembly 'Microsoft.SqlServer.Management.Sdk.Sfc, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.

The solution for the above problem was to :

Install the following from Microsoft SQL Server 2008 Feature Pack RC0, June 2008
- Microsoft SQL Server 2008 Native Client
- Microsoft SQL Server System CLR Types
- Microsoft SQL Server 2008 Management Objects

if you do not have SQL 2008 then these features can be downloaded from:


After installing the components, close and reopen Visual Studio 2008, you should now be able to Add the database through your Server Explorer
