I need to use Server class which is stored in Microsoft.SqlServer.Smo.dll
I don't see this assembly in usual References dialog. I have found it at C:/Program Files/Microsoft SQL Server/100/SDK/Assemblies
and try to reference from there but Visual Studio throws an error
A reference 'C:/Program Files/Microsoft SQL Server/100/SDK/Assemblies/Microsoft.SqlServer.Smo.dll' could not be added. Please make sure that file is accessible, and that it is a valid assembly or COM component.
What am I doing wrong?
