The type or name of the namespace "DataSetExtensions" does not exist in the namespace "System.Data" (do you miss the assembly reference?)

Question

I know this is a common error, but I have the correct link to System.Data.DataSetExtensions.dll added to the project, and my project is a SQL CLR project built for .net 4.5, and I get an error on the following line:

using System.Data.DataSetExtensions;

I also checked the properties for the dll and is referencing the correct version for dll 4.5, so what else could be causing this problem? Is this a problem with SQL CLR projects?
