I'm getting the following error when trying to retrieve some data from an attached MDF file (SQL Server 2005):
Exception has been thrown by the target of an invocation.

The column does exist on that table.
The code I am using is:
var user = (from record in Repository.SystemUsers
where record.UserName == loginName && record.Source == source
select record).SingleOrDefault();
