Remarks
You can apply the DatabaseAttribute attribute to any strongly typed DataContext declaration.
The DatabaseAttribute attribute is optional. If you use it, you must use the Name property to supply a name.
If you do not apply this attribute and the connection does not specify a name, the database is assumed to have the same name as the DataContext class.
