ORM history know that LINQ to SQL is not Microsoft’s first endeavor at object-relational mapping. Theroots of LINQ to SQL can actually be traced to something called ObjectSpaces dating back to 2001. Insimple terms, ObjectSpaces is a set of data access APIs that enable data to be treated as objects, r[r]
