The Evolution of LINQ and Its Impact on the Design of C#
Anson Horton (via Lambda):
Several years ago, Anders Hejlsberg (chief designer of C#) and Peter Golde thought of extending C# to better integrate data querying. Peter, who was the C# compiler development lead at the time, was investigating the possibility of making the C# compiler extensible, specifically to support add-ins that could verify the syntax of domain-specific languages like SQL. Anders, on the other hand, was conceiving a deeper, more specific level of integration. He was thinking about a set of “sequence operators” that would operate on any collection that implemented IEnumerable, as well as remote queries for types that implemented IQueryable.
