Linq uses a bunch of iterators functions that accept lambdas. C# allows them to capture the lambdas as an expression so it can convert the expression into SQL or whatever. it also has an SQL-like syntax you can use that is compiled into those iterators. the interface is generic, with builtin support for ienumerable types and SQL data sources.
