EF ("entity framework") is the ORM. LINQ lets you write queries against any collection, such as a Dictionary or a List. So I write lots of "listOfFoo.Select(x => x.Name).ToArray()" style code with it, which compiles down efficiently.

These days "pipeline oriented programming" (which is what LINQ is) is seeping into many modern programming languages like Rust, although array programming languages are still (unreadable) kings at it.
