My career started as a hard-core functional-paradigm developer (LISP), and now I'm a hard-care .net/C# developer. Of course I'm enamored with LINQ. However, I also believe in (1) using the right tool for the job and (2) preserving the KISS principle: of the 60+ engineers I work with, perhaps only…

.Select(y=>y.Field<decimal>("decimalfield"));
