This post is yet another technology placeholder.
I found the other day my PDC 05 notes and specifically Linq which I thought I better check in on again. I came across Wes Dyer’s blog , which is sensational but my head hurts. Instantly like the guy as he has a good interest in board games.
The PDC expression back then was New UP (as in new;ing up something)
An overview of the main feature lambda expression is well detailed here
My notes (incomplete – I will need to add reference to MSDN later):
Lambda expression – provide a more concise, functional syntax for writing anonymous methods
Identifiable by => and the keyword Func
Lambda expression tree – expression lambda expressions as a graph
extension methods – add methods to types that already exist (e.g. IEnumerable)
Object initializers – typical embedded .net objects
var keyword – same as type initializer
anonymous types – create new type based on predefined type (you dont need to specify type as it is inferred by result)
A good article on Lambda expressions, and the progression from .net 2.0, can be found here
