Parallel Programming w/ Task Parallel Library
In this episode we are going to take a look at how we can simplify parallel programming by using the Task Parallel Library which is part of .Net 4.0

We will take a look at how to move your code away from for and foreach and towards Parallel.For and Parallel.Foreach. These new methods allow you to parallelize your loops w/ little effort, but with large gains.

Exploring Operator Overloading in C#
In this episode we are going to take a look at how create overloaded operators for your objects.

perator overloading permits user-defined operator implementations to be specified for operations where one or both of the operands are of a user-defined class or struct type. When creating your own operators there are many different operators which can be overloaded.

+, -, *, /, %, &, |, <<, >> All C# binary operators can be overloaded
+, -, !, ~, ++, –, true, false All C# unary operators can be overloaded
==, !=, <, >, <= , >= All relational operators can be overloaded, but only as pairs.

Introduction to AutoMapper
In this episode we will take a look at how we can simplify our entity mapping by using AutoMapper.

AutoMapper uses a fluent configuration API to define an object-object mapping strategy. AutoMapper uses a convention-based matching algorithm to match up source to destination values. Currently, AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer.
