Module 1: From C# 2.0 to C# 3.0
This module explains how to apply C# 3.0 language features in real applications, and provides the motivation for each feature, categorizing them into four distinct groups: Developer productivity features, Extensibility features, Functional programming features and LINQ support features.

Lessons
• Developer Productivity Features – Implicit typing, Object and collection initializes, Automatic properties, Anonymous types.
• Extensibility Features – Extension methods, Partial methods.
• Functional Programming Features – Lambda expressions, Expression trees.
• LINQ Support Features – An overview of language query operators.

Lab : Extension Methods and IEnumerable
• ForEach extension method for IEnumerable.
• MaxElement extension method for IEnumerable.

Lab : Extension Methods and Anonymous Types
• Extension method for turning anonymous types into tuples.

After completing this module, students will be able to:
• Extend existing types using extension methods.
• Use lambda expressions and expression trees for simple functions.
• Initialize collections and objects and use automatic properties and anonymous types to facilitate productivity.
