Two more questions from the floor at TechEd.
Perhaps the most frequent question at TechEd is “What are the new features of C# 3.0?” Here is the short list:
• Implicitly typed local variables
• Extension methods
• Lambda expressions
• Object and collection initializers
• Anonymous types
• Implicitly typed arrays
• Query expressions
• Expression trees

Also got a question about what a Delegate was. Here is the definition from the documentation. A delegate is a type that references a method. Once a delegate is assigned a method, it behaves exactly like that method. The delegate method can be invoked like any other method, with parameters and a return value.
