Summary

C# 2008 provides a number of very interesting features that bring C# into the family of functional

languages. This chapter walked you through each of the core updates, beginning with the notion of

implicitly typed local variables. While the vast majority of your local variables will not need to be

declared with the var keyword, as you will see in the next chapter doing so can greatly simplify your

interactions with the LINQ family of technologies.

This chapter also described the role of automatic properties, partial methods, extension

methods (which allow you to add new functionality to a compiled type), and the syntax of object

initialization (which can be used to assign property values at the time of construction).

The chapter wrapped up by examining the use of anonymous types. This language feature

allows you to define the “shape” of a type rather than its functionality. This can be very helpful when

you need to model a type for limited usage within a program, given that a majority of the workload

is offloaded to the compiler.
