Summary

In this chapter, we covered the most important new features of Visual Basic 9.0, dividing them into four main sections. The first was about nullable types, which have been part of C# since version 2.0. The second section discussed features matching C# 3.0: local type inference, extension methods, object initialization expressions, anonymous types, query expressions, lambda expressions, and closures. The third section covered features present only in Visual Basic 9.0: XML literals, late binding over XML, and relaxed delegates. Finally, the last section was dedicated to features present in C# 3.0 but not in Visual Basic 9.0: the yield keyword and anonymous methods. In the next chapter, you will learn about some of the fundamentals of LINQ syntax.
