In this chapter, we have learned about the new features introduced in C# 7.0, along with the release of Visual Studio 2017. We have also demonstrated each of them with examples/code.

At a glance, we have learned about local or nested functions, literal improvements, the new digit separators, pattern matching, ref returns and locals, changes in tuples, changes to the throw expression, and expression-bodied members. We also learned about the new changes to the out variables, deconstruction syntax, and the uses of generalized async return types.

As we have become familiar with the features of C# 7.0, let's move on to the next chapter, where we will learn about building applications for Windows using Windows Presentation Foundation. We will also learn how to design a XAML UI, do data bindings, and much more.
