Chapter 3. The .NET Languages
Unlocking the productivity promises of the Visual Studio IDE is at the heart of this book. The IDE, of course, also ships from Microsoft in concert with new versions of the .NET languages and Framework. You need to have a solid grasp of programming the Visual Basic or C# language using the .NET Framework to take advantage of everything Visual Studio has to offer. Of course, you may also need to know many other things such as XAML, Hypertext Markup Language (HTML), Cascading Style Sheets (CSS), TypeScript, JavaScript (and related frameworks), C++, F#, and LightSwitch. Today’s developer likely does not code in a single language syntax. However, VB and C# are still at the core of most Visual Studio development.
In this chapter, we set aside the IDE (for the most part) and focus on the foundations of .NET programming in C# and Visual Basic. We start by highlighting new features of the languages for those who are already familiar with C# and VB. We then include a language primer as a review of some basic .NET programming tasks. We then cover some more in-depth programming features, enhancements to C# 6.0 and VB 14, and language-related IDE enhancements. The chapter concludes with an overview and map of the .NET Framework class library.
