This appendix has the answers to the questions in the Test Your Knowledge section at the end of each chapter.
- Why can a programmer use different languages, for example C# and F#, to write applications that run on .NETCore?
- Multiple languages are supported on .NET Core because each one has a compiler that translates the source code into IL (intermediate language) code. This IL code is then compiled to native CPU instructions at runtime by the CLR.
- What do you type at the prompt to build and execute C# source code?
- Using .NET Core CLI in a folder with a
ProjectName.csprojfile, we typedotnet run.
- Using .NET Core CLI in a folder with a
- What is the Visual C# developer settings keyboard shortcut to save, compile, and run an application without attaching the debugger?
- Ctrl + F5.
- What is the Visual Studio Code keyboard shortcut to view the Integrated Terminal?
- Ctrl + ` (back tick).
- Is Visual Studio 2017 better then Visual Studio Code?
- No. Each is optimized for different tasks. Visual Studio 2017 is large, heavy-weight, and can create applications with graphical user interfaces, for example WPF, UWP, and Xamarin mobile apps, but is only available on Windows. Visual Studio Code is smaller, lighter-weight, command line and code-focused, and available cross-platform.
- Is .NET Core better than .NET Framework?
- It depends on what you need. .NET Core is a slimmed down, cross-platform version of the more full-featured, mature .NET Framework.
- How is .NET Native different from .NET Core?
- .NET Native is an ahead-of-time compiler that can produce native code assemblies that have better performance and reduced memory footprint, and it has its .NET assemblies statically linked, which removes its dependency on CoreCLR.
- What is .NET Standard and why is it important?
- .NET Standard is an API that future versions of .NET Framework, .NET Core, and Xamarin will implement to provide a single, standard API that developers can learn and target.
- What is the difference between Git and GitHub?
- Git is a source code management platform. GitHub is a popular web service that implements Git.
- What is the name of the entry point method of a .NET console application and how should it be declared?
public static void Main() // minimum public static int Main(string[] args) // recommended- Its name is
Mainand the preceding code is how it is declared. An optionalstringarray for command-line arguments and a return type ofintare recommended, but they are not required.
- Its name is
