Answers to the Test Your Knowledge Questions

Chapter 1 - Hello, C#! Welcome, .NET Core!

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.csproj file, we type dotnet run.
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 Main and the preceding code is how it is declared. An optional string array for command-line arguments and a return type of int are recommended, but they are not required.
