When hiring a .NET full-stack developer, it's important to assess their knowledge of the Windows operating system. This includes their understanding of key differences between different versions of Windows and their knowledge of the underlying architecture and APIs that support the .NET framework. In this post, we'll explore some key questions you can use to test a candidate's Windows knowledge as part of your hiring process.
1. What's one of the biggest differences between Windows Server 2003 and Windows Server 2008? Or XP and Vista?
Answer: The Windows operating system has undergone significant changes over the years, with each new version introducing new features and capabilities. One of the biggest differences between Windows Server 2003 and Windows Server 2008 is the level of security and network infrastructure features. Windows Server 2008 introduced a number of security enhancements, such as improved network access protection and server core installations, as well as improvements in virtualization and storage. Windows XP and Vista also have differences in terms of the user interface, performance, and security features.
2. Name some classes under the System namespace in .NET?
Answer: The System namespace in .NET is the root namespace that contains many of the core classes and data types used by the .NET framework. Some of the classes under the System namespace include Object, String, Int32, DateTime, Array, and Exception.
3. What is Win32? How would I use it via .NET?
Answer: Win32 is the set of APIs (Application Programming Interfaces) for developing Windows applications. It provides a large number of functions for accessing the underlying functionality of the Windows operating system. In .NET, you can use the Win32 API by creating a managed wrapper around the Win32 functions using P/Invoke (Platform Invocation Services).
4. What compiles my code in .NET? What does it compile to?
Answer: The .NET compiler is responsible for compiling your code into an intermediate form known as Common Intermediate Language (CIL), which is executed by the .NET runtime. The .NET runtime is responsible for converting the CIL code into machine code that can be executed by the underlying hardware. This allows the same code to run on different platforms and devices that have the .NET runtime installed, without the need for recompilation.
In conclusion, these questions are a great starting point for testing a candidate's Windows knowledge as part of your hiring process for a .NET full-stack developer. By assessing their understanding of the Windows operating system and the underlying architecture and APIs that support the .NET framework, you can ensure that you're hiring someone who has the skills and knowledge needed to succeed in this role.
