1. What inspired you to become a .NET full-stack developer and what experience have you had with the technology?
Answer: I have always been passionate about technology and finding new and innovative ways to solve complex problems. I have been working as a .NET full-stack developer for the past 5 years and have gained extensive experience in building scalable and robust web applications using the .NET framework.
2. What are the key differences between .NET Core and .NET Framework, and when would you use one over the other?
Answer: .NET Core is a modern, open-source, and cross-platform version of the .NET Framework, while .NET Framework is a closed-source, Windows-only version. I would use .NET Core for building new applications that need to run on multiple platforms or need to take advantage of the latest features and improvements .NET. In contrast, I would use .NET Framework for legacy applications that are already running on Windows and don't need the features provided by .NET Core.
3. Can you explain the Model-View-Controller (MVC) pattern and how it's used in .NET applications?
Answer: The Model-View-Controller (MVC) pattern is a design pattern used for building web applications. It separates the application into three main components: the model, which represents the data and business logic of the application; the view, which displays the data to the user; and the controller, which handles user input and updates the model and view accordingly. In .NET applications, the MVC pattern is commonly used to build scalable and maintainable web applications using the ASP.NET MVC framework.
4. How do you handle version control in your .NET projects and what tools have you used?
Answer: I usually use Git for version control in my .NET projects. I am familiar with branching and merging. I follow best practices such as creating a separate branch for each feature, regularly committing and pushing changes, and creating pull requests for code review. I have also used other version control tools such as SVN in the past.
5. Can you walk us through how you would approach debugging a complex issue in a .NET application?
Answer: When debugging a complex issue in a .NET application, I would follow these steps:
Reproduce the issue: I would try to reproduce the issue in a development environment to understand better what is happening.
Examine logs and error messages: I would look at any logs or error messages generated by the application to gain more insight into the issue.
Use debugging tools: I would use tools such as the Visual Studio debugger or the .NET Core CLI debugger to step through the code and inspect variables and objects.
Try different solutions: I would try different solutions and approaches, such as adding logging or instrumentation, until I find the root cause of the issue.
Test and verify the fix: Finally, I would test and verify the fix to make sure that the issue has been resolved and that the solution does not introduce any new problems.
6. How would you deploy a .NET web application to Azure?
Answer: There are a number of ways to deploy a .NET web application to Azure, including using Azure App Service, which provides a platform for deploying web applications. Another option is to use Azure Virtual Machines, which allows you to deploy and run virtual machines in the cloud. Additionally, you can use Azure Container Instances or Azure Kubernetes Service to deploy .NET applications in containers.
7. How would you secure a .NET web application running on Azure?
Answer: Securing a .NET web application running on Azure requires a multi-layered approach. You would need to secure the application itself, as well as the underlying infrastructure, including the network and storage components. Some of the key security measures you might implement include using secure authentication and authorization mechanisms, using encryption for sensitive data, and using firewalls and network security groups to control network access.
