Top 5 Technical Interview Questions Asked to .Net Developer
- Why It’s Asked: Interviewers ask this to assess your understanding of the evolution of the .NET ecosystem and your knowledge of which version is more suitable for specific scenarios.
- Answer: Highlight that the .NET Framework is a mature, Windows-only platform ideal for building Windows applications, whereas .NET Core is a cross-platform, open-source framework that can run on Windows, macOS, and Linux. Mention that .NET Core is optimized for modern cloud-based applications and high-performance systems, and it is the foundation for .NET 5 and later versions.
- Why It’s Asked: Understanding garbage collection is crucial for memory management in .NET applications. This question tests your knowledge of how .NET handles memory.
- Answer: Explain that .NET uses a generational garbage collection system, consisting of three generations: Generation 0, 1, and 2. Generation 0 is for short-lived objects, Generation 1 is for objects that survive one garbage collection, and Generation 2 is for long-lived objects. The garbage collector works to free up memory by removing objects that are no longer referenced in the code.
- Why It’s Asked: Asynchronous programming is a key feature in modern .NET applications, especially for improving performance in I/O-bound operations. This question evaluates your understanding of asynchronous programming in .NET.
- Answer: Describe how the
asynckeyword is used to mark a method as asynchronous, allowing it to run asynchronously. Theawaitkeyword is used to pause the execution of the method until the awaited task completes. This allows other tasks to run in the meantime, improving the efficiency and responsiveness of the application.
- Why It’s Asked: Dependency injection is a crucial design pattern for creating modular and testable code in .NET. This question assesses your understanding of design patterns and your ability to implement them in .NET.
- Answer: Explain that dependency injection (DI) is a design pattern that allows developers to inject dependencies into a class, rather than having the class create them. In .NET, DI is typically implemented using an IoC (Inversion of Control) container, such as the built-in Microsoft.Extensions.DependencyInjection library. The container is responsible for managing the lifecycle of dependencies and injecting them where needed.
- Why It’s Asked: The MVC pattern is fundamental in building web applications with ASP.NET. This question tests your knowledge of web development and architectural patterns.
- Answer: Describe that the MVC pattern separates an application into three main components: the Model, which represents the data; the View, which is the UI or presentation layer; and the Controller, which handles user input and interaction. In ASP.NET, the Controller receives requests, interacts with the Model to retrieve or update data, and returns the View to be rendered.
