Technical Questions and Answers for Microsoft Fullstack Engineer Interview at Advitha Tech Solutions

1. Can you explain the key differences between .NET Core and .NET Framework?

Answer:
.NET Core is a cross-platform, open-source framework that allows for more flexibility and better performance optimization across different operating systems. It supports microservices and cloud applications, making it ideal for modern, scalable web apps. .NET Framework, on the other hand, is Windows-only and is used for building desktop and large-scale enterprise applications. .NET Core offers faster deployment and better security enhancements, which are key in today’s fast-paced development environment.

2. How do you implement ASP.NET Web API in a project, and what are its benefits?

Answer:
I use ASP.NET Web API to create RESTful services that allow for communication between the front-end and back-end of an application. It supports a wide range of content types, including JSON and XML, and is ideal for building HTTP-based services. The main benefits of ASP.NET Web API are its scalability, ease of use with front-end frameworks like React, and the ability to create lightweight, stateless services.

3. What role does LINQ play in application development, and how do you use it?

Answer:
LINQ (Language-Integrated Query) simplifies the querying of data from various sources, like databases or in-memory collections, by allowing queries directly in the code using C#. This reduces the complexity and improves the readability of code. I use LINQ to perform complex data manipulation operations in a more efficient and concise way, improving both performance and maintainability.

4. How would you approach designing and deploying Azure Functions in a full-stack application?

Answer:
Azure Functions provide serverless computing, which allows me to deploy and scale functions automatically without managing infrastructure. In a full-stack application, I would use Azure Functions to handle event-driven tasks like processing HTTP requests, integrating with external systems, or responding to events from Service Bus. It helps reduce server load and speeds up processes. I also ensure the function’s security using API Management and deploy them using Azure DevOps for continuous integration.

5. How do you manage state and performance optimization when using React for front-end development?

Answer:
For state management in React, I typically use Redux or Context API to centralize the application’s state. This allows for predictable state transitions and enhances the overall performance of the application. To optimize performance, I focus on memoization using React.memo and useMemo hooks to prevent unnecessary re-renders, lazy loading components to reduce initial load time, and optimizing bundle size by splitting code where needed.

6. Can you explain the use of Azure Service Bus in microservices architecture?

Answer:
Azure Service Bus is a message broker that helps in decoupling microservices, ensuring that different parts of an application communicate effectively without being directly dependent on each other. I use Azure Service Bus for message queuing in distributed applications to ensure that messages are properly handled, retried in case of failures, and delivered in a scalable and resilient manner. It also helps in asynchronous processing and workload distribution across microservices.

7. How do you secure web applications in ASP.NET using authentication and authorization?

Answer:
I implement ASP.NET Core Identity for user management and authentication, using OAuth or OpenID Connect to integrate with external providers like Azure Active Directory or Google. For authorization, I configure Role-based Access Control (RBAC) or Claims-based Authentication, ensuring that each user has the appropriate access to different parts of the application. I also use HTTPS, secure tokens (JWT), and data encryption to protect sensitive data.
