Top 25 .NET Core Basic Interview Questions and Answers for 2024
1. What is .NET Core Framework, and how does it work?
.NET Core is the successor of .NET, which is an open-source web development framework developed by Microsoft. It supports many applications, including web, mobile, desktop, cloud, IoT, and microservices. It provides a runtime environment and a set of libraries that developers use to build and run applications.

The striking features of .NET Core can be summarized as follows:
Cross-Platform: Runs on Windows, macOS, and Linux.
High Performance: Optimized for speed and scalability.
Modular Architecture: Allows adding only the necessary components.
Unified Programming Model: Supports various application types with a single framework.
Container Support: Works well with Docker and Kubernetes.
3. Which is the latest version of .NET Core?
Since .NET 6, .NET Framework and .NET Core have been unified into a single platform. The latest version of .NET Core is .NET 8, released in November 2023.
4. What is the difference between .NET Core and .NET Framework?
Cross-Platform: .NET Core is cross-platform, while .NET Framework is Windows-only.
Performance: Compared to .NET, .NET Core is optimized for performance and scalability.
Modularity: Unlike .NET, .NET Core is more modular, allowing developers to include only necessary components.
Development Model: Comparatively, .NET Core offers better support for modern development practices like microservices and containerization.
5. What is .NET Core used for?
.NET Core is used for building a wide range of applications, including:
- Web applications and services
- Mobile backends
- Desktop applications
- Cloud-based applications
- IoT applications
- Microservices
6. What is CTS in .NET Core?
CTS stands for Common Type System in .NET Core. It is a key component of the .NET framework that defines how types are declared, used, and managed in the runtime.
7. What are the advantages of .NET Core?
- Cross-Platform: It runs on multiple operating systems, such as Windows, Linux, Mac, etc., and can also be deployed on multiple platforms through containerization.
- High Performance: Every new release of .NET Core is optimized for performance, speed, and better scalability. .NET Core is also optimized for modern hardware and scalable applications.
- Open Source: All .NET Core documentation and source code is available for free download from Microsoft’s official website for .NET. In addition, one can also make contributions to the community. The strong community support facilitates continuous improvements.
- Modular and Lightweight: .NET Core offers the flexibility to be used by any database and infrastructure. It also allows adding only necessary components.
8. Explain the critical components of .NET Core.
As a modular platform, .NET Core’s components are divided into these layers:
- A .NET Runtime
- Collection of Framework libraries
- Collection of SDK tools and compilers
These layers can be stacked into the following components:
CLI tools: These help with development & deployment. CLI allows the building of console applications and class libraries.
Roslyn: It is a .NET compiler platform for C# and V. It is an open-source language compiler that allows dynamic compilation.?
CoreFX: It is a set of framework libraries that consists of a new Base Class library.
Core CLR: It allows runtime implementation on cross-platform. Core CLR is a JIT-based Command Language Runtime.
9. When should one not use .NET Core?
It is not advisable to use .NET Core during migration or in production, as you can encounter issues executing third-party libraries in .NET Core, even though they work in the .NET Framework. When designing loosely coupled and new large monolithic applications, one must avoid using .NET Core, which can lead to compatibility issues.
Avoid using .NET Core in applications requiring higher-level frameworks such as WCF, Entity Framework, and Windows Workflow Foundation.?
10. Are .NET and .NET Core the same?
.NET and .NET Core are not the same. Here are the differences:
| .NET | .NET Core |
|---|---|
| Windows only | Cross-platform (Windows, macOS, Linux) |
| Best suited for applications that need to leverage Windows-specific features. | Ideal for modern, scalable, and high-performance applications, including cloud-based and microservices architectures. |
| Supports WPF, Windows Forms, ASP.NET Web Forms, and other Windows-specific technologies | Does not support some older technologies like WPF and Windows Forms (though .NET 5 and later versions have integrated support for these). |
11. What is the difference between .NET Core and Mono?
| Parameters | .NET Core | Mono |
