Common .NET Core Interview Questions

  1. What is .NET Core, and how does it differ from the traditional .NET Framework?
    • .NET Core is an open-source, cross-platform framework for building modern applications. It differs from the traditional .NET Framework as it’s cross-platform and modular, allowing developers to build and run applications on Windows, macOS, and Linux.
  2. What are the key features of .NET Core?
    • Key features of .NET Core include cross-platform support, high performance, open-source nature, and modularity. It’s designed for modern, cloud-native applications.
  3. What is the significance of cross-platform development in .NET Core?
    • Cross-platform development means you can write code once and run it on different operating systems, which is essential in today’s diverse computing environments.
  4. Explain the process of creating a simple .NET Core application.
    • Create a new project using the dotnet new command, write your code, build it with dotnet build, and run it with dotnet run.
  5. What is the role of the dotnet CLI in .NET Core development?
    • The dotnet Command-Line Interface is used for project creation, building, running, testing, and publishing .NET Core applications.
  6. Describe the structure of a typical .NET Core project.
    • A typical .NET Core project consists of source code files, project files (e.g., .csproj), configuration files, and a folder structure. It follows a modular structure with dependencies specified in the project file.
  7. What are NuGet packages, and how are they used in .NET Core projects?
    • NuGet packages are libraries and tools that can be added to .NET Core projects. They are used for adding third-party dependencies and are managed through the NuGet package manager.
  8. How does dependency injection work in .NET Core, and why is it important?
    • Dependency injection is a technique in which dependencies are provided to a class rather than created within it. In .NET Core, it’s built into the framework and is crucial for decoupling components, improving testability, and maintaining modularity.
  9. What is ASP.NET Core, and how does it relate to .NET Core?
    • ASP.NET Core is a web framework built on top of .NET Core. It provides tools and libraries for building web applications, APIs, and more, and is designed to be cross-platform.
  10. Compare and contrast ASP.NET Core with ASP.NET MVC.
    • ASP.NET Core is a more modern and cross-platform framework that encompasses web development, whereas ASP.NET MVC is a part of the traditional .NET Framework and is primarily for web development on Windows.

  1. Its like you learn my mind! You seem to know so much about this, like you
    wrote the guide in it or something. I think that you just could do with a few p.c.
    to power the message home a bit, however instead of that, that is excellent
    blog. A fantastic read. I’ll definitely be back.
