ASP.NET MVC: Despite being more efficient than Web Forms, it isn’t as lean or fast as ASP.NET Core.
ASP.NET Core: Offers improved performance through efficient middleware pipeline, better memory management, and lighter-weight framework design. It achieves better throughput due to Kestrel, a high-performance, cross-platform web server. The modular nature allows developers to include only necessary components, reducing overhead.

4. Middleware

ASP.NET MVC: Utilizes HTTP Modules and Handlers for request processing.
ASP.NET Core: Employs a single, unified middleware pipeline which simplifies the request processing model, making it easier to understand and customize.

5. Modularity & Startup.cs Configuration

ASP.NET MVC: Uses a Global.asax file to configure application Startup.
ASP.NET Core: Features a more organized Startup.cs file that centralizes configuration, dependency injection, and middleware registration. This modular approach enhances maintainability and flexibility.

6. Dependency Injection

ASP.NET MVC: Offers basic dependency injection (DI) support.
ASP.NET Core: Integrates a robust DI container into the framework, making it easy to register services and manage dependencies across the application lifecycle.

7. Security

ASP.NET MVC: Provides comprehensive security features but requires additional setup for advanced scenarios.
ASP.NET Core: Incorporates advanced security practices out of the box, including JWT tokens, OAuth, and OpenId connect support, simplifying the process of securing applications.

8. Entity Framework Core Support

ASP.NET MVC: Works with both Entity Framework 6 and CodeFirst Migrations.
ASP.NET Core: Primarily uses Entity Framework Core, which offers better performance, cross-platform support, and integrated dependency injection.

9. Build Process

ASP.NET MVC: Uses MSBuild for project lifecycle management.
ASP.NET Core: Employs a modern build process based on the .NET CLI (Command Line Interface), providing more control and flexibility over the build process.

10. Package Management

ASP.NET MVC: Relies on NuGet packages for third-party components.
ASP.NET Core: While continuing to use NuGet, ASP.NET Core introduces a more streamlined and efficient package reference system.

11. Compatibility

ASP.NET MVC: Compatible only with the .NET Framework.
ASP.NET Core: Cross-platform, compatible with both .NET Framework and .NET Core, ensuring greater future-proofing and expandability.

Conclusion

In transitioning from ASP.NET MVC to ASP.NET Core, developers gain access to a rich set of features and improvements that enhance application performance, security, and scalability while achieving cross-platform functionality.

Top 10 Interview Questions & Answers on Differences between ASP.NET MVC and ASP.NET Core

Top 10 Questions and Answers about Differences Between ASP.NET MVC and ASP.NET Core

Answer: ASP.NET MVC (Model-View-Controller) is a framework developed by Microsoft for building web applications with a clean separation of concerns. It was introduced in 2009 and allows developers to create dynamic web applications that utilize the full power of the .NET Framework. It adheres to the MVC architectural pattern which helps in structuring an application in three layers – Model (business logic and data access), View (UI), and Controller (handles user interaction).

2. What is ASP.NET Core?

Answer: ASP.NET Core is an open-source cross-platform successor to ASP.NET MVC and Web API. It was released in 2016. ASP.NET Core allows developers to create modern cloud-based, internet-connected apps that run on Windows, Mac, and Linux. It is designed to be modular and highly performant, and it supports multiple frameworks including MVC, Razor Pages, Blazor, and gRPC services.

3. Which is better: ASP.NET MVC or ASP.NET Core?

Answer: The choice between ASP.NET MVC and ASP.NET Core depends on your project requirements and environment. ASP.NET MVC is stable and widely used, making it a safer bet for production applications. ASP.NET Core, however, offers significant advantages such as cross-platform support, better performance, and modular architecture, making it a more versatile choice for modern web applications.

4. What are the key differences in architecture between ASP.NET MVC and ASP.NET Core?

Answer:

Modularity: ASP.NET Core is modular and includes only the necessary components, whereas ASP.NET MVC is more tightly integrated with the .NET Framework.
Performance: ASP.NET Core is generally more performant and resource-efficient, which is crucial for high-scalability applications.
Cross-Platform: ASP.NET Core runs on Windows, macOS, and Linux, whereas ASP.NET MVC runs only on Windows.
Configuration: ASP.NET Core uses JSON-based configuration files, which are more flexible and easier to manage compared to XML in ASP.NET MVC.

5. Are ASP.NET MVC and ASP.NET Core compatible?

Answer: ASP.NET MVC and ASP.NET Core are not directly compatible. ASP.NET Core is a rewrite of the ASP.NET framework that introduces significant changes in the way applications are structured and run. While ASP.NET MVC is specifically designed for the full .NET Framework, ASP.NET Core targets the .NET Core framework (and now .NET 5+), which is cross-platform. Existing ASP.NET MVC applications cannot be seamlessly upgraded to ASP.NET Core, but they can be migrated with efforts and refactoring.

6. How does routing work in ASP.NET MVC and ASP.NET Core?

Answer: Routing in both frameworks directs incoming HTTP requests to specific controller actions (in the case of ASP.NET MVC) or endpoints (in the case of ASP.NET Core).

ASP.NET MVC: Uses a conventional-based routing system where URL patterns are defined in the RouteConfig.cs file and actions are mapped based on controller name and action method name.
ASP.NET Core: Uses Attribute Routing, where routes are defined directly above controller actions. It’s more flexible and provides a better way to handle complex routing scenarios.

7. What are the data access techniques in ASP.NET MVC and ASP.NET Core?

Answer: Both frameworks support data access techniques like Entity Framework, Dapper, NHibernate, etc., but ASP.NET Core offers better integration with modern tools and libraries:

Entity Framework Core: Specifically designed for ASP.NET Core, this ORM tool provides a more modular and lightweight version of Entity Framework that supports multiple databases and is easier to extend.
Dapper: An object-relational mapper (ORM) for .NET which offers greater control and performance compared to full ORM solutions like Entity Framework.

8. How does ASP.NET MVC and ASP.NET Core handle authentication and authorization?

Answer: Both frameworks provide robust mechanisms for handling authentication and authorization, though ASP.NET Core offers a more streamlined and flexible approach.

ASP.NET MVC: Primarily uses cookie-based authentication and authorization with roles and claims.
ASP.NET Core: Uses the ASP.NET Core Identity framework which provides more flexibility with authentication providers and supports external login providers, cookie-based authentication, and roles/claims-based authorization.

9. Can you compare the startup configuration in ASP.NET MVC and ASP.NET Core?

Answer: Startup configuration is a key difference between the two:

ASP.NET MVC: Configuration is done in the Global.asax.cs file, where routing information and various application-level settings are defined.
ASP.NET Core: Configuration is centralized in the Program.cs and Startup.cs files. It leverages middleware to configure HTTP request pipeline and services, making it more modular and easier to manage.

10. How do ASP.NET MVC and ASP.NET Core handle static files?

Answer: Managing static files in both frameworks differs in terms of flexibility and ease of use.

ASP.NET MVC: Requires enabling static file serving through the Web.config file or by using the StaticFileHandler.
ASP.NET Core: Easily configures static files with the app.UseStaticFiles() middleware in the Startup.cs file, providing a straightforward and efficient method to serve static assets. Additionally, it supports options like setting cache headers, file types, etc.
