.Net Framework Vs. .Net Core

The .NET Framework and .NET Core are two implementations of the .NET platform that serve different purposes and have distinct characteristics. Here are the key differences between .NET Framework and .NET Core:

Platform Support

  1. .NET Framework: It is designed for Windows and runs on the Windows operating system. It supports a wide range of Windows-based applications, including desktop applications, web applications, and server applications.
  2. .NET Core: It is cross-platform and supports Windows, macOS, and various Linux distributions. It is ideal for developing applications that need to run on multiple platforms, including cloud-based and containerized deployments.

Deployment Model

  1. .NET Framework: Applications built on the .NET Framework are typically deployed as standalone executables or installed using the traditional installer packages (MSI) on the target machine.
  2. .NET Core: Applications built on .NET Core can be deployed as self-contained executables that include the necessary runtime and libraries, making them highly portable. It also supports deployment through containerization technologies like Docker.

Performance and Scalability

  1. .NET Framework: It is a mature and feature-rich framework that offers a wide range of APIs and libraries. However, it is generally considered to have a larger footprint and may have slightly lower performance compared to .NET Core.
  2. .NET Core: It is designed to be lightweight and optimized for performance. It offers improved performance and scalability compared to the .NET Framework, especially in cloud-based and containerized environments.


  1. .NET Framework: It has been around for a longer time and has a large existing codebase and ecosystem of libraries and frameworks. However, it is limited to Windows platforms and may require modifications or additional effort to port applications to other platforms.
  2. .NET Core:It is a newer framework and has a smaller but rapidly growing ecosystem of libraries and frameworks. It is designed to be highly compatible with the .NET Framework, making it easier to port existing applications to .NET Core.

Future Development

  1. .NET Framework: Microsoft's focus on new features and enhancements is primarily directed towards .NET Core rather than the .NET Framework. However, the .NET Framework continues to be supported and maintained with bug fixes and security updates.
  2. .NET Core: It is the future of the .NET platform and is receiving continuous updates and improvements. Microsoft recommends using .NET Core for new development projects.

.Net 5

The .NET 5, and subsequent versions, aim to unify the different .NET variants and provide a single runtime and framework that can be used across multiple platforms. This unification effort is part of Microsoft's plan to simplify the .NET ecosystem and provide a consistent development experience.

With .NET 5 and later versions, developers will have the ability to target a wide range of platforms including Windows, Linux, macOS, iOS, Android, tvOS, watchOS, and even WebAssembly. This unified .NET runtime and framework will enable developers to write applications that can run seamlessly on these platforms, reducing the need for platform-specific code and simplifying the development process.

Moreover, .NET 5 introduces uniform runtime behaviors and developer experiences across platforms. This means that the same programming model, APIs, and language features will be available regardless of the target platform. This unification ensures that developers can use their existing knowledge and skills to build applications for different platforms without the need for significant relearning or adaptation.

The goal of .NET 5 and subsequent versions is to provide a cohesive and versatile development platform that offers broad platform support and a consistent programming model. This approach allows developers to write code once and deploy it on various platforms, increasing productivity and reducing development efforts.


By embracing .NET 5 and the unified .NET platform, developers can benefit from a more streamlined and efficient development experience, enabling them to create applications that reach a broader audience across different operating systems and devices.
