A Quick Comparison Of .NET Framework vs .NET Core

It has been almost two decades since Microsoft introduced its .NET offering at the Forum 2000 event. However, there has much confusion about what .NET exactly is — an underlying development framework or an ideal choice of language for app development. .NET then evolved beyond the Windows ecosystem, bringing Microsoft’s tools and technologies to platforms like Android, iOS and now Linux.

However, this growth further resulted in a new set of questions: Which .NET is ideal to leverage for Dot NET website development — .NET framework or .NET Core? With a variety of libraries and runtimes, the choice is undoubtedly difficult. Hence, we have come up with a brief comparison between .NET Framework and .NET Core to help you make a right decision. Let’s get started.

.NET Framework: The .NET Framework provides support for developing Windows and web applications. It allows developers to use Windows Forms, WPF, and Universal Windows Platform (UWP) for building Windows-based apps and ASP.NET MVC for developing web applications.

.NET Core: It is a new open source, the cross-platform framework used for writing apps on Windows, Mac, and Linux systems. However, it only supports Universal Windows Platform (UWP) and ASP.NET Core. However, you can use UWP to create Windows and mobile apps, and ASP.NET Core to write browser-based web apps.

Presented here are some differences based on different parameters:

#Open Source Platform:

.NET Framework: Not an open source platform

.NET Core: An open source platform


.NET Framework: It is not cross-platform and only runs on Windows operating system

.NET Core: It is cross-platform, hence, runs on Windows, Mac and Linux operating systems

#Web App Development:

.NET Framework: Leveraged for developing a desktop Windows apps working with ASP.NET

.NET Core: Used for producing apps that can work across a range of platforms including ASP.NET Core for cross-platform web apps


.NET Framework: Distributed with Windows

.NET Core: Distributed with apps


.NET Framework: It provides High-performance and scalable system without UI

.NET Core: It is much faster


.NET Framework: It is a stable framework to build and deploy applications immediately

.NET Core: It is not entirely matured even though it has been around since 2001

When To Use .NET Framework:
-Lack .NET Core capabilities and investment/time for getting required skills on board
-Need a stable environment for building and deploying your app
-Need to initiate the .NET app development project quickly
-Are working on a project that entails extending the functionality of an existing app
-Have a dedicated team of .NET experts with a proven record of creating production-ready software
-Find .NET Core and its continuous upgrades challenging to manage
-Are developing Windows client apps for desktops, laptops with WinForms and WPF

When To Use .NET Core:
-Want to build apps for Windows, Linux and Mac operating systems
-Have ability and time for learning new skills 
-Are open to many changes and learning new things, considering .NET Core is not an entirely matured platform
-Favor open source

Closing Remarks:
Hopefully, the above .NET Framework versus .NET Core comparison will steer you in the direction of making a correct choice. In case of any queries or questions, do feel free to write to us in the comment section below.
