Difference Between .NET Framework and .NET Core

.NET Core is the new open-source and cross-platform framework to build applications for all operating system including Windows, Mac, and Linux.

The .NET Framework supports Windows and Web applications. ASP.NET MVC is used to build Web applications in .NET Framework. By using .NET Framework you can utilize Windows Forms, UWP, and WPF to develop Windows desktop applications and server-based applications in .NET Framework.


 .NET Core is the new cross-platform and open-source .NET framework to develop applications for all major operating system including Mac, Linux, and Windows. .NET Core supports UWP and ASP.NET Core only. ASP.NET Core is used to build browser-based web applications and currently, it does not support a desktop application with the user interface. Programmers can develop applications and libraries in C#, VB.NET, and F# in both run times.

Difference between .NET Framework and .NET Core
Features.NET Framework.NET Core
Open Source.NET Framework was releases as a licensed and proprietary software framework..NET Core as an open source software framework. Hence, both enterprise and individual developers can build apps with .NET Core without paying any licensing fees.
Cross-Platform:.NET Framework enabled developers to build applications for a single platform — Windows..NET Core is cross-platform, and supports three distinct operating systems — Windows, OS X, and Linux. The compatibility makes it easier for developers to build cross-platform applications, and port their existing applications from one platform to another.
InstallationThe .NET Framework needs to be installed as a single package and run-time environment for Windows..NET Core is cross-platform, and needs to be packaged and installed independent of the underlying operating system. The developers are required to compile Nuget packages included in .NET Core. Also, they can compile the Nuget packages directly into the application or place them in a folder inside the application.
Modular Collection of LibrariesBoth .NET Framework and .NET Core allows developers to take advantage of robust class libraries..NET Core uses a redesigned common language runtime called CoreCLR, and features a modular collection of libraries called CoreFX. Hence, the developers have option to pick and use only the libraries required by each application, and enhance the application’s performance by removing unnecessary libraries.
Application ModelsThe application model of .NET Framework includes Windows Forms, ASP.NET, and Windows Presentation Foundation (WPF)..NET Core includes ASP.NET Core and Windows Universal Apps.
Standard LibraryAs a formal specification of .NET APIs, the .NET Standard Library meets the requirements of varying runtimes and maintains uniformity in the .NET ecosystem.Each version of .NET Framework uses a specific version of .NET Standard Library..NET Framework 4.6 implemented the .NET Standard Library 1.3, whereas .NET Framework 4.6 2 implemented the .NET Standard Library 1.5.But .NET Core implements version 1.6 of the .NET Standard Library.
ASP.NETWhile using web applications with .NET Framework, the developers have option to use a robust web application framework like ASP.NET..NET Core comes with a redesigned version of ASP.NET. The developers can now use ASP.NET Core to build both web and cloud applications. In addition to being open source, ASP.NET Core is also available on three distinct platforms — Windows, OS X, and Linux
Deployment OptionsWhile using .NET Framework, developers have to deploy web applications only on Internet Information Server.ASP.NET Core can be hosted in a number of ways. The developers can deploy the ASP.NET Core applications directly in the cloud or self-host the application by creating their own hosting process.
Cloud Ready ConfigurationThe developers can use ASP.NET to build a variety of cloud-based applications rapidly. Unlike .NET Framework, .NET Core is designed with features to simplify development and deployment of cloud-based application. Also, they can publish the applications directly to the cloud by availing the cloud-ready configuration included in ASP.NET Core.
Mobile App Development.NET Framework does not include any robust framework or tools to simplify mobile app development..NET Core compatible with Xamarin through the .NET Standard Library. Hence, developers can take advantage of Xamarin to write cross-platform mobile apps in C# with a shared code base and same set of APIs. They can further use the tools provided by Xamarin to customize the mobile app for individual mobile platforms like iOS, Android and Windows Phone.
Microservices--Unlike .NET Framework, .NET Core makes it easier for developers to build microservice oriented systems rapidly. As such systems include a number of independent and dynamic microservices, the developers have to focus on individual microservices. .NET Core enables programmers to develop custom microservices by using varying programming languages, technologies and frameworks. Also, the developers can build a robust system by combining multiple microservices seamlessly.
Performance and ScalabilityLess Scalable .NET Core is more effective than .NET Framework to enhance the performance and scalability of applications. It enables developers to enhance the performance of applications drastically without deploying additional hardware or infrastructure. Also, it allows developers to build, test and deploy applications directly in the cloud. Hence, the developers can switch to .NET Core to enhance the performance and scalability of their applications without putting extra time and effort.
Compatibility--.NET Core does not support all the features and functionalities provided by the latest version of .NET Framework. But it can be used as a subset of the .NET Framework. Also, .NET Core is still compatible with .NET Framework through the .NET Standard Library. Hence, the developers can still run the applications developed with .NET Framework after upgrading to .NET Core.

.NET Core is the updated and redesigned version of .NET Framework. The .Net developers can upgrade to .NET Core to build a variety of applications by targeting multiple devices and platforms. Also, they can take advantage of the new features and enhancements included in .NET Core to build, test, and deploy the applications efficiently and rapidly.
