Understanding Difference Between .NET Core Vs .NET Framework Vs
.NET Standard

When it comes to developing software applications, there are different frameworks that developers can use. Two of the most popular frameworks are .NET Core and .NET Framework. While both share some similarities, there are also some key differences between the two. In this article, we will explore the .NET Core framework and compare it to the .NET Framework, as well as discuss the .NET Standard.



.NET Core is a cross-platform, open-source, and modular .NET platform for creating modern web apps, microservices, libraries, and console applications. .NET Core is composed of a set of NuGet packages that are distributed as part of the ASP.NET Core web framework. It includes the runtime, framework, compiler, and other tools necessary to create and run applications.

.NET Framework is a Windows-only, closed-source platform for creating traditional desktop apps, web apps, and services. It includes the runtime, framework libraries, compilers, and other tools necessary to create and run applications.

.NET Standard
is a set of APIs that all .NET platforms must implement in order to be compatible with each other. This allows developers to create code that can run on any .NET platform without modification.

The .NET Framework is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library named Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages.

The key difference between .net core and .net framework is that the .net core is open source whereas the .net framework is not. The other main difference between .net core and .net framework is that net core can run on multiple platforms like Windows, Linux, macOS whereas net framework can only run on Windows platform.

Also, net core supports side-by-side installation meaning multiple versions of same assembly can be installed in same machine at same time which is not possible with net framework installed models.

Microsoft started development on the .NET Framework in late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2000, the first beta versions of .NET 1.0 were released. The first version of .NET Framework was released on 13 February 2002, bringing managed code to Windows NT 4.0, 98 and ME operating systems. Version 1.1 arrived on 30

.NET Standard is a set of specifications that define how .NET libraries should work. It is not a new .NET runtime or a new way to write code. Rather, it is a standardized way of writing code that can run on any .NET runtime.

This means that code written for .NET Standard can be used on any platform that supports .NET Standard, including .NET Framework, .NET Core, Xamarin, and Mono.

NET Standard was created to solve the problem of different .NET platforms not being compatible with each other. For example, a library written for .NET Framework might not work on .NET Core because they use different APIs. By using NET Standard, developers can create libraries that work on all .NET platforms without having to rewrite their code for each platform.

In order to use NET Standard, developers need to target their code to a specific version of NET Standard. The current version is 2.0, which was released in 2017. This version includes many features that were not available in previous versions, such as support for ASP.NET Core and Entity Framework Core.

Comparison

.NET Core is a cross-platform, open-source, and modular .NET platform that can be used to build device, cloud, and IoT applications.

• Cross-platform
• Open-source
• Modular design allowing for customizability
• Can be used to build device, cloud, and IoT applications

.NET Framework is a Windows-only, closed-source .NET platform for building desktop, web, and server applications.

• Windows-only
• Closed-source
• Desktop, web, and server applications

.NET Standard is a set of specifications that defines the core functionality of .NET platforms. It is implemented by both .NET Core and .NET Framework.

At its simplest, you can think of .NET Standard as an improved version of Portable Class Libraries (PCLs) with better support for platform diversity.

Like PCLs before it, .NET Standard provides a way for libraries to be compiled once and used on multiple target platforms–including .NET Framework,. NET Core,. Xamarin iOS/Android,. Universal Windows Platform (UWP), Tizen,. tvOS/. macOS/. NET NanoFramework…. In other words: If it runs on .Net–be it full framework or any other flavor– chances are high that your library will run just fine when targeting the right version.
