In this post, we will describe the run-time and its comparison and make it simple for you to choose the one that will help you create the most excellent program.

What is .NET Core?

Microsoft and the .NET community on GitHub support a general-purpose programming environment called .NET Core. In addition, a cross-platform framework called .NET Core may be used with Windows, macOS, and Linux. As a bonus, it is open-source and welcomes developer community contributions. Since  .NET Core is a whole new framework, it is modular, light, quick, and cross-platform.


The non-profit open-source  .NET Foundation manages  .NET Core, a program created by Microsoft. Even non-Windows operating systems like macOS and Linux support its use. This is comparable to what other all-purpose frameworks like NodeJS provide.

Pros of Using .NET Core

  • As .NET Core is modular, you can include only the libraries and components your application needs, significantly reducing its footprint.

  • It is an open-source platform that works with many different operating systems.

  • .NET Core apps are simpler to deploy than  .NET Framework apps.

  • Because it supports side-by-side versioning, you can run several versions of  .NET Core on the same computer without any issues.

What is .NET Framework?

The .NET Framework is a software framework developed by Microsoft that predominantly operates on Microsoft Windows. Software applications can be created and executed with .NET Framework. The performance of .NET Framework is excellent. However, even though the source code is easily accessible, the developer community cannot actively contribute to it.


The .NET framework offers an execution environment using Common Language Runtime, which controls memory and thread utilization. The CLR also serves as a just-in-time compiler, transforming intermediate code into machine code before it is executed.


Microsoft's latest version of the Framework as a proprietary product was .NET 4.8. Since then, no new features have been added; only reliability and bug patches have been made available.

Pros of Using .NET Framework


  • The Integrated Development Environment (IDE) for Visual Studio includes the .NET Framework. With the help of this tool, programmers can easily construct apps.


  • Since its release, the .NET Framework has amassed a sizable community but it wasn't until Microsoft declared it open-source that it genuinely took off.


  • Since it has been around for a lot longer than .NET Core, there is a considerably larger community and support system available.


  • Thanks to the CLR, you can run your programs in a very sophisticated environment.


  • It supports older programming paradigms and languages as well as more modern ones.

When to Use .NET Core

When creating apps to run on any platform, the ideal framework is .NET Core, which is open-source and cross-platform. For cloud apps or the conversion of substantial business programs into microservices, use .NET Core.


In the following situations, it makes sense to use .NET Core:

  1. Using Docker containers

    Microservices design and containers are frequently used in tandem. Container compatibility is excellent with .NET Core due to its lightweight and modular design. Cross-platform server programs may be deployed into Docker containers. Containers can also operate with the .NET Framework, although the image size is more significant.

  2. Both high-performing and scalable

    For optimal speed and scale, Microsoft advises using ASP.NET Core in conjunction with .NET Core. When employing hundreds of microservices, this becomes crucial. In this situation, fewer servers and virtual machines are preferable. Along with cost savings, the increased efficiency and scalability should result in a better user experience.

  3. Simultaneously using different .NET versions

    Designers must use .NET Core to install apps with dependencies on various .NET Framework versions. This allows several services running on various .NET versions to run on the same server.

  4. Control over command-line interface 

    Some programmers like using command-line interfaces and simple editors. On production, .NET Core needs only a minimum installation and offers a CLI for each supported platform. Additionally, it is still possible to switch to an IDE, such as Visual Studio IDE.

  5. Using microservices 

    Software programs made up of small, modular business services are known as microservices, a kind of SOA. Each service can run a distinct process, deploy autonomously, and be created using a range of programming languages. For each microservice, .NET Core supports various platforms and is lightweight and extensible.

When to Use .NET Framework

Windows comes pre-installed with the .NET Framework. As a result, .NET workflow and data connection technologies are typically used to create Windows desktops and extensive business applications.

Use of the .NET Framework is most practical when:

  1. The platform does not support .NET Core

    You may encounter some issues even with supported services; that is the way. Finding courses to learn and answers to problems you could encounter is becoming more difficult as .NET Core becomes more dominant.

  2. .NET Core does not permit the usage of other libraries

    Instead you can utilize NuGet packages. NuGet is a free and open-source package manager for Microsoft .NET and other development platforms.

  3. Technologies are not yet available in .NET Core

    Not all of the .NET Framework's technologies are supported by .NET Core. These emerging technologies include the following:

    • Web Forms apps for ASP.NET

    • Applications for ASP.NET Web Pages

    • Server/client implementation of SignalR in ASP.NET

    • Installation of WCF services

    • WCF Data Services, Workflow Services, and Windows Workflow Foundation (WF) are services linked to workflow.

    • Windows Forms and WPF are two examples of presentation technologies. 


A Quick Comparison Table

The following table compares the features of .Net Core and .Net Framework:

Features

.NET Core

.NET Framework

Cross-Platform

.NET Core is based on the philosophy of "create once, run anywhere." Due to its cross-platform nature, it is compatible with a number of operating systems, including Windows, Linux, and macOS.

Windows is the supported operating system for the .NET Framework. Nevertheless, it was created to support software and programmes on all operating systems.

Installation

Due to its cross-platform nature, .NET Core is packaged and deployed without regard to the underlying infrastructure.

The Windows operating system comes with a single package that installs the .NET Framework.

Application Models

.Net Core prioritizes the web, Windows Mobile, and the Windows Store rather than supporting the creation of desktop applications.

In addition to supporting Windows Forms and WPF programs, .Net Framework is used to create desktops and web apps.

Performance and Scalability

High speed and scalability are advantages of .NET Core.

When it comes to application performance and scalability, .Net Framework performs less well than .Net Core.

Android Development

Through the .NET Standard Library, .NET Core is interoperable with free and open-source mobile application development frameworks like Xamarin.

No framework for developing mobile applications is supported by the .NET Framework.

Conclusion 

The future of .NET seems bright and there is little question that the conflict between .NET Core and .NET Framework will persist. Your company model may influence your decision, even though both are efficient solutions and are preferred in various IT projects. 


Microsoft will continuously provide upgrades and changes to better both platforms, so you might be confused about which one to select. Hopefully, this blog has helped you see the distinctions between these two frameworks and decide which is best for you.
