NET Core vs .NET Framework: Which is Best for App Development

The debate between .NET Core and .NET Framework has been going on for a while. Knowing their main differences is important before choosing one for your app project. Each has pros and cons, making the choice challenging. This blog will discuss their main differences and help you decide which best suits your project.

Around 19.5% of global developers prefer working with skills specializing in the .NET Core.

What is the .NET Framework?

.NET Framework, made in the early 2000s, is a tool for building software on Windows computers. It comes with lots of ready-to-use code called Framework Class Library (FCL). It lets different programming languages work together.

.NET Framework mainly helps make Windows programs like Windows Forms, WPF, and ASP.NET. It’s reliable and has lots of useful stuff built-in. You can use it with different languages, but most people use C# and VB.NET with it.

What is .NET Core?

.NET Core, which came out in 2016, is a free, open-source framework that works on Windows, macOS, and Linux. It’s like a toolbox where developers can pick and choose what they need for their apps. It’s great for making modern web apps and cloud-based systems, like ones with several users. Plus, it works well with ASP.NET Core for building cool web apps.

Key Coding Differences in .NET Core vs .NET Framework

1. NET Core vs .NET Framework: Platform Compatibility and Open Source

.NET Framework .NET Core 
The dot net framework lets developers build applications for one platform, like Windows. It includes language compilers enabling you to write and utilize code in one language across multiple languages.Initially, Microsoft made the .NET Framework a proprietary and licensed framework, but later, they added new parts and made it open source. In contrast to the debate between .NET Core and .NET Framework, .NET Core offers cross-platform compatibility. This allows developers to adopt the “build once, run everywhere” approach and easily migrate applications to different platforms.Choosing .NET Core for enterprise app development is advantageous because it provides several useful features, including testing, debugging, project management, source control, and more.

2. NET Core vs .NET Framework: Installation

.NET Framework .NET Core 
The .NET Framework is like a one-stop shop. It includes everything necessary to create a Windows application. .NET Core works on several different computers and needs some basic things to run, like tools and stuff. You can install it on any computer and add more features as needed.

3. NET Core vs .NET Framework: Performance and Scalability

.NET Framework .NET Core 
.NET Core is better than .NET Framework for making programs run faster and handle more work. It offers high performance and scalability.

4. .NET Core vs .NET Framework: Mobile App Development

.NET Framework .NET Core 
The .NET Framework isn’t helpful for making mobile apps. This is a big problem because mobile apps are important for businesses today. .NET Core helps with every important step of creating mobile apps. With Xamarin, you can build apps for multiple platforms using C#, and you can use Xamarin tools to tweak your apps for different platforms.

5. NET Core vs .NET Framework: CLI Tools

.NET Framework .NET Core 
Using the Command Line Interface (CLI) can be tough. However, many developers still prefer it over Integrated Development Environments (IDEs). .NET Core comes with a simple tool called CLI that developers can use. You can also choose to use a different tool called an IDE if you prefer.

6. NET Core vs .NET Framework: Deployment Model

.NET Framework .NET Core 
The .NET Framework lets you only put apps on the Internet Information Services (IIS). Developers can also just copy the files to a folder to run using Xcopy deployment.However, this is good for small apps. But for big apps, putting them on the server can get complicated. with .NET Core is much more flexible. Developers can quickly update the current version to the latest one with new directories without disruption.Most importantly, you have the option to self-host the .NET Core app by creating a private hosting process or deploying it directly to the cloud.

7. NET Core vs .NET Framework: Deployment Model

.NET Framework .NET Core 
The .NET Framework is used to create REST services alongside supporting Windows Communication Foundation (WCF) services. It lets you develop and use REST services, but you must make a specific REST API to use microservices architecture.

8. NET Core vs .NET Framework: Microservices support

.NET Framework .NET Core 
.NET Framework doesn’t support the creation and use of microservices, but it does support REST API services. It allows developers to build microservice-centered systems reasonably quickly. It includes tools for building microservices and enables developers to craft REST APIs. The system comprises independent, resilient microservices, allowing the development team to select the most suitable approach for their business model.

9. NET Core vs .NET Framework: Security

Advantages and Drawbacks of .NET Core


  1. Works on different systems like Windows, macOS, and Linux.
  2. Faster than .NET Framework, good for speedy tasks.
  3. Keeps getting updates and improvements.
  4. Open for everyone to work on.
  5. Let developers use command lines for tasks.
  6. Easily manage projects.


  1. Has fewer ready-to-use tools and libraries.
  2. Doesn’t have as big a support community.
  3. It can’t handle web forms like the .NET Framework does.

Advantages and Drawbacks of the .NET Framework


  1. It’s been stable and reliable for a long time, which is good for businesses.
  2. There are lots of libraries with ready-made tools to make development faster.
  3. You’ll find abundant support and resources.
  4. It makes developing easy on Windows platforms.


  1. Not suiatble for macOS or Linux.
  2. It’s not as speedy as some alternatives.
  3. While Microsoft might not update .NET Framework as frequently as .NET Core, both frameworks offer valuable features.

Use Case Scenarios: What You Should Pick and When

You Should Choose NET Core when:

  1. Use microservices for better project management.
  2. Make it compatible with various platforms.
  3. Utilize a command-line interface (CLI) for your project.
  4. Begin a project from scratch.
  5. Ensure it’s fast and capable of handling large user loads.

You should choose NET Framework when:

  1. Apps used to run on the .NET Framework.
  2. Features that .NET Core lacks include Windows Forms, WPF apps, WCF services, ASP.NET web forms, and more.
  3. A reliable setup for an app is desired.
  4. Frequent updates and changes are to be avoided.

Which One is Better?

Thanks to technological advancements, the development of server-side applications has greatly improved in recent years.

.NET development services are reliable and scalable for building robust applications. With its open-source and cross-platform functionality, NET Core enables developers to create and deploy high-performance applications on any platform.


Both .NET Framework and .NET Core have their benefits and limitations; however, each offers unique advantages. The right choice depends on your project’s needs and how scalable you want it to be. The future looks bright for both, with updates to make them better.
