Dotnet Framework Vs. Dotnet Core – comparing these two frameworks will always remain a classic encounter amongst experts and developers. What is the core difference between Dot Net Framework and Dot net Core? Should I switch from Dot Net Framework to Dotnet Core or vice versa? Well, these are a few common queries that will keep haunting the developer community until they understand the fundamental difference between .NET Framework Vs .Net Core.

Maybe that’s the prime reason that forced me to start this blog, and I can assure you that you will come up with a clear perception by the end of this blog regarding Dotnet Framework Vs. Dotnet Core.

So, let’s start with a quick introduction on;

Dot Net Framework

The Dot Net framework was designed and developed by Microsoft in 2000 to help developers build web applications, desktop applications, windows applications and games for windows.

The initial version of .NET framework 1.0 was released in 2002. Gradually, it has come a long way with on-time functionality upgrades, and now, we have the primary version of .NET framework 4.7.2, available for use on its official website.

The two most essential components of the Dot Net framework are;

  1. Common Language Runtime (CLR)
  2. Extensive Class Library

Overall, the Dot Net framework is an object-oriented, closed source framework that supports multiple programming languages and gives .Net developers the necessary components to build dynamic applications.

Dot Net Core

The Dot Net Core is a cross platform-specific, open-source framework developers build cloud-based and IoT applications for multiple operating systems such as Windows, Mac, and Linux.

The .NET framework is compatible with programming languages like C#, F#, and Visual Basic to create robust apps and libraries.

Using .Net Core, developers can build high-performance web, multiple APIs and components, AI applications, mobile games, mobile apps, cloud applications, etc.

Dot Net Framework Vs Dot Net Core Comparison

Platform Compatibility

The .NET framework allows developers to build apps only on the Windows platform, whereas .NET Core comes with cross-platform compatibility. Developers can build apps for Windows, Linux and Mac using .NET Core.

Code Compilation

You can easily access and compile programs written in the .NET framework from one programming language into another. However, the program written using .NET Core is ready to migrate from current applications to other platforms.


The Dot Net Framework released was backed by Microsoft. Hence it is a closed source, object-oriented framework, apart from a few open-source components. But, DotNet Core is an all-in-one open-source framework with an easy accessibility component.

Deployment Model

.Net Framework developers can only deploy their applications through an internet formation server. But for that, they need to copy those files using XCopy deployment to the intended directories. That too, small and straightforward applications, and not complex and large applications.

.Net Core framework, on the other side, offers flexible deployment. You can instantly update and upload the latest .NET Core version on many devices and platforms without affecting the previous ones.

Apart from that, the apps created using .NET Core can be directly deployed via the cloud, or the developers can create self-host or custom hosting processes.

Performance & Scalability

When it comes to performance, .NET Core is a clear winner. Apps built in .NET Core are way better in performance than apps built on the .NET framework. With the .NET Core, developers can improve the performance of their developed apps without the additional hardware with the help of the automatic recompilation feature.

Also, .NET Core developers have the additional advantage of building, testing, and deploying apps directly on the cloud servers, which automatically improves performance and scalability.

Library Collection

Applications developed using the .NET Framework have the in-built class libraries that enable quick and easy operations on graphic rendering, file reading and writing, DB manipulation and XML doc manipulation. You can do the same with the .NET Core as well.

However, .NET Core comes with a redesigned common language runtime called CoreCLR, allowing developers to choose, pick and include only the required libraries to build their applications.

What to Choose and When? 

.NET Framework

You can choose Dot Net Framework when working on big and complex applications that require minimal modifications. You can also extend your ongoing app development by adding new features or services built on ASP .NET Core.

However, when your application API surface becomes more extensive and needs packages like NuGet or any other libraries that are not compatible with .NET standard libraries, you can use the .NET Framework precisely.

Lastly, you need to check that most platforms and services are not compatible with the .NET core like the Azure services. That’s where you should continue with the .NET framework.

.NET Core

As you know, .NET Core is a cross-platform specific framework; you should use it while working on multiple platform projects. Here, the command-line interface (CLI) is well supported by all supported platforms.

However, you can choose to use .NET Core while developing high-performance and scalable apps. While developing such apps, you have the advantage to select multiple microservices accordingly.

Microservices are small software applications that help build service-oriented architecture—all unique and independent of each other.

Final Thoughts

Since its release, .NET has been responsible for developing high tech applications that have shaped any enterprises’ technological prospect. It could be the next most adaptable framework in the upcoming days.

As of now, it’s running at a steady pace amongst enterprises, helping them provide cutting-edge web and app development solutions to their clients.
