Main differences between .NET Core and .NET Framework

Introduction to .NET Core and .NET Framework

In this article, we are going to discuss the following topics: what is .NET Core and what is .NET Framework, main differences between them, assets and liabilities of .NET Core, Pros and Cons of .NET Framework, .NET Core vs .NET Framework. While the choice between .NET Core and the .NET Framework depends largely on the type of application and the platform on which it will be built, there are many factors to consider, including compatibility, performance, security, CLI tools, and more.

.NET Core vs .NET Framework: An In-Depth Comparison

Read on for an in-depth comparison between .NET Core and the .NET Framework. With .NET as its umbrella term, Microsoft supports two frameworks, including .NET Core and the .NET Framework. While the .NET Framework is a traditional and outdated version, the .NET Core was created to remove its limitations, bringing it in line with technological advances. But this does not mean that the .NET Framework is losing its fans.


For device and cloud workloads,.NET Core is a collection of runtime, library, and compiler components that can be used in different configurations. .NET Core is open source, cross-platform, and offers a lightweight development model as well as the flexibility to work with a variety of development tools and OS platforms. MIT-licensed versions of.NET Core are accessible on GitHub. ASP.NET Core, Entity Framework Core, and.NET Core are all included under the umbrella term ".NET Core."

The major and minor releases of.NET Core are related but distinct release streams. Major releases will contain little change and be extremely stable. A major release will be supported for three years or until the release of the following major release, whichever comes first. For instance, even though.NET Core 2.0 is a major update,.NET Core 1.0 will still be supported for a further 12 months.

The lifecycle of the parent release will be followed by ASP.NET Core and Entity Framework Core, which are shipped as parts of.NET Core releases.

It may occasionally be necessary to install a third-party component or library via NuGet before using .NET Core. The vendor that ships those libraries or components will be responsible for providing support for them.

Red Hat will instead publish.NET Core updates for some operating systems, like Red Hat Enterprise Linux. Updates for.NET Core for these platforms will be provided to the vendor for deployment through their systems.

Normally, there is a subset-superset relationship between.NET Core and the.NET Framework. Because it includes the essential components of the.NET Framework's runtime and framework libraries,.NET Core is called "Core." The GC, the JIT, and types like String and ListT>, for instance, are shared between.NET Core and the.NET Framework.

In order to make.NET open source, cross-platform, and usable in environments with fewer resources, .NET Core was developed.

Releases for .NET Core follow an agile, quicker release cadence because it is a more recent development platform. With a strict requirement for stability and compatibility,.NET Framework-based applications are widely used across hundreds of millions of computers. The.NET Framework is consequently released less frequently and with fewer changes. Because of these variations,.NET Core releases have their own lifecycle.

You don't need to update your application for.NET Core to work with.NET Framework 4.5.x or.NET 4.6.x. However, compared to the Microsoft.NET Framework, the.NET Core development platform has a number of advantages.

No, because both.NET Core and .NET Framework have advantages and disadvantages that we have already discussed, and we should make our decision based on the requirements of the project.

In the following situations, you shouldn't select or employ .NET Core:

  • Technologies like workflow, webforms, or WCF, which are not present in .NET Core, are needed by the applications.
  • Applications are created to only run on Windows.
  • Want to avoid dealing with ongoing upgrades and changes.

In the following situations, you shouldn't use or run the.NET Framework:

  • The project demands cross-platform integration.
  • Project requires the development of microservices.
  • Project relies heavily on CLI( Command Line Interface) as .NET Core is suitable for CLI.

C# is a programming language, .NET is a blanket term that tends to cover both the .NET Framework (an application framework library) and the Common Language Runtime which is the runtime in which .NET assemblies are run.

Existing .NET Core-based products won't be fully updated for a few years. Despite the fact that there are many .NET developers available, the ASP.NET Core framework represents a significant improvement over the ASP.NET Framework in terms of changes and new ideas.

Working with more contemporary libraries and programming languages is quicker with .NET Core. You can use various .NET versions in the same project, and it is more lightweight and modular than the .NET Framework.
