.NET Core vs .NET Framework: How to Pick a .NET Runtime for an Application.

What is .NET Core?

.NET Core is a general purpose, free and open source development platform that helps developing cloud based applications like Linux, Windows, MacOS OS. As Microsoft’s latest version, it is a cross-platform, lightweight, fast and modular framework. Licensed under MIT, .NET Core framework can be used to develop different applications like games, microservices, machine learning, desktop or mobile versions etc. Some important features of .NET Core development services include:

  • Multiple development modes and environments
  • High performing
  • Open-source
  • Cross Platform

What is .NET Framework?

Developed and designed by Microsoft, .NET framework is a virtual environment for executing and compiling different programs written in VB.NET, C# etc. This can be used to develop web services, web-based applications and form-based applications. It supports around 60 programming lanuguages, out of which 11 are developed and designed by Microsoft. Basically, it includes programming languages, developer tools and libraries that are used to develop applications.

Components of .NET architecture

There are four major components of .NET architecture which are explained below.

1. Common language specification (CLS)

CLS enables the interoperability of .NET architecture where the objects implemented work anywhere. CLS is a subset of Common Type System (CTS)and therefore the rules are common to both. CLS ensures that the objects implemented has some sort of commonality.

2. Framework class library (FCL)

It is a comprehensive collection of reusable interfaces, classes and value types. FCL is inetgrated with Common language runtime (CLR) and is compatiable with all .NET languages including Visual Basic .NET, C#, F# etc. There are three main categories in FCL such as frameworks, wrapperaround OS functionality and utility features written in .NET.

3. Common language runtime (CLR)

CLR is the virtual machine component of Microsoft that undertakes the managment and execution of .NET programs. Basically, it is a runtime environment where the code conversion to native form occurs. To optimize the performance of CLR, ther are timely and routine updates.

4. Visual Studio

Visual Studio is a standalone source code editor that is used to develop web apps, mobile apps, websites, web services and computer programs. Visual Studio is used for debugging and building cloud and web applications.

.NET Core vs .NET Framework

1. Application types
.NET works fine with web as well as desktop applications. However, the same cannot be said for .NET Core. It does not work on desktop applications and can be used only for cloudbased or server-side applications.

2. Operating systems

.NET Core is a cross-platform framework and works with MacOS, Linux and Windows. However, .NET works only on Windows.

3. Installation

.NET is a single package and has all the necessary components that a developer requires. On the other hand, .NET Core comes in modules and has only basic components. Developers have the free rein to choose the compoents which they would require to build applications.

4. Microservices support

.NET only supports the REST API and not microservices. By contrast, .NET Core supports both microservices and REST API.

5. Deployment

Automatic updates occur on .NET Core. However, the updates in .NET are done first on Internet Information Server which the developer should manually update to the environment.

6. Mobile development

.NET never works on mobile development. On the contrary, .NET Core supports Xamarin and other platforms for mobile development.

NET Core Vs .NET Framework – Which is Better?
The answer to this purely depends on the basis of your project requirement. However, as the leading .net core development company, we can help you choose easier.

Choose .NET Core if

1. Project is dependent on Command Line Interface

2. Requires microservices

3. Cross platform integration is necessary

Choose .NET if

1. requires only Windows

2. Need technologies like WCF, webforms, workflow etc.

3. already executed on .NET

When to Use .NET Core

From our expertise in .net core development services, we recommend .NET Core to be used while working with docker containers, using microservices, and cross platform requirements. .NET Core is also a neccessity when you need scalable and high performing systems.

When Not to Use .NET Core

As the top .net core development company, we have a few recommendations on when not to use .NET Core. You cannot use .NET Core when you want to create a WCF service, or require Windows specific APIs. Moreover, you need to keep in mind that there are many .NET Core missing features and no third party library support.


As an expert asp .net core development company, we have presented to you the two sides of the raging debate on .NET and .NET Core. We are a dotnet core development company and have expert personel working on .netcore development services.
