.NET Core Vs .NET Framework—Which Runtime Suits Your Business

.NET Core vs .NET Framework: Overview and Comparison

Microsoft’s .NET is a free, open-source developer platform for building many different types of applications. With .NET, you can make use of multiple languages (C#, F#, or Visual Basic), libraries, and editors to build web, mobile, desktop, gaming, and IoT applications.

The .NET open-source community is huge. Over 50,000 developers from more than 3700 companies outside Microsoft contribute to the community. For building server-side applications, .NET has two supported implementations: .NET Framework, which has existed for a few years now, and .NET Core, a very recent offering.

Both of them share similar components and it is often confusing to many to decide which one to choose for their project.

VS Trend

While the choice between .NET Core vs .NET Framework essentially depends upon the type of application to be built and the platform on which it is to be built, there are many factors that must be considered before choosing a framework for your next web development project. A few of these factors are discussed in the blog.

Performance

When a performance-oriented and scalable system is the topmost priority, who wins the .NET Core Vs .NET Framework performance battle?

When it comes to .NET Core, ‘Performance’ is its biggest benefit. The code compiled in .NET Core gets automatically optimized, without any need to change the code. The re-compilation feature of .NET Core optimizes the code directly, thereby increasing the performance.

One of the tests and studies conducted by TechEmpower reveal that .NET Core’s performance is 859 times faster than its previous performance records. This amazing result proves that .NET Core is here to stay for time immemorial and gives a long-term commitment to .NET Core web application development world.

TechEmpower writes:

“Thanks to Microsoft’s herculean performance tuning effort, ASP.NET—in the new cross-platform friendly form of ASP.NET Core—is now a top performer in our Plaintext test, making it among the fastest platforms at the fundamentals of web request routing. The degree of improvement is absolutely astonishing…”

When compared to .NET Framework, .NET Core is more robust in nature because of its faster, flexible, and secure nature. Consisting of NuGet packages, .NET Core framework gets transformed into a very light-weight framework, resulting in high performance.

Respond Per Sec

However, this does not imply that the .NET Framework lags behind in performance parameter. There are still many .NET Framework functionalities missing in .NET Core. And when there is a need to inculcate these technologies in the project, .NET Framework outsmarts its little sibling. These not-yet-available technologies include:

Deployment Model

One of the most important features available in .NET Core is its flexible deployment model. It means whenever the latest version of .NET Core gets launched, it can be instantly updated on one machine at a time, thereby getting uploaded in new directories without affecting the existing app. Moreover, .NET Core can also be deployed for apps that need more isolation using the new app bundling tools integrated into it.

Deployment Model

When it comes to .NET Framework, the web application needs to be deployed only on the Internet Information Server. However, the web applications built in .NET Core can be hosted in a number of ways, making it much more flexible than its counterpart.

Focus on All Devices

In today’s highly progressive digitized tech-friendly world, no matter what the business domain of an application is, at a certain point it becomes essential to build an app that can reach different markets and end users, wrapped in the latest technology. And .NET Core aims to achieve this target–to develop apps in a multitude of domains, such as gaming, mobile, IoT, AI.

Multitude of Domain

.NET Core and its new versions aim to focus on IoT devices, desktop devices, and AI-enabled devices. And with the .NET Core 3.0 update, Microsoft has given hints to the community that it may plan to kick out .NET Framework and replace it with the Internet of Things (IoT). But is it really going to happen?

Microsoft has cleared its intentions that it has no plans to replace the formidable .NET Framework. Rather, they are planning to slower releases of the .NET framework to maintain its compatibility. On the other hand, .NET Core updates are released faster to allow side-by-side configuration.

The intentions of Microsoft to delve deep into AI can be proven from its recently announced collaboration with SWIFT, the world leader in secure financial services. All businesses, today, are starting to invest in integrating such components in their applications.

So, if you are planning to go ahead with building an app that embraces the latest technologies, .NET Core is a perfect choice. When it comes to using free libraries, you can choose from millions of public and private packages on NuGet and MyGet. You can also integrate them into other apps by using the IDE or the CLI.

Cross-Platform Compatibility

The best thing that makes .NET Core the number one in its league is its compatibility with various operating systems—Windows, Linux, and even Mac platforms. The .NET structure was fully re-architected to give birth to .NET Core that can help you develop your applications on all platforms.

When it comes to .NET web development services for enterprises, it is a basic necessity that it supports all platforms. And .NET Core is cross-platform, which means, it is pretty easy to develop applications that run smoothly on Mac, Linux, and Windows. It also helps businesses with more exposure to other platforms.

On the other hand, the .NET Framework enables developers to build applications for a single platform—Windows.

When you start to create an application, you embark upon a journey with a few things already settled. One of them is an Operating System that your to-be app targets. And this decision is driven by factors like market, end users, or in a few cases, even your development team.

So, if you have a plan to come up with an application that is compatible with all the operating systems, go ahead with .NET Core and if you have decided that your app will target a single operating system, Windows, .NET Framework will do its job reasonably well.

IMG and its Successful Journey with Net Solutions

We helped IMG to deliver an application that would automate the merchandise approval and licensing processes with vendors. IMG wanted a B2B web app that would be compatible with all the operating systems and devices. Thus, we used .NET Core as the programming language for developing a web application with SQL Server as the backend and we worked on developing the front-end using JavaScript, JQuery, HTML, and CSS.

The result was that IMG was able to roll out an internal application that helped its staff become more efficient with their vendors. This feature brought transparency throughout the process of licensing and approvals.

Successful Journey

So, How to Choose between .NET Core and .NET Framework When it Comes to Runtime?

“That’s best of both worlds,” Galloway said, “because if I’ve got a stable existing platform, I can opt in to new features, I can kind of light those up, and if I’m doing new development I can jump right into .NET Core, but if I have existing code I can say, ‘ooh, I would like to use these cool fast features or these new exciting features, I can pull those into my .NET Framework apps.'”
~ Jon Galloway, Senior Program Manager, .NET Team, Microsoft

Cost-Effectiveness

When choosing the appropriate framework for your application, one of the first factors that must be pondered upon is the IDEs and the tools that are either compulsory for the chosen technology or simply make developers more productive. There are many that are free, but the best ones definitely come with a price tag.

No matter, if you are a startup trying to find your place in the market, or a big organization that’s already there, the money can be utilized in a better way somewhere else, with a better return.

The infrastructure of .NET Core opens up a multitude of hosting options, wherein you get the freedom to switch to Linux and to pick a provider of your choice that offers you a great SLA or is cheaper.

.NET Core vs .NET Framework—A Battle between Two Generations

When you are on the verge of starting a new project, it is definitely worth thinking as to which framework will best suit your project requirements.

When it comes to .NET Core, it is definitive that for the next decade or so, the latest and greatest features will appear on this platform. However, .NET Framework will give you a stable platform to build a robust application, which may be behind the .NET Core in terms of cutting edge features and innovations.

So, in the end, it’s not so easy to pick one amongst the two formidable frameworks. It all depends upon your project requirements, whether to go ahead with .NET Core or .NET Framework.
