Why Use .NET Core To Develop Your Technology

By gswardman February 17, 2023

As a developer, the availability of many platforms makes it hard to know which is best. We recommend that you consider using .NET Core. It’s different from the .NET Framework, so if you know how to use .NET, you’ll need to spend some time learning how to use .NET Core.

There are many reasons you should use .NET Core. Some of these reasons include cross-platform compatibility, its bugs are fixed quickly and modular design. Let’s look at why you should use .NET Core in detail as well as when to and when not to use it.

What Is .NET Core?

What Is .NET Core

.NET Core is a broad and improved or new version of the .NET framework giving it more cross-platform ability, modularity, and scalability. Microsoft says that .NET Core is a cross-platform implementation of the .NET framework.

With regard to cross-platform support, backend developers can build, test and deploy Windows OS apps as well as MacOS and Linux apps via Xamarin. .NET Core is also powerful enough to develop cloud, IoT (internet of things), and web apps.

In addition, one of the most substantial refinements of .NET Core over .NET is its open-source nature. As a result, developers can leverage the power of this NET standard library platform without paying huge amounts of cash in licenses.

This means that .NET Core can be used by just about anyone with development experience, making .NET Core the go-to NET development platform for various developers and companies for various application needs.

What Are the Benefits of .NET Core?

.NET Core is Multiplatform

.NET Core is the first true cross-platform development framework from Microsoft. Previously multiplatform meant that you could use it to develop apps for various Windows OS versions.

But with .NET Core, developers can design, build, test, deploy and maintain applications for Windows OS as well as macOS and Linux. This is a huge leap over its predecessors (.NET) with regard to efficiency and scalability.

This multiplatform ability is a welcome addition for developers who work on macOS and Linux. In the past, Mac and Linux developers would have to purchase Windows OS gear which would have cost them a lot of money and time.

.NET Core is Open Source

Microsoft has been trying out the open-source approach for some time now. The first time the company did it was with ASP.NET MVC. This approach has been carried on to .NET Core, including the platform’s documentation.

This is great news for developers looking to work with open web development platforms. In addition, open-source application development platforms rank highly with regard to dependability, flexibility, and security.

The open-source nature of the .NET Core application development platform means that any developer can make changes to this NET platform. If Microsoft deems the changes vital to the performance of the platform, they will be made permanent.

.NET Core is Suitable for Microservices

The design and building of software applications using microservices is gaining traction. Prior to microservices, the most commonly utilized approach for designing and building applications was monolithic, one service responsible for everything.

Fortunately, .NET Core supports development using microservices. Not only does .NET Core allow for microservices integration, but the process is also very easy and efficient.

Cross-platform compatibility also means that applications already built using the .NET framework can be used in macOS and Linux, which reduces infrastructure costs significantly.

.NET Core Outperforms .NET

The difference in performance between .NET Core and the .NET framework is like night and day. Why? Because .NET is restricted by its legacy System.Web library ecosystem.

This means that the .NET Framework supports older versions of .NET projects, which has limited its evolution. .NET Core, in contrast, has changed the rules of the game, making it a powerhouse with regard to performance.

In .NET Core Bugs Are Fixed Quickly

If you’ve ever encountered a glitch in the .NET framework and reported it, you know how long it takes for Microsoft to fix glitches. Sometimes it takes as long as one year for glitches to be fixed, and sometimes the updates don’t work.

In addition, updates rolled out to fix problems can cause issues elsewhere. This means if you find a bug in the .NET Framework, you’re better off looking for an alternative as opposed to waiting for a comprehensive solution to be rolled out.

With .NET Core, things are different because updates meant to fix problems are released quickly. How? Because .NET Core is open source, meaning a developer on GitHub can propose a solution if Microsoft’s team is unable to come up with a solution.

How to Use .NET Core?

How to Use .NET Core

As we’ve mentioned above, .NET Core is an open-source framework for designing and creating applications for the Windows platform as well as macOS and Linux. That said, here are the steps to follow to use .NET Core to develop apps on your device.

Start by Installing .NET Core SDK On Your Device

Before you start designing and creating apps using .NET Core, you need to install .NET Core SDL on your device. Download the latest version on the .NET website.

Generate A New Project

The second step to using .NET Core is opening a command prompt dialogue window and entering the following command (dotnet new console -n myApp). This helps you create a new application with the title ‘My App.’

Launch The Newly Created Application

The third step is running the application you’ve just created. To do this, go to the project directory and enter the following command (dotnet run).

Write Code

Now that you’ve built a new .NET Core application, the fourth step is writing code.

Publish the Application

After writing code for your entity framework core app, you can publish it. Use this command (dotnet publish -c release) to help you share the app with other developers.

When to Use .NET Core

You should use .NET Core under the following circumstances:

When You Need a High-Performance System

You should use .NET Core when you want optimal performance and scalability. This is especially handy when utilizing microservices side by side. In such an instance, all that’s need is a smaller amount of servers and virtual machine.

Apart from saving on costs, the competence and scalability you get from the .NET Core platform should equal a better end-user experience.

When You’re Running Several .NET Versions Concurrently

To build and deploy applications dependent on different .NET framework versions, you should use .NET Core. Why? Because NET Core allows for multiple services to be executed on a mono server-side containing multiple versions of the .NET Framework.

When You Want Control Over The CLI (Command Line Interface)

Some developers want control over CLI. Fortunately, .NET Core has a command line interface for everything it supports, and the installation is fast on machines. In addition, .NET Core allows for migrating IDE (integrated development environment) like Visual Studio.

When You Want Your App to Run On Various Platforms

You should also use .NET Core if you want your application to run on other platforms apart from Windows OS. These include macOS and Linux, which are supported as development workstations. What’s more, the list of supported operating systems is rapidly growing.

When Working with Docker Containers

Containers and microservices are often used together thanks to their modular design. .NET core works well with containers, which allows for the deployment of multiplatform apps to Docker containers. .NET framework is also compatible with containers, albeit bigger.

When Not to Use .NET Core

.NET Core lacks some of the inherent .NET features, and neither does it support all .NET add-ons and class library. For this reason, you will encounter some instances when using .NET Core might not be the best option. Some of these instances include:

When Building High-Performance Applications

When you’re building high-performance applications, it may be unwise to use .NET core because these apps might not run optimally. For instance, if you’re building an app for multiple mathematical computations, consider using programming languages like Java or Visual Basic.

When Building Large Applications

As discussed above, .NET Core is mainly used for cloud-based apps and microservices. As a result, it may not be the ideal pick for large apps that need a lot of legacy code.

When Building Windows-Only Apps

If you’re building an application to run solely on Windows OS, then there is no need to use .NET Core to build it. Remember, one of its key benefits is its cross-platform ability.

When Your App is Dependent on 3rd Party Libraries Not Compatible with .NET Core

If the application you’re building has dependencies on 3rd party libraries that aren’t compatible with .NET Core, you should use the .NET Framework.

When You Want to Establish a WCF (Windows Communication Foundation) Service

Currently, .NET Core doesn’t offer support for WCF. Instead, you need to establish an application programming interface using ASP.NET Core MVC.
