» C# ENSURES YOUR CUSTOM SOFTWARE STAYS RELEVANT

Simple and effective coding with C#

At Netgen, we use C# as one of our primary coding languages for all of our custom software projects. It was originally developed by Anders Hejlsberg
of Microsoft for the Windows .NET framework back in 2000, making C# a fairly young language in the world of custom software.

Just because C# is still considered the new kid on the block, doesn’t mean it isn’t incredibly powerful. In fact, because it is so modern and current, C#
is one of the best options there is for working on client solutions. Our team has found it to be incredibly versatile for a range of different custom
software projects, as well as being highly reliable in the long term.

Why Netgen uses C#

C# was designed to be a general-purpose coding language, meaning we can use the same language on a wide variety of different projects.

It’s one of the top 10 programming languages currently used around the world.

C# supports all of the major target platforms – Windows, Linux, macOS, Android and iOS.

C# can be used on both the .NET platform and on any open-source software, making it a dynamic and flexible choice for development.

All code in C# is statically typed, making it easier to spot errors before deploying the finished solution.

The software we create is simple to maintain and scale when needed thanks to the nature of C# coding.

Microsoft continues to use the coding language as their own primary language, meaning it will remain relevant for years to come. They’ve released 3 major upgrades in the last 4 years, as well as .NET 5.

C# is the Natural extension to MVC (Model View Controller) architectural pattern, which separates an application into three main components: the model, the view and the controller.

.NET has a Core modular, cross-platform, and open-source software development framework that is used to build Windows, Web and Mobile applications for Windows, Linux and OS X platforms and allows C# to be a truly multi-platform language.

Object-oriented programming (OOPS)

C# is an object-oriented programming language. This means:

The custom software solution is separated into small segments or responsibilities and each one is coded for that specific function. These are called classes.

A class is much smaller than a module of the software; it’s actually only one action or task within the software. In other words, each element within the software that needs to create an action is a class.

An easy example to visualise is in a form. If the software is for sales and shipping, it’ll need to have forms that users complete about the sale – name, contact details, payment details, etc. Each element of the form is a class.

The beauty of object-oriented programming is that once a class has been coded, it can be reused wherever it’s needed within the software. For example, wherever a user inputs their contact details in the software, the same piece of code can be used.

The relationship between each class is what makes the software work. Some classes will collaborate – work together to cause a specific action. Other classes will come together to make a larger object. In other instances, one class can be used to qualify another. Back to the contact details example – an address can be a billing address or a shipping address. The address class will be the same piece of code, and a new class will be added to qualify what type of address is needed.

The reason object-oriented programming is so powerful is that once a class has been coded, it can be used again and again within the solution. It’s also easy to spot where the errors in coding have been made because each class exists on its own. By testing the classes one by one, the developer can see where the error lies and fix it. This one fix can then be copied to every other instance where that class is used in the software.
