.NET Benefits

There are plenty of reasons why companies in need of tech solutions choose the .NET platform for their projects.

.NET is a powerfully progressive, open-source development platform that facilitates the development of everything from APIs to ERP systems. Businesses use the .NET framework to create secure, scalable web applications, desktop applications, mobile apps, cloud solutions, and enterprise systems.

Here are some of the benefits to using the .NET framework:


Free distribution & cross-platform development


.NET applications are designed to be highly scalable, allowing apps to handle a larger number of users and more data without compromising performance or stability


With household names like Samsung, Intel, and Dell using .NET, a large, supportive, vibrant community has grown around it, offering resources, forums, and libraries, whilst providing extensive support and fostering collaboration between developers


.NET projects have access to pre-existing solutions and tools which can accelerate the project’s timeline and increase developer productivity, including the Visual Studio, JetBrains Rider, and VSCode IDEs


Many .NET users experience increased productivity thanks to its large and thriving ecosystem


Modular apps to facilitate deployment & maintenance


A robust set of security features and mechanisms, including code access security, role-based access, cryptographic services, GuardRails, and more


Cleaner code with more focused units through the use of select patterns, principles and approaches including Object-Oriented Programming, Clean Architecture, Domain-Driven Design and Command Query Responsibility Segregation


Individual approach. Finally, if your company wants to develop custom software, you can enjoy an individual approach to software development. Companies such as SPG conduct an in-depth analysis of your business to build software tailored to your organisation, including specific internal workflows and processes.
