Get in touchWhether you're developing new bespoke software or extending existing software with .NET Development, 6B brings the software expertise and experience needed to accelerate delivery.
From cross-platform web applications and backend services to integrations with Microsoft ecosystems and cloud-native architecture, our .NET development team works across the full stack to deliver solutions that are tailored, tested, and production-ready.
.NET is one of the most trusted and mature frameworks in enterprise software development. Backed by Microsoft, it provides a flexible, high-performance foundation for building secure, scalable applications that work seamlessly across platforms and environments. Whether you’re developing a customer-facing web portal, internal business tools, or cloud-integrated microservices, .NET offers the structure and power to support long-term business growth.
As a .NET development company, we help clients use the framework to its fullest — from leveraging the speed and modularity of .NET Core to integrating with Azure cloud services, Active Directory, and Microsoft’s wider technology stack. .NET’s compatibility with C#, strong typing, and powerful development tools make it a go-to choice for organisations that need reliability, maintainability, and enterprise-level performance.
We work with clients across industries — including finance, energy, logistics, and the public sector — to deliver software solutions that can handle high volumes of data, complex business logic, and strict compliance requirements. .NET is particularly well-suited for large-scale applications where consistency, testability, and integration are critical.
Our .NET development process starts by understanding your goals, challenges, and system environment. We collaborate with your stakeholders to define requirements, select the appropriate architecture, and design a scalable solution that supports both current needs and future growth. This may involve greenfield development, reengineering legacy .NET systems, or integrating .NET components into a wider technology ecosystem.
We architect software using best-practice patterns such as layered architecture, microservices, and API-first design. Our development team follows modern engineering practices including version control, automated testing, CI/CD pipelines, and containerised deployment — ensuring your application is stable, secure, and easy to manage in production.
Whether we’re building with ASP.NET Core, Entity Framework, or integrating with SQL Server, Azure, or third-party APIs, we focus on writing clean, efficient, and testable code. We work in agile sprints to maintain momentum and flexibility, delivering working software in incremental stages with full transparency and collaboration throughout.
We also support ongoing maintenance, optimisation, and feature development — ensuring your .NET application continues to perform reliably over time and can evolve alongside your organisation’s needs.
