Overview

Enterprise .NET applications that run reliably at scale - on Azure and on-premises

We build .NET applications using ASP.NET Core, Blazor, WPF, and Entity Framework - following clean architecture principles and Microsoft's well-architected framework for Azure deployments.

DynamicUnit's .NET practice covers greenfield enterprise application development, legacy .NET Framework migration to .NET 8+, and microservices decomposition for existing monoliths. We're comfortable in Azure App Services, Azure Container Apps, and AKS - and we integrate naturally with the rest of the Microsoft ecosystem: Dynamics 365 F&O, Power Platform, Azure Service Bus, and Azure DevOps pipelines.

Need APIs to connect your .NET application to other systems? Our API development team delivers REST and GraphQL endpoints alongside the application build. For data-heavy or ML workloads, see our Python development practice.

Our Capabilities

Full-stack .NET development across the Microsoft ecosystem

From web portals and internal tools to high-throughput backend services - here's what our .NET practice delivers.

ASP.NET Core Web Apps

MVC and Razor Pages applications with clean separation of concerns, authentication middleware, and high-performance Kestrel hosting.

Blazor Applications

Interactive browser UIs using Blazor Server or WebAssembly - full .NET in the frontend without a JavaScript framework.

WPF Desktop Applications

Rich Windows client applications using WPF and MVVM patterns - for internal tools, operator interfaces, and data-intensive workflows.

Microservices & APIs

Domain-driven microservices with Azure Service Bus messaging, CQRS patterns, and API gateway fronting for enterprise backends.

Azure Hosting & DevOps

App Services, Container Apps, Azure SQL, and Blob Storage - provisioned with Bicep/Terraform and deployed via Azure DevOps pipelines.

Legacy Modernisation

Migrate .NET Framework 4.x applications to .NET 8 - improving performance, enabling cross-platform deployment, and unlocking modern libraries.

Dynamics 365 Integration

Custom .NET solutions that extend or integrate with D365 F&O and Business Central - dataverse connectors, OData clients, and custom services.

Security & Compliance

Azure AD / Entra ID authentication, role-based authorisation, data encryption at rest and in transit, and audit logging for regulated environments.

Why DynamicUnit

Why partner with us for .NET development

We live in the Microsoft stack - Dynamics 365, Azure, .NET - and we understand how these pieces connect in a real enterprise environment, not just on a whiteboard.

Deep Microsoft Ecosystem Knowledge

We work across Dynamics 365, Azure, Power Platform, and .NET - so your application integrates cleanly with the tools your business already uses.

Clean Architecture Principles

We apply domain-driven design, dependency inversion, and SOLID principles - so your codebase remains maintainable as it grows.

Azure-Native Deployment

Infrastructure as code, managed identities, Key Vault secrets, and Application Insights telemetry - Azure done properly, not just "it's in the cloud."

Tested & Documented Code

Unit and integration tests, XML doc comments, and architecture decision records are part of every delivery - not extras you have to negotiate for.

Migration Without Disruption

Legacy .NET modernisation is handled incrementally - strangler fig patterns, feature-flagged releases, and parallel-run testing to de-risk the transition.

End-to-End Delivery

From architecture design through development, Azure deployment, and post-launch support - one team owns the whole outcome, not just their slice.

How We Work

From architecture to production in 4 phases

1
Architecture & Scoping

We define the solution architecture, technology choices (.NET 8, Blazor, microservices vs monolith), Azure hosting strategy, and integration requirements. You get a fixed-scope proposal with a clear timeline.

2
Iterative Development

We develop in 2-week sprints with working demos at each milestone. CI/CD pipelines, test suites, and Azure infrastructure are set up from sprint one - not retrofitted later.

3
Integration & UAT

We connect to Dynamics 365, third-party APIs, and data sources. Your team runs user acceptance testing on a staging environment that mirrors production.

4
Go-Live & Support

Production deployment, Application Insights telemetry, knowledge transfer documentation, and ongoing managed support with named engineers who know your codebase.

FAQ

Common questions about .NET development

We build new projects on the current LTS release of .NET (currently .NET 8) and target .NET 9 where clients want the latest features. For modernisation engagements, we assess your existing .NET Framework version and plan a migration path - usually to .NET 8 - with minimal breaking changes to your business logic.

Yes - we've migrated several .NET 4.x applications, including Web Forms and classic MVC projects. The process starts with a compatibility analysis using the .NET Upgrade Assistant, followed by an incremental migration plan that keeps the application running throughout. We handle third-party dependency updates, namespace changes, and Azure deployment configuration.

Yes - this is one of our core specialisms. We build custom .NET services that integrate with D365 F&O via OData and custom services, and with Business Central via the Business Central API or AL extension. We also work with the Dataverse SDK for Power Platform integrations.

Blazor is a strong choice when your team is .NET-heavy and you want to avoid context-switching into a JavaScript ecosystem. Blazor Server is excellent for internal line-of-business apps with real-time data requirements. Blazor WASM suits scenarios where offline capability matters or you need a fully client-rendered experience. We'll recommend the right approach based on your team's skills and the application's performance requirements.

Infrastructure is provisioned as code using Bicep or Terraform and deployed through Azure DevOps or GitHub Actions pipelines. We configure Application Insights for telemetry, Azure Key Vault for secret management, and managed identities to eliminate stored credentials. Environments (dev, staging, prod) are separated from day one.

A focused web application or internal tool typically takes 6-12 weeks from architecture through go-live. Larger enterprise applications with microservices, multiple integrations, and Dynamics 365 connectivity run 3-6 months. Legacy modernisation timelines depend on codebase size and are scoped after an initial assessment. We provide a phased plan with clear milestones.

Cost depends on the application scope, number of integrations, and Azure infrastructure requirements. A focused internal tool or API project typically starts in the mid five-figure range. Enterprise applications with multiple modules and D365 integration run higher. We provide a fixed-scope quote after the architecture phase so there are no surprises.
