.NET & ASP.NET Core Development
.NET Development Services with ASP.NET Core and C#
ASP.NET Core web applications and APIs in C#, Blazor front ends, .NET MAUI apps and integration with the Microsoft and Azure ecosystem.
ASP.NET Core Development Across the Microsoft Stack
If your business already runs on Microsoft — Active Directory, SQL Server, Office 365, Dynamics or Azure — then .NET is usually the path of least resistance. ASP.NET Core is fast, cross-platform and open source, and it integrates with that ecosystem without adapters or workarounds.
We build web applications, minimal APIs and background services in C#, with Entity Framework Core or Dapper for data access depending on the workload, ASP.NET Core Identity or Entra ID for authentication, and clean separation between domain, application and infrastructure layers. Blazor is an option when your team is stronger in C# than JavaScript and you would rather keep one language across the stack.
A large part of our .NET work is migration: moving .NET Framework applications off Windows-only hosting onto supported, containerised .NET, which usually brings a significant performance gain and removes a growing security liability.
What’s Included
What We Build with .NET
ASP.NET Core Web Apps & APIs
MVC, Razor Pages or minimal APIs with validation, versioning, OpenAPI documentation and structured logging.
Blazor Interfaces
Interactive front ends written in C# — Blazor Server or WebAssembly — sharing models with your back end.
Entity Framework Data Layers
EF Core or Dapper against SQL Server, PostgreSQL or Azure SQL, with migrations and tuned queries.
Microsoft Ecosystem Integration
Entra ID single sign-on, Dynamics, SharePoint, Power BI datasets and Office document generation.
.NET Framework Migration
Moving legacy ASP.NET and WebForms applications to supported .NET with containers and CI/CD.
Cross-Platform Apps with MAUI
Desktop and mobile clients in .NET MAUI when your team wants one C# codebase across platforms.
Benefits

FAQ
.NET & ASP.NET Core Development FAQs
Should we migrate from .NET Framework?
If the application is still on .NET Framework 4.x you are on a platform that receives only security fixes. Migrating to current .NET typically improves performance substantially, allows Linux and container hosting, and reduces licensing cost. We assess and migrate in stages.
Blazor or a JavaScript front end?
Blazor is a strong choice when your team is C#-first and the app sits behind a login. For public, SEO-driven sites or where you need the JavaScript ecosystem, React, Angular or Vue against a .NET API is usually better.
Can .NET run outside Windows?
Yes. Modern .NET runs on Linux and in containers, which is how we deploy most new projects — often at a lower hosting cost than Windows Server.
Can you integrate with Dynamics or Power BI?
Yes. We build integrations against the Dataverse and Dynamics APIs, and provide datasets or embedded reports for Power BI where reporting is part of the requirement.

Scheduling Software for Multi-Site Clinics: Rotas, Reminders and No Double-Bookings
When a clinic group grows past a few sites, separate diaries start costing patients and clinicians time. Here is what a group-wide scheduling system has to get right: resources rather than slots, double-booking prevention that holds under pressure, rotas across sites, reminders, waitlists and patient data protection.
When .NET Is the Right Choice for Your Web Application
.NET is fast, strongly typed and exceptionally well tooled. Here is where that genuinely matters, and where it is more structure than your project needs.

Angular makes more decisions for you than any other major framework. On a big, long-lived application maintained by a rotating team, that is the feature.
