.NET Development & Modernization

We build new systems on current .NET and modernize the ASP.NET Framework, MVC, and Web Forms applications businesses already run on - the same discipline whether it's a greenfield API or a 15-year-old codebase nobody wants to touch.

What we build

What We Actually Build With .NET

  • New business applications and internal systems on current .NET (.NET Core 8, the active LTS release)
  • Phased migrations off ASP.NET Framework, MVC 5, and Web Forms onto current .NET
  • REST and Web APIs in ASP.NET Core, including CQRS/MediatR-based architectures for systems with real complexity
  • Multi-tenant SaaS backends and GIS-heavy, data-intensive line-of-business systems

Technical depth

.NET Work We Actually Do

.NET Framework to .NET Core migration

Incremental migration off .NET Framework 4.x using the strangler-fig pattern, not a single risky cutover.

ASP.NET MVC & Web Forms modernization

Server-control and ViewState-based Web Forms apps rearchitected onto ASP.NET Core with a modern frontend.

CQRS / MediatR architectures

Command/query separation for systems where a simple CRUD layer stopped being enough.

Entity Framework & Entity Framework Core

Data-access layers built or migrated on EF6 and EF Core, including systems with heavy GIS and spatial data.

API design in ASP.NET Web API / ASP.NET Core

REST APIs designed for the integrations a business already depends on, not just the ones planned today.

Windows desktop and internal-tool assessment

Windows Forms and WPF applications assessed for a realistic path to the web, not assumed to need a rewrite.

How we approach it

Migration & Implementation Patterns

01

Assess the existing .NET codebase, dependencies, and data model before any migration work starts.

02

Classify each component as Keep, Refactor, Replace, or Rebuild rather than defaulting to a full rewrite.

03

Migrate incrementally using the strangler-fig pattern, running old and new side by side during transition.

04

Validate each increment - functional, regression, and performance testing - before it takes over production traffic.

05

Cut over in phases with a defined rollback plan at every stage, not a single big-bang release.
