.NET Development

Custom .NET and C# software for the parts of your business where off-the-shelf tools stop short. Web, desktop, mobile, and integrations.

What's included

  • Custom web applications in ASP.NET Core and Blazor
  • Line-of-business desktop applications in WPF or WinUI
  • Cross-platform mobile apps with .NET MAUI
  • Web APIs and integrations with internal and third-party systems
  • Azure-native services with Functions, Service Bus, and SQL
  • SharePoint and Microsoft 365 extensions via Graph and SPFx
  • Modernization of legacy .NET Framework applications
  • Fixed-fee scoping with written specifications before a line is written

What we deliver

Custom software is the right answer when your process is the differentiator and forcing it into a packaged tool would cost more than building exactly what fits. It’s the wrong answer when it would just rebuild what Microsoft 365, Power Platform, or a SaaS product already does well.

We pick projects we can scope and ship. Most of our engagements are line-of-business applications: internal tools, customer portals, integration layers between systems that don’t talk natively, custom workflows that go beyond what Power Automate handles. Always C# and .NET, deployed to Azure where the host lives close to the rest of the Microsoft stack.

Where we typically start

Scoping is where most custom development goes wrong, so we treat it as a paid first phase:

  • Stakeholder interviews to understand the actual process, not the wished-for one
  • Technical assessment of integrations, data sources, and existing systems
  • Wireframes and a written functional specification
  • Architecture choices documented with their tradeoffs
  • A fixed-fee or capped time-and-materials proposal

You get a specification you can hold us to. Scope changes happen in writing.

Common engagements

Internal line-of-business apps. The web app that replaces a sprawling spreadsheet. The portal that gives field staff a clean interface to data trapped in three back-end systems.

API and integration work. Connecting your accounting system to your CRM. Pulling data from a vendor’s API into SharePoint or SQL. The integration layer that keeps three internal systems in sync.

SharePoint and Microsoft 365 extensions. When the out-of-box features stop short, custom SPFx web parts, Graph-API-driven Teams apps, or Power Platform connectors fill the gap.

.NET Framework modernization. Existing application stuck on .NET Framework? We assess, plan the migration to .NET 8 or later, and ship in phases without breaking the working parts.
