Enterprise .NET development, modernized & AI-ready.

Two decades of Microsoft-stack engineering, now agent-accelerated. We modernize aging .NET Framework applications, integrate AI where it pays, and run the result on enterprise-grade hosting — one accountable, senior-led team.

The Modernization Problem

Your .NET application isn’t old. It’s unattended.

An enormous share of American business still runs on .NET applications built between 2005 and 2018 — WebForms and MVC front ends, Web API back ends, SQL Server underneath. They work. That’s exactly why nobody touched them. But .NET Framework is frozen at 4.8, the engineers who love WebForms are retiring faster than they’re being replaced, security reviews get harder every year, and every AI initiative your company wants runs straight into a codebase that can’t support it.

The industry’s default answers are both wrong: ignore it (the risk compounds), or green-light a full rewrite (the graveyard of two-year rewrites is vast and expensive). The disciplined path is incremental modernization — strangler-pattern migration from Framework 4.x to .NET 8, piece by piece, with the application running and earning the whole time.

That’s the work we do. NW eSource has built on the Microsoft stack since 2003 — and today we deliver it senior-architect-led and agent-accelerated, which changes the economics of modernization entirely.

What we modernize

.NET Framework 4.x · WebForms · ASP.NET MVC · Web API · VB.NET · Entity Framework · worker services · SQL Server–backed line-of-business systems

Where it lands

.NET 8 · ASP.NET Core · Azure or your cloud · modern CI/CD · observability · an architecture AI features can actually plug into

How we work

Fixed-price assessment first · phased roadmap with straight numbers · strangler-pattern increments · your team involved throughout · flat-rate hosting after

Enterprise .NET, End to End

.NET development — and everything an enterprise system needs around it.

Development, modernization, AI, hosting, and security under one accountable roof — no handoffs between vendors who blame each other.

🔄

Legacy Modernization

Framework 4.x to .NET 8 via strangler-pattern migration — value ships every increment, the application never stops running, and there is no two-year rewrite cliff.

🤖

AI Integration

LLM capability inside your existing .NET systems — document intake, summarization, internal copilots over your SQL data — on Azure OpenAI or your own tenant, security-first.

💻

Custom .NET Development

New builds in ASP.NET Core: APIs, integrations, worker services, and the line-of-business applications your operation actually runs on.

🛡

Enterprise Hosting

Azure or dedicated infrastructure — monitored, patched, backed up, and run by the team that built the system. We operate what we ship.

🔐

Security & Compliance

Identity, secrets management, least-privilege access, audit trails — architecture informed by CCSP- and Security+-certified engineering, not bolted on after.

🛒

.NET Commerce

nopCommerce and custom ASP.NET Core storefronts for catalog-heavy retail and B2B — we run production .NET commerce today, not theoretically.

Who Does The Work

Senior-architect-led. Agent-accelerated.

Every engagement is led by our principal .NET architect — twenty-plus years of enterprise Microsoft-stack engineering: data acquisition and ETL platforms, scheduling and reporting systems, production e-commerce, and large SQL-backed line-of-business applications. Certifications across the stack that matters: CCSP, CompTIA Security+, Azure, AWS Solutions Architect, Elastic Certified Engineer, ITIL 4, and a master’s degree in data analytics.

Delivery is agent-accelerated: AI coding agents working inside disciplined review loops — constraints, context, and human sign-off on every change — which multiplies senior engineering hours without multiplying senior engineering rates. You get the velocity of a team with the accountability of one architect.

We are deliberately small. Limited concurrent engagements, assessment before commitment, and no offshore handoffs — we’d rather do a few enterprise builds exceptionally than many adequately. If the fit isn’t right, the assessment says so and you keep the roadmap.

A legacy engagement, honestly
Where it starts

A 12-year-old Framework 4.x application the business depends on daily. The developer who built it is gone. Security wants answers, the framework is end-of-road, and the AI roadmap is blocked.

Where it lands

The same system on .NET 8 — migrated in increments while it kept running — observable, patched, hosted on managed infrastructure, with its first AI-assisted workflows live and a team that answers the phone.

Why assessment-first
The industry default

A sales team quotes a rewrite before an engineer ever reads your code. Eighteen months later the budget is gone and the old system is still in production.

Our default

A fixed-price assessment: an architect actually reads the codebase, maps risk and dependencies, and hands you a phased roadmap with a straight number per phase. Yours to keep, whoever you hire.

In Production

Proof that runs every day.

Not slideware — systems with real users and real uptime, built and operated on the Microsoft stack:

.NET FAQ

Questions enterprise teams actually ask.

What does a .NET modernization engagement cost?

It starts with a fixed-price assessment — an architect reads your codebase, maps risk and dependencies, and delivers a phased roadmap with a straight number per phase. You approve phases individually, so you never sign up for a two-year unknown. Agent-accelerated delivery keeps senior-led work at rates well below what a bench of consultants costs.

Do we have to rewrite everything at once?

No — that’s the approach we exist to prevent. Strangler-pattern migration moves your application from Framework 4.x to .NET 8 in increments: each piece is extracted, modernized, and shipped while the rest keeps running in production. Value lands every increment, and there’s no big-bang cutover risk.

Can you add AI to our existing .NET application without a rewrite?

Usually, yes. Document intake, summarization, search, and internal copilots over your existing SQL data can be integrated against a Framework-era system through well-defined service boundaries — on Azure OpenAI or your own tenant, with security reviewed first. Full modernization makes it easier, but it isn’t a prerequisite for the first wins.

Can you work with our in-house development team?

Yes — two common shapes: we take architecture and the hard parts while your team keeps feature velocity, or we deliver end to end in your repositories and CI/CD with your team reviewing. Either way your engineers finish the engagement knowing the modernized system, not locked out of it.

Where are you located — and do you offshore?

Portland, Oregon — we meet onsite around the metro and work remote-disciplined for everyone else, on U.S. hours. No offshore handoffs: the architect who scopes your system is the one accountable for delivering it.
