Hire .NET Developers Who Modernise Systems The Business Runs On
.NET estates rarely fail loudly. They just get harder to change each year until a small release needs a committee and a weekend. Stallyons is a Delaware-registered US company whose senior C# engineers work your hours, on one contract, with your IP signed before anyone gets access.

What Hiring .NET Developers Actually Involves
Hiring .NET developers usually means one of two jobs, and they are not the same job. One is building something new on .NET 8: services, APIs, internal tools, work that starts clean. The other is taking an estate that has been running since the Framework era and making it safe to change again. Most teams describe both as .NET work, then wonder why a developer who is strong at one struggles badly with the other. Ask which job you have first.
Stallyons is registered in Delaware as a US company, and our senior .NET engineers work inside a time-zone window you set, with four-plus hours of daily overlap. You sign a US contract, run diligence on a US entity and pay one US invoice, which matters when procurement and legal review a vendor before engineering ever meets them. The engineers on your account average four-plus years of production C# across line-of-business systems, APIs and Azure work, backed by twelve-plus years of delivery across six continents.
What .NET Developers Cover
ASP.NET Core services that stay serviceable: dependency injection used properly, thin controllers, a domain layer you can test without a database, and configuration that differs by environment rather than by comment.
Entity Framework that behaves under load: explicit loading rather than lazy surprises, projections instead of whole entities, and generated SQL somebody has actually read against a table with real row counts.
Modernisation in stages: a .NET Framework application moved to .NET 8 route by route, behind the same URLs, with the old system serving traffic until the new one has earned it. No flag day.
Azure work that fits the estate you already have: App Service or containers, managed identity instead of connection strings in config, and cost somebody can explain line by line.
Integration with the systems that already run the business: ERP, CRM, identity, reporting and the internal service nobody documented, connected through contracts rather than shared tables.
Testing that makes upgrades survivable: unit tests around the domain, integration tests over the data access, and a pipeline that fails before your users do rather than after.
Why Enterprise Teams Choose Dedicated .NET Developers
- Ask which .NET version their last three projects shipped on. Plenty of CVs say .NET without saying whether that meant Framework 4.8 or anything from this decade.
- Ask how they would upgrade a Framework application without a freeze. If the plan starts with a rewrite and ends in a big-bang cutover, you are buying a gamble.
- Ask what they do about lazy loading in Entity Framework. Anyone who has run EF under real load has a firm opinion and a story behind it.
- Ask how they structure a solution. Projects split by layer, dependency injection wired at the edges, and a domain you can test without a database or a web server running.
- Ask what happens to the Windows servers. Modernisation that ignores hosting, identity and deployment leaves new code stranded on infrastructure nobody will touch.
- Ask them to describe a rollback. Teams who deploy often answer in one sentence; teams who deploy quarterly describe a meeting and a change board.
How To Hire .NET Developers Properly
Every engagement starts with a free 45-minute technical session. No slide deck, no sales script. You bring the estate, the constraints and the roadmap; you leave with a recommended team shape, a clear scope and a timeline.
We are selective about new engagements and cap how many we run at once, because the vetting is the product. If we cannot staff your .NET work with engineers we would vouch for, we will tell you so.

Common Challenges
Why Do .NET Projects Get Stuck?
Six patterns behind almost every .NET estate that became slow and expensive to change. None of them are about the language.

Stranded On 4.x
01
The application still runs, so the upgrade never makes the budget. Then a library stops shipping fixes, a hosting version goes end of life, and the work happens anyway, faster and under pressure.

Upgrade Postponed
02
Each year the jump gets bigger. A move that would have taken a quarter three years ago now touches authentication, hosting, the ORM and half the tests.

The Untestable Core
03
Everything is wired through static helpers and direct database calls, so nothing can be tested in isolation. Changing one thing means retesting all of it by hand.

Dead-End Stacks
04
Whole features sit on WebForms, WCF or another dead end. There is no upgrade path from there, only a rewrite, and nobody wants to be the person who proposes it.

Lazy-Loaded Everything
05
Lazy loading can turn one page into hundreds of queries. The fix gets bought as a bigger database tier, the bill goes up, and the page stays slow because nobody read the SQL.

The Server Nobody Patches
06
One Windows server has run since before the current team joined. Nobody knows what breaks if it restarts, so it is patched by nobody and feared by all.
Recognise any of these? Let's cost the fix properly.
Six Ways To Hire Senior .NET Developers
Six ways to add .NET capacity from one accountable vendor. Run one, or run several in parallel under a single contract.

Dedicated .NET Developers
01
Named C# engineers who join your team, your board and your stand-ups, working to your review rules, with a lead who reports into you rather than around you.

ASP.NET Core Builds
02
New services and applications on .NET 8: clean project structure, dependency injection, tested domain logic, and deployment set up before the first feature ships.

Legacy .NET Modernisation
03
Framework applications moved to modern .NET in stages, route by route, with the old system serving traffic until the new one has earned the switch.

Azure Migration & Ops
04
Lift, re-platform or rebuild into Azure, with identity, secrets, monitoring and cost controls set up properly rather than discovered on the first invoice.

Integration & Data Work
05
ERP, CRM, identity and reporting systems connected through documented contracts, so a change on one side does not quietly break the other three.

.NET Support & Maintenance
06
Version upgrades, security patching, dependency updates and small features on a standing cadence, so the estate never drifts far enough to need a rescue.
Not sure which .NET engagement fits? Let's scope it together.
Why Choose Us
What Makes Hiring .NET Developers Here Different
The details that decide whether a .NET estate is still cheap to change in year five.

A US Legal Entity
01
Stallyons is registered in Delaware. Your contract, your invoice and your legal recourse sit with a US company, not an unknown one.

Build And Upgrade
02
We do both jobs. New services on .NET 8, and the unglamorous work of getting an older estate onto it, usually in that order.

Overlap You Set
03
You choose the hours we share with your working day, and stand-ups, reviews and escalations all happen inside that window.

Tested, Not Trusted
04
Domain logic under unit tests, data access under integration tests, and a pipeline that fails on our machines rather than on your users.

Reviewed Code
05
Every merge is reviewed against an agreed definition of done, on your board, where you can read it yourself.

One Contract
06
One contract covers the engagement, so procurement, legal and finance each deal with a single named counterparty.

"We came to Stallyons after burning two years and four vendors on a multi-platform launch that kept slipping. They scoped it end-to-end — web app, iOS, Android, an AI summarization layer, and a Shopify integration — and shipped it in 22 weeks. One team, one budget, one quality bar. We've handed them three more engagements since."
Mark Sawyer

"Stallyons rebuilt our customer-facing portal, integrated three legacy systems, shipped an AI document analysis pipeline, and brought our compliance posture to SOC 2 — all under one engagement. The senior engineers on the team have shipped at companies five times our size. It's the best vendor decision we've made in a decade."
