WHO WE ARE

A senior .NET team you can outsource to

FusionHit is where US teams outsource .NET without the cost and lead time of hiring in-house. Senior nearshore engineers, fluent in C#, ASP.NET Core, and Azure, work in your time zone as an extension of your team.

\
WHAT WE DO

.NET services we provide

One senior team across the full .NET lifecycle, from a new API to a Framework migration.

Custom .NET application development

Line-of-business systems and APIs in modern C#, built to be maintained.

.NET Framework to .NET 10 migration

Incremental strangler-fig moves with the Upgrade Assistant, route by route, not a rewrite weekend.

ASP.NET Core Web API development

Services designed for the clients that consume them, with versioning taken seriously.

Blazor application development

Web UI in C# for teams that would rather not run a separate JavaScript stack.

Azure migration and modernization

Windows Server and SQL Server workloads containerized and moved, with licensing cost in the plan.

Code audits and performance optimization

EF Core query tuning, sync-over-async remediation, and SQL Server blocking, fixed with evidence.

The team has been able to stay as a team for two years now. A single team, with nobody leaving. I've had a really stable team that I've seen grow in strength.

FAQ

FAQs about our .NET development services

01

Why outsource .NET development instead of hiring in-house?
Outsourcing gets you senior .NET engineers in days instead of the months a US hire takes, at 30-50% below domestic rates, and a migration team can scale down after cutover. If you would rather bring talent onto your own payroll, see hire .NET developers.
02

How much does .NET development cost?
It depends on team size, seniority, and engagement model (staff augmentation, a dedicated team, or full project outsourcing). Senior LATAM rates run 30-50% under US equivalents, with a line-item estimate on the first call and no hidden overhead.
03

Can you migrate our Web Forms and WCF services to .NET 10 incrementally?
Yes, and incrementally is the point. We use the .NET Upgrade Assistant with a strangler-fig approach, routing traffic between old and new side by side so there is never a single cutover weekend the business has to survive.
04

Which .NET versions do you support?
.NET Framework 4.x through .NET 10. We keep clients on LTS releases and are explicit about which of your components are past end of support today.
05

Blazor, React, or Angular on top of a .NET backend?
Blazor when your team is C# and wants to stay that way. React or Angular when you already have front-end talent or need the wider component ecosystem. We size the maintenance cost of each before you pick.
06

Can you tune our Entity Framework queries and SQL Server performance?
Yes: N+1 queries from lazy loading, missing indexes, blocking and deadlocks under load, and sync-over-async patterns inherited from Framework-era code. Diagnosis first, ranked fixes second.
07

What happens to our Windows and SQL Server licensing if we move to Linux containers?
It usually drops, sometimes substantially, but it depends on your agreement and which components can actually move. We model it as part of the migration plan rather than promising a number up front.
08

How fast can a .NET team start?
We present matched profiles within days, you approve them, and most engineers onboard in under 2 weeks, compared to the 3-6 months a typical US hiring cycle takes.
