.NET Developer Staffing for Microsoft-Stack Teams
Vetted senior C#, ASP.NET Core, Azure, and SQL Server engineers for enterprise Microsoft-stack work. Contract, contract-to-hire, and direct hire placements across the US.
.NET Hiring Is a Two-Stack Problem
A “.NET developer” used to mean one thing. Write C#, ship a Web Forms app, maintain a Windows service. That era’s over. The 2026 market splits into modern .NET and legacy .NET Framework, and a hiring loop that ignores the split usually ends with a wrong-fit finalist and a re-open.
Modern is .NET 8 and .NET Core. ASP.NET Core minimal APIs, Blazor for internal admin, Entity Framework Core, Azure App Service and Functions, SQL Server or Postgres, plus enough React or Angular on the front to wire up a UI. Legacy is the older estate. .NET Framework 4.x, classic ASP.NET MVC, WCF, WinForms and WPF desktop, on-prem SQL, and the maintenance work that doesn’t make it into conference talks. Same IDE. Different engineer.
Most staffing firms blur the line. They search “C# developer” on LinkedIn, send the first ten resumes, and hope the technical screen sorts it out. We don’t. Our IT staffing practice keeps the two benches vetted separately. Per the 2024 Stack Overflow Developer Survey, C# sits in the top five most-used languages among professional developers. The supply isn’t the problem. The matching is.
.NET Roles We Fill
Six searches we run on repeat. The titles shift by client, the work doesn’t.
Senior ASP.NET Core Engineers
.NET 8, minimal APIs or controller-based, MediatR and CQRS when the domain earns it, EF Core with opinions about migrations, clean architecture patterns, Serilog or OpenTelemetry. Senior engineers with shipped ASP.NET Core at scale typically land in the $150K to $190K base range as of 2026, higher in major metros.
Azure-Forward .NET Engineers
App Service, Functions, Service Bus, Cosmos DB, Azure SQL, Event Grid, Key Vault, managed identities. Engineers who can design a real cloud architecture, not drop an IIS workload into a VM. Strong pairing with our cloud engineer staffing bench when the role crosses infra.
Full-Stack .NET + React / Angular
ASP.NET Core API on the back, React or Angular on the front, TypeScript all the way through. The hire most mid-market Microsoft shops actually want but write the JD poorly for. We staff these for SaaS, fintech, and healthcare product teams.
.NET Framework Maintenance
.NET Framework 4.x, classic MVC, WCF services, old Web Forms estate. Not glamorous, sometimes mission-critical. A narrow, deep bench of engineers who’d rather keep a 12-year-old payments platform running clean than chase the next shiny thing.
Migration Engineers (Framework to Core)
The hybrid hire. Comfortable in .NET Framework 4.8, fluent in .NET 8, and honest about what can and can’t be ported cleanly. Knows when to strangler-fig and when to rewrite. Pairs often with our DevOps staffing for the pipeline rebuild.
.NET Architects and Tech Leads
Domain-driven design without the dogma, event-driven patterns where they earn their keep, opinions about testing layers, real experience leading a 6-to-12 engineer team through a modernization. Direct hire only for these. Nobody builds this reputation in a 6-month contract.

[modern] Where Modern .NET Searches Land
Modern .NET has its own center of gravity. Three patterns cover most of what we staff.
Greenfield ASP.NET Core API work is the biggest bucket right now. A team’s spinning up a new service, picking minimal APIs or controller-based, deciding between MediatR and a simpler handler layer, arguing about whether to split the domain into verticals. The engineer needs real opinions, not a bullet-point resume. Wrong hire builds a toy architecture. Next hire rewrites it six months later, minus the parts the first hire broke.
Azure platform work is the second pattern. App Service and Functions as default compute, Service Bus for async, Cosmos DB or Azure SQL depending on data shape, managed identities everywhere, Bicep or Terraform for infra. Many of these crossover with our cloud engineer bench when the role leans more infra than app.
Modernization is the third. It’s the one most clients underestimate. Framework 4.8 monolith to .NET 8 services, on-prem SQL to Azure SQL, WCF to gRPC or REST, WinForms admin to Blazor. A senior engineer here doesn’t just write the new code. They call the port-versus-rewrite decision right. That alone can save six months.
[legacy] Where Legacy .NET Searches Land
Legacy .NET is older, and it still prints a lot of revenue for a lot of clients. The hires are steady, the urgency is rare, and the stakes quietly stay high because a seven-year-old WCF service running clean for 18 months doesn’t forgive a careless refactor.
Framework 4.x maintenance is the dominant shape. Old ASP.NET MVC, Web Forms that refuse to die, WCF services holding together between systems nobody wants to touch. The right hire isn’t a frustrated junior waiting to rewrite everything. It’s a senior who treats a working system with respect, makes small precise changes, and writes tests before shipping. We vet for that temperament explicitly.
Desktop .NET still ships. WinForms for internal tools, WPF for richer workflows, occasionally MAUI for a mobile rebuild. Manufacturing, healthcare records, government contractors, ERP integrators. These hires rarely show up on LinkedIn’s generic “.NET” searches because they’ve spent the last decade quietly maintaining the same kind of system for the same kind of client.
Migration engineers bridge the two tracks. Framework to Core. On-prem to Azure. Monolith to services. The honest ones tell clients when a rewrite is faster than a port, and they’ve been right often enough to get the next call.
How We Engage
Three models. Each fits a different shape of .NET work.
| Model | Best For | Typical Duration |
|---|---|---|
| Direct Hire | Permanent platform team, tech leads and architects, senior ASP.NET Core engineers | Permanent |
| Contract | Migration sprints, Framework maintenance capacity, Azure modernization, release surges | 3 to 12 months |
| Contract-to-Hire | Senior hires where fit matters, mid-level .NET engineers testing a new domain | 3 to 6 months, then convert |
| Project-Based | Fixed-scope modernization or greenfield build with a KORE1 team and named tech lead | Scoped per engagement |
Why KORE1 for .NET Staffing
We’ve placed engineers for 25 years. .NET isn’t a brochure line. It’s two specialties inside the IT bench. Our recruiters can tell the difference between a candidate who’s actually shipped ASP.NET Core at scale and one who added a few controllers to an existing Framework app. That distinction usually decides the search.
Every senior .NET candidate we submit clears a technical screen with an engineer on our panel. Modern candidates get a .NET 8 and Azure design question, often walked through a real system they built. Legacy candidates get a Framework tuning story, a WCF or MVC edge case, an honest look at how they handle maintenance work. Take-homes are optional and never unpaid. We tell candidates what to expect on the first call, which is part of why senior engineers actually return our follow-ups in a market where most agencies get ghosted.
We staff .NET nationally, with desks in Orange County, Los Angeles, and San Diego, plus remote placements coast to coast. Microsoft-stack work skews heavily to enterprise IT, finserv, healthcare, and gov contractors, so a lot of pipeline overlaps with our financial services IT, healthcare IT, and software engineering staffing work. For benchmarking comp before an offer goes out, teams use our salary benchmark tool to calibrate against current numbers.

Common Questions About .NET Staffing
How much does it cost to hire a .NET developer through a staffing agency in 2026?
Mid-level ASP.NET Core engineers with 3 to 5 years of experience land in the $125K to $155K base range as of early 2026. Senior engineers run $150K to $190K. Architects clear $180K. Bay area and NYC placements often go higher, sometimes $220K-plus on base alone. Contract rates for senior .NET engineers fall between $85 and $140 an hour, depending on the track and whether the engagement includes any on-call expectations. Anchoring a 2026 offer to 2022 numbers is the fastest way to lose a candidate in the final round.
.NET Framework vs .NET Core / .NET 8: what actually matters for hiring?
Cross-platform versus Windows-only, mainly. .NET Framework 4.8 is the last major Framework release. It runs on Windows only. .NET Core became .NET 5, then 6, 7, 8, and the annual cadence continues. Modern .NET runs on Linux, containers, Azure App Service, and cuts cold-start times for Functions dramatically. For new work, it’s .NET 8. For legacy, Framework 4.8 still ships. A team running both needs engineers who’ve actually shipped in both, not just one.
Can I hire a .NET developer specifically for Azure work?
Yes, and we’d recommend making that explicit in the JD. Our Azure-forward .NET bench is screened separately for App Service and Functions fluency, Cosmos DB versus Azure SQL trade-offs, Service Bus patterns, Bicep or Terraform comfort, and managed identity discipline. Trying to convert a generalist ASP.NET Core engineer into a cloud-architecture hire mid-engagement is the slow path. If the role is platform-heavy, we often steer the search through our cloud engineer staffing practice, which shares a panel with this one.
How long does a typical .NET developer search take?
Our average time-to-submit on .NET contract searches is 19 days. Direct hire searches for senior engineers run 4 to 7 weeks, architect searches 6 to 10. The honest pattern: searches close fastest when the hiring loop is two rounds instead of four, the JD picks one track (modern or legacy) instead of hedging, and the comp band is set against current market data. Everything else adds weeks.
Are .NET developers still in demand in 2026?
Yes, consistently so. C# stays in the top five most-used languages in the 2024 Stack Overflow Developer Survey, and the Microsoft-stack enterprise footprint hasn’t shrunk. Finserv, healthcare, government, manufacturing, and ERP integrators all run heavy .NET estates. The demand curve isn’t dramatic, it’s steady. Senior ASP.NET Core engineers with real Azure experience are the scarcest slice right now, and the comp reflects it.
Should I hire a full-time or contract .NET developer?
It depends on the work’s shape. If the project has a known endpoint under 12 months, a migration sprint, a release push, or a maintenance backlog, contract wins on math. No severance. No bench time. No recruiting overhead on the back end. If it’s the team you’re building for the next three years, direct hire wins. Contract-to-hire is the middle ground when fit matters more than speed. That’s common for architects and senior engineers joining a new domain.
Can .NET developers work remotely for our team?
Often, though less uniformly than Python or front-end work. Finserv and healthcare clients with regulated environments still push for hybrid or fully onsite. Modern ASP.NET Core product teams at SaaS and mid-market shops tend to stay remote-friendly. Our placements split roughly 55/45 remote versus hybrid across the .NET book. We shape the search to your in-office policy on the first call.
