Hire .NET Developers for Multi-Tenant SaaS Platforms

Cortance matches .NET engineers who work across the stack a .NET product runs on, from C# and ASP.NET Core to Blazor, Entity Framework Core and SQL Server. Of the 24 .NET profiles in our network in September 2026, 17 are senior and 17 are based in Europe.

That range is rarer than it sounds. Stack Overflow's 2025 Developer Survey found that 29.9 percent of professional developers do extensive work in C#, while only 21.3 percent touch ASP.NET Core and 15 percent work with classic ASP.NET. A developer who knows one .NET framework covers a fraction of what most .NET teams need built. Share your requirements, and a matched .NET engineer can onboard in about 2 days.

Where a .NET Generalist Fits (and Where It Doesn't)

This page covers engineers who work across the .NET ecosystem: C#, ASP.NET Core, Blazor, Entity Framework Core, LINQ, SQL Server, Azure, AWS, and desktop frameworks like WPF, WinForms, and .NET MAUI. That is the right fit when a project needs one engineer, or a small team, to own a Blazor frontend, a Web API backend, and the SQL Server layer underneath it. The alternative is three separate specialist hires who barely talk to each other.

If your work sits entirely in one layer, a narrower page usually gets you a closer match faster. Teams maintaining a pure legacy codebase with no modernization plan should see our .NET Framework developers page. Teams that already know they need ASP.NET Core web APIs specifically, and nothing else, are better served by the ASP.NET developers page. The same logic applies if your gap is strictly ADO.NET-level data access work or a .NET Core only backend: those are separate, narrower pages for a reason.

Three .NET systems our engineers built end to end

1. Multi-tenant SaaS platform. Pedro S. built APIs and full-stack features in .NET 8, ASP.NET Core, Entity Framework Core, and Blazor, with Azure App Service, SQL Database, and Key Vault handling the infrastructure layer.
2. Cloud sensor monitoring system. Delivered real-time device monitoring, configuration, and diagnostics across ASP.NET Core and Blazor, with Azure hosting and MS SQL Server underneath.
3. Subscription billing platform. Denis M. built the backend of a self-service billing portal in C#, ASP.NET, Entity Framework, and SQL Server, with proration, refunds, and webhook-driven invoice generation.

AI tooling changes .NET migration work more than new builds. On a .NET Framework 4 to .NET 6 upgrade like the one Ivan S. ran for a multi-building concierge platform, an assistant can draft the repetitive changes to project files, package references and async signatures. It cannot decide where tenant boundaries sit or which legacy behaviour residents and staff still depend on, so the engineer keeps those calls. Two of our 24 .NET engineers, Ivan S. and Yaroslav R., list Claude Code among their .NET tools.

Six Layers, One .NET Team

A single Cortance .NET hire, or a small dedicated team, typically covers: C# as the core language, ASP.NET Core and Blazor for web and UI, Entity Framework Core and LINQ for data access, SQL Server for the database itself, and Azure or AWS for hosting and cloud services. Several also bring WPF, WinForms, or .NET MAUI when a project still has a desktop or cross-platform client to maintain. When a project needs more depth in just one of those layers, we pair the generalist with a dedicated Azure or SQL Server specialist rather than stretching one person thin.

Which .NET layers does your project touch?

Tell Cortance which layers your project touches, backend, frontend, data or all three, and we will send matched .NET profiles. Assemble a dedicated team for long-term platform ownership, bring in a single senior engineer to unblock a specific system, or add staff augmentation for a release crunch. A matched engineer can onboard in about 2 days.
