.NET Core Developers for Cloud-Native Builds and Framework Migrations

Teams usually come to Cortance for .NET Core developers at the same moment. A .NET Framework service has run untouched for six years, and someone tries to containerize it for a new Kubernetes cluster. IIS bindings, Framework-only NuGet packages and a hard-coded machine.config setting turn a two-week task into a two-month rewrite. Meanwhile, .NET 8 reaches end of support on November 10, 2026, so patching around the problem stops being an option soon. That is the point at which a team starts looking for .NET Core developers instead of another Framework workaround.

What changes when a service moves to Core

Core exists to solve this problem. It runs natively on Linux and Windows, ships as a self-contained executable that drops straight into a Docker image, and its Kestrel web server was built for containers from the start, not bolted onto IIS afterward. Side-by-side versioning lets a team run .NET 8 and newer LTS releases on the same host without the DLL conflicts that made Framework upgrades an all-or-nothing bet. For a cloud-native API or code that has to run the same way in a Linux pipeline and a Windows dev machine, Core is the framework built for the job, not adapted to it.

Recent work by Cortance .NET Core developers

1. Framework to Core migration. Bohdan Bo. moved a contract management application from .NET Framework to .NET Core and upgraded Entity Framework 6 to EF Core. He switched the data layer to asynchronous calls and covered the main workflows with BDD end-to-end tests.
2. Payment reconciliation and payouts automation. Denis M. built the system in C#, .NET Core, Entity Framework and Azure. It imports transactions from multiple payment providers, matches records across sources to catch discrepancies, and routes vendor payouts through an approval workflow.
3. Platform backend for a construction-tech SaaS. Yurii F. designed REST APIs in .NET Core for user provisioning, registration, authentication and license management across twenty-plus connected products, backed by RabbitMQ and Redis for messaging and caching.
4. Distributed ERP web app for e-commerce. Terence J. built ASP.NET Web API microservices, an MS SQL Server data layer and a Blazor frontend split across five modules for purchasing, warehousing, sales, shipping and reporting.

What a .NET Core hire usually works with

A .NET Core hire rarely works in isolation. Most engagements pair Core with ASP.NET Core for the API layer, EF Core for data access, and Azure or AWS for hosting, with Clean Architecture, DDD or CQRS for teams that need the codebase maintainable past the first release. Front-end work lands on Blazor when a team stays in C# end to end, or React when frontend and backend are owned by separate specialists. AI features increasingly land in existing .NET products too. On an enterprise audit platform, Bohdan Bo. built Azure Functions pipelines that suggest the most relevant next answer in an auditor's questionnaire, with checks that process each event exactly once.
