About the technology

What .NET Core does

.NET Core is Microsoft’s cross-platform framework for building modern web applications, APIs, background services and cloud software. It runs on Windows, Linux and macOS, making it suitable for distributed systems and teams with varied infrastructure. The technology is now part of the unified .NET platform, while .NET Core remains a common search term for earlier and current project requirements.

Core ecosystem

Professionals working with .NET Core typically use C#, ASP.NET Core, Entity Framework Core and the built-in dependency injection system. They may also work with SQL Server, PostgreSQL, REST, gRPC, Docker, Kubernetes and Azure services. Strong knowledge of Visual Studio, JetBrains Rider, NuGet, Git and automated testing supports reliable delivery.

Typical project work

  • Design REST APIs and microservices with ASP.NET Core
  • Build secure web applications and internal business systems
  • Connect services to relational and cloud databases
  • Containerize applications for cloud or hybrid deployment
  • Modernize older .NET Framework applications

.NET Core specialists also create message-driven services, identity integrations and scheduled processing jobs. They can establish the application structure, implement features and prepare deployment pipelines for continued development.

When companies need specialists

Freelance expertise is useful when a team is moving from .NET Framework to cross-platform .NET, replacing a monolith or preparing a service for higher operational demands. It also helps when an internal team needs focused support for an API, cloud migration or release process.

  • Existing services are difficult to test or deploy
  • A new product needs a stable backend foundation
  • Azure, containers or service integration require specialist knowledge
  • Delivery is blocked by unfamiliar Microsoft tooling

What strong professionals bring

Good .NET Core professionals make clear architectural choices rather than adding complexity by default. They understand asynchronous programming, dependency injection, configuration, observability, authentication and secure API design. They write maintainable C# and use unit, integration and contract tests where those tests add practical value.

They also communicate trade-offs clearly. A strong specialist can work with product teams, infrastructure professionals and existing code owners, document decisions and leave a system that others can operate.

Working with Dortmund teams

Companies in Dortmund may use .NET Core for industrial software, logistics systems, commerce applications, energy services and internal enterprise platforms. Local specialists can support workshops or on-site collaboration, while remote professionals can contribute through shared repositories, planning sessions and documented handovers.

For successful collaboration, agree on the target .NET version, hosting model, security responsibilities and delivery scope early. German or English communication can work well when technical decisions, acceptance criteria and operational ownership are recorded clearly.

Frequently asked questions

The facts hiring teams ask for most often when it comes to .NET Core.

.NET Core is used to build web applications, REST APIs, background services, microservices and cloud software. Its cross-platform runtime lets teams deploy applications on Windows or Linux and connect them to databases, queues and external services.

.NET Core was designed as a modern, cross-platform alternative to the Windows-focused .NET Framework. Current projects generally use the unified .NET platform, while .NET Framework remains relevant for older applications that depend on Windows-specific libraries.

A capable .NET Core specialist often brings C#, ASP.NET Core, Entity Framework Core, SQL, REST and automated testing skills. Depending on the project, experience with Azure, Docker, Kubernetes, message brokers, identity standards and CI/CD is also valuable.

The right .NET Core freelancer depends on the system’s risk and scope, not a fixed experience threshold. A smaller API may need focused framework knowledge, while a regulated or distributed system calls for proven architecture, security, testing and production operations skills.

Yes. .NET Core work is well suited to remote collaboration because source code, tests, infrastructure definitions and deployment pipelines can be reviewed online. Dortmund teams should define meeting routines, documentation standards and language expectations so remote and on-site contributors stay aligned.

ASP.NET Core is a strong choice when a company needs a maintainable API or web service with good performance, structured dependency injection and broad hosting options. It fits especially well when the team already uses C#, Microsoft tooling or Azure, but the choice should still reflect operating and integration requirements.

Review how the .NET Core professional explains architecture, error handling, security, testing and deployment. Ask for examples of trade-offs, inspect a small technical task or code sample, and confirm that the specialist can improve maintainability rather than only deliver isolated features.

Before engaging a .NET Core freelancer, clarify the target .NET version, application boundaries, hosting environment, data stores and authentication approach. Also define ownership of infrastructure, test coverage, monitoring, documentation and handover so delivery expectations are clear.
