About the technology
What .NET Core does
.NET Core is Microsoft’s cross-platform framework for building web applications, APIs, background services and cloud-native systems. Its successor, modern .NET, extends the same ecosystem across Windows, Linux and macOS. Teams use it when performance, maintainability and integration with Microsoft services matter.
Where it fits
- ASP.NET Core applications and REST APIs
- Microservices and background processing
- Enterprise portals and internal business systems
- Cloud workloads deployed to Azure, containers or Kubernetes
The technology supports both greenfield products and the modernization of older .NET Framework applications. It can connect user interfaces, data services and external systems behind well-structured APIs.
Ecosystem and tooling
.NET Core work commonly includes C#, ASP.NET Core, Entity Framework Core, LINQ and dependency injection. Strong specialists also use NuGet, Visual Studio or JetBrains Rider, Git, Docker and automated test frameworks. Depending on the system, they may work with SQL Server, PostgreSQL, Redis, message brokers and Azure services.
When companies need expertise
Companies often bring in freelance expertise when an API must scale, an application needs migration from .NET Framework, or a delivery team lacks specialist capacity. In Frankfurt, professionals may support local product teams, financial services, logistics operations and industrial businesses while collaborating remotely or on site. Clear English is common; German can help when requirements and stakeholders are local.
Delivery responsibilities
A .NET Core specialist can shape service boundaries, implement secure endpoints, model data and integrate identity providers. Typical deliverables include tested APIs, database migrations, deployment pipelines, container configurations and technical documentation. They should also be comfortable reviewing existing code, diagnosing production issues and communicating trade-offs to the wider team.
What strong professionals bring
Look for evidence of production systems rather than framework familiarity alone. Strong professionals explain why they choose a hosting model, how they handle authentication, validation, resilience and observability, and where asynchronous processing is useful. They write maintainable C# and tests, understand performance bottlenecks, and can work within an existing architecture without creating unnecessary complexity.
Frequently asked questions
Key details about .NET Core, drawn from the questions we get asked most.
.NET Core is used to build cross-platform web applications, REST APIs, background services, microservices and enterprise systems. It is especially useful when a company needs a Microsoft-supported stack that can run on Windows, Linux, containers or cloud infrastructure.
.NET Core was designed as a modern, cross-platform alternative to the Windows-focused .NET Framework. It offers a modular runtime, strong container support and a current path through modern .NET, while .NET Framework may still be relevant for older applications tied to Windows-specific libraries.
.NET Core projects often require C#, ASP.NET Core, Entity Framework Core, SQL, REST, authentication and automated testing. Depending on the assignment, useful adjacent skills include Docker, Kubernetes, Azure, CI/CD pipelines, message brokers and frontend integration.
.NET Core experience should match the system’s risk and complexity rather than a fixed tenure. A simple API may need solid framework knowledge, while a regulated enterprise platform or migration calls for a professional who has handled architecture, security, deployment and production support in comparable systems.
.NET Core work is well suited to remote collaboration because source control, issue tracking, testing and cloud environments can be shared online. Frankfurt companies should define overlap hours, documentation standards and communication language clearly, then decide whether workshops or sensitive delivery phases require on-site work.
.NET Core can be a strong choice when the team already uses C#, Microsoft identity, Azure or established .NET libraries. Node.js may suit JavaScript-heavy teams and event-driven services, while Java remains common for large enterprise ecosystems; the right decision depends on existing skills, integrations and operational needs.
Ask a .NET Core professional to explain a relevant system they delivered, including API design, data access, testing, security and deployment. Review code samples or a technical discussion for clear boundaries, sensible error handling, observability and decisions that fit the stated constraints.
.NET Core remains relevant through its evolution into modern .NET, which continues the cross-platform runtime and ASP.NET Core ecosystem. For a new application, confirm the supported .NET version, library compatibility, hosting model and upgrade path before work begins.
The average hourly rate of freelancers in Frankfurt, Germany who have used .NET Core in their recent projects is 99 €, which corresponds to a daily rate of about 792 € based on an 8-hour working day.
