About the technology
What .NET covers
.NET is Microsoft’s open-source platform for building web applications, APIs, desktop software, background services and cloud-native systems. The ecosystem includes modern .NET, the C# language, ASP.NET Core and the wider tooling used to run business-critical applications across Windows, Linux and containers.
Where it is used
.NET supports software that needs clear structure, strong security and reliable integration with existing systems.
- Customer portals and internal business applications
- REST APIs, microservices and event-driven services
- Desktop applications with WPF or .NET MAUI
- Cloud workloads on Microsoft Azure
- Data-heavy systems connected to SQL Server and other databases
Ecosystem and tooling
Strong specialists work across C#, ASP.NET Core, Entity Framework Core and dependency injection. They use Visual Studio or JetBrains Rider, NuGet packages, Git, automated testing and continuous delivery pipelines. Azure Functions, Azure App Service, Docker and Kubernetes often form part of the delivery environment.
When companies bring in specialists
Freelance expertise helps when an existing application needs modernization, an API must connect several systems or a team is moving from .NET Framework to current .NET. It is also valuable for performance work, secure authentication, test automation and cloud migration. Companies in Dortmund may choose on-site collaboration for workshops while keeping implementation remote.
- Replace legacy .NET Framework components
- Design service boundaries and integration APIs
- Improve deployment, observability and resilience
- Establish testing and code review practices
What strong professionals deliver
Experienced .NET professionals translate business processes into maintainable software. They make sensible choices between a modular monolith, microservices and serverless services instead of forcing one pattern everywhere. Their work includes readable C# code, documented interfaces, automated tests, secure identity flows and deployment instructions.
Choosing the right fit
Look for specialists whose portfolio matches your runtime, application type and hosting model. Ask how they handle migrations, database changes, failure recovery and production monitoring. For teams in Dortmund, clarify German and English communication needs, workshop expectations and the balance between remote and on-site work before delivery begins.
Frequently asked questions
What clients ask us most about .NET — answered in short.
.NET is used for web applications, REST APIs, desktop software, background services and cloud systems. Its libraries and tooling also support integrations, data access, authentication and automated testing.
.NET offers a strongly typed ecosystem centred on C# and integrates closely with Microsoft services, while Java has a similarly broad enterprise focus and Node.js uses JavaScript on the server. The right choice depends on the existing team, runtime requirements, hosting environment and available libraries.
A strong .NET specialist often also works with SQL databases, REST and messaging, Git workflows, Docker, automated testing and cloud deployment. Experience with Azure, identity standards, observability and CI/CD is useful for production systems.
The required depth depends on the system’s risk and scope. A professional modernising a legacy .NET Framework application should understand migration constraints, while someone shaping a new API should show sound architecture, security and deployment decisions in comparable projects.
.NET work is well suited to remote collaboration because source control, issue tracking, testing and deployment can be handled online. Dortmund-based teams may still prefer on-site workshops for discovery, architecture decisions or collaboration with stakeholders.
.NET is generally the better foundation for new cross-platform services, containers and current cloud environments. .NET Framework remains relevant for established Windows applications that depend on older libraries or platform-specific features.
Ask for concrete examples of shipped .NET systems and discuss the decisions behind their architecture. Review how they approach testing, security, database changes, monitoring, code readability and handover rather than judging experience by framework names alone.
A .NET project may involve C#, ASP.NET Core, Entity Framework Core, Azure or legacy .NET Framework components at the same time. Clarify the target runtime, build pipeline, coding standards, deployment ownership and communication language before committing to the work.
