About the technology
What .NET covers
.NET is Microsoft’s open-source platform for building web applications, APIs, background services, desktop software and cloud systems. It supports C# as its primary language and combines a common runtime, standard libraries, project tools and a broad ecosystem. Teams use it for new products as well as long-running business applications.
Products and workloads
.NET fits projects where reliability, integration and maintainable code matter:
- ASP.NET Core applications and REST or gRPC APIs
- Enterprise services connected to databases and messaging systems
- Blazor interfaces and shared C# web experiences
- Windows desktop software with WPF or Windows Forms
- Cloud-native workloads running on Azure, containers or Kubernetes
Its flexibility makes it suitable for internal systems, customer portals, logistics software, financial services and industrial applications.
Ecosystem and tooling
Strong .NET professionals work across C#, the .NET SDK, NuGet and Entity Framework Core. They may also use ASP.NET Core, Blazor, LINQ, SignalR and message brokers such as Azure Service Bus. Practical delivery often includes SQL databases, REST contracts, Docker, Kubernetes, Azure DevOps or GitHub Actions, logging and automated testing.
When companies need specialists
Companies often bring in freelance expertise when a .NET system needs a clear technical direction or extra delivery capacity:
- Replacing older .NET Framework components with modern .NET
- Designing APIs, service boundaries or integration layers
- Improving performance, security, deployment or test coverage
- Connecting business software with Azure, ERP, CRM or data platforms
- Supporting a product team during a migration or release phase
For teams in Dortmund, remote collaboration can widen access to suitable specialists while on-site workshops remain useful for complex domain discovery.
What strong professionals bring
A capable .NET specialist understands more than syntax. They clarify domain rules, choose an appropriate architecture and make trade-offs visible. They can explain why a modular monolith, distributed services or a simpler application fits the situation. They also consider authentication, authorization, data consistency, observability and long-term maintenance from the start.
How quality becomes visible
Look for evidence of production work with systems similar in scale, integration needs and operational constraints. Useful examples include clean API contracts, migration plans, automated tests, deployment pipelines and decisions that improved maintainability. Strong professionals ask about users, data, failure handling and ownership before proposing a framework. Clear documentation and communication in English or German can support effective collaboration with teams in Dortmund.
Frequently asked questions
What clients ask us most about .NET — answered in short.
.NET is used for web applications, APIs, background services, desktop software, cloud workloads and integration systems. Companies choose it for customer portals, internal operations, financial workflows, industrial software and business platforms that need strong Microsoft ecosystem support.
.NET and Java both suit structured enterprise systems, with mature tooling, strong type systems and broad cloud support. Node.js can be a natural fit for highly JavaScript-centric teams or lightweight event-driven services. The right choice depends on existing skills, hosting, integration needs and the system’s operational demands.
A strong .NET expert often brings C#, SQL, HTTP, REST, authentication and automated testing skills. Experience with Azure, Docker, Kubernetes, CI/CD pipelines, observability and message-based integration is valuable when the work extends beyond a single application.
The required level depends on the scope, risk and existing team. A contained API enhancement may need focused implementation experience, while a migration, high-availability service or complex integration benefits from a professional who has owned architecture, release processes and production support.
.NET work is well suited to remote collaboration through Git, issue tracking, documentation, code reviews and shared development environments. For teams in Dortmund, occasional on-site workshops can help with domain knowledge and architecture, while day-to-day delivery can remain remote. English is common, and German may matter for local stakeholders.
Modern .NET is generally preferred for new cross-platform applications, containers and current cloud deployments. .NET Framework may still be appropriate when an existing Windows application depends on legacy libraries or platform-specific behavior. A specialist should assess migration effort, business risk and support requirements before recommending a path.
Ask how the professional approaches architecture, testing, security, deployment and failure handling, not only which libraries they know. Review relevant production examples, technical decisions and documentation. A quality .NET specialist explains trade-offs clearly and connects implementation choices to business requirements.
.NET is the current unified platform for building applications with C# and other supported languages. .NET Core was the earlier cross-platform line that led into modern .NET, while ASP.NET Core is the web framework used for applications and APIs on that platform. Microsoft .NET is also a common name for the wider ecosystem.
