About the technology

What .NET covers

.NET is a software platform for building web apps, APIs, cloud services, desktop tools, and background services. It is used with C#, ASP.NET Core, and related libraries to ship secure, maintainable systems for business software, commerce, and internal workflows.

Typical project work

  • Build ASP.NET Core applications and REST APIs
  • Modernise older .NET Framework systems
  • Connect SQL Server, Azure, and third-party services
  • Add authentication, logging, testing, and deployment support
  • Improve performance, reliability, and code structure

Skills that matter

Strong .NET specialists understand C#, object-oriented design, dependency injection, async code, and testing. They also know how to work with Entity Framework, NuGet packages, and CI/CD pipelines, so they can deliver code that is clean, stable, and easy to maintain.

When companies bring in help

Freelance .NET expertise is useful when a team needs extra hands for a release, a migration, or a hard-to-plan integration. It also helps when a project has legacy code, slow delivery, or a need for a specialist who can step in quickly without a long onboarding phase.

Dortmund project fit

In Dortmund, .NET work often supports industrial software, logistics, services, and internal business systems. Companies may want on-site input for workshops or architecture discussions, then remote delivery for implementation, testing, and support in English or German.

What good specialists deliver

Good .NET professionals write code that other experts can keep working on. They document decisions, handle edge cases, and align the solution with the current stack, whether that means .NET Framework, .NET, or ASP.NET Core. They focus on maintainability, not just getting features live.

Frequently asked questions

What clients ask us most about .NET — answered in short.

.NET is used to build web applications, APIs, desktop software, cloud services, and background jobs. Many companies also use it for internal tools, data-heavy business systems, and services that need strong structure and long-term maintainability. In practice, it often shows up with C#, ASP.NET Core, and SQL Server.

.NET is often chosen when teams want strong typing, good tooling, and a clear path for building business software. Compared with Java, it is usually valued for developer productivity and the Microsoft ecosystem; compared with Node.js, it is often preferred for larger back-end systems that benefit from structure. The best choice depends on the existing stack and the kind of system being built.

A strong .NET specialist usually also knows C#, ASP.NET Core, Entity Framework, SQL, and testing frameworks. Azure, authentication, API design, and CI/CD are common adjacent skills as well. For older systems, knowledge of .NET Framework and migration work is often important.

A .NET project needs more than syntax knowledge when the code base is real and the delivery is tied to business risk. Smaller tasks may only need a focused specialist, while migrations, architecture changes, or complex integrations benefit from deeper experience. The right level depends on how much legacy code, cloud work, or testing discipline is involved.

For many .NET projects, remote work is enough, especially for API work, refactoring, testing, and cloud delivery. In Dortmund, some companies still prefer on-site time for workshops, stakeholder alignment, or access to internal systems. A hybrid setup often works best when the project is both technical and business-critical.

A good .NET expert writes readable code, explains trade-offs clearly, and leaves the system easier to maintain. Look for evidence of testing, clean API design, solid error handling, and experience with the exact stack in use. Good specialists also ask about deployment, monitoring, and support, not just feature delivery.

Yes, .NET is still a strong choice for new systems, especially when the project needs performance, maintainability, and a mature toolset. ASP.NET Core is a common fit for modern web apps and APIs, while the wider ecosystem supports cloud and enterprise use cases. It is especially practical when the company already works with Microsoft technologies.

A careful .NET freelancer should ask about the current version, the deployment target, the database, and any legacy dependencies. It also helps to clarify testing expectations, release process, and whether the work is a greenfield build or a migration. These details make it easier to estimate risk and deliver the right solution.
