About the technology
What C# is
C# is a strongly typed, object-oriented programming language from Microsoft. It runs primarily on the .NET platform and supports web, desktop, mobile, cloud and game software. Its language features, tooling and broad library ecosystem suit both business applications and complex technical products.
What it builds
C# specialists deliver software across many environments:
- ASP.NET Core websites, backend services and REST APIs
- Enterprise applications with business rules, workflows and integrations
- Windows desktop software with WPF or Windows Forms
- Cross-platform applications with .NET MAUI
- Games and interactive experiences with Unity
C# also appears in automation tools, data-processing services and internal systems that connect to Microsoft technologies.
Ecosystem and tooling
The ecosystem includes .NET, ASP.NET Core, Entity Framework Core, NuGet and Visual Studio. Strong professionals work with SQL Server, Azure, Docker, Git and continuous integration pipelines. They may also use xUnit, NUnit or other testing tools, along with message brokers, REST clients and observability services.
When companies bring in specialists
Companies often seek freelance C# expertise when a product needs a new API, a legacy .NET application needs modernisation or an internal system must connect with cloud services. Specialist support is also useful for:
- Designing service boundaries and integration patterns
- Migrating older .NET Framework software to current .NET
- Improving performance, security and test coverage
- Extending teams during a delivery or platform transition
In Stuttgart, this work can support manufacturing, mobility, engineering and enterprise software environments, with collaboration arranged on-site, remotely or in a hybrid model.
Skills that matter
A capable C# professional understands language design, asynchronous programming, dependency injection and reliable error handling. They can model data, secure APIs, write maintainable tests and diagnose production issues. Experience with deployment, monitoring and code review matters as much as writing application logic.
Choosing the right professional
Assess specialists through relevant deliverables rather than language familiarity alone. Ask how they approach architecture, testing, upgrades and integration with existing systems. For remote collaboration, clarify documentation habits, working hours and communication in English or German. The right professional explains trade-offs clearly and leaves code that the internal team can operate and extend.
Frequently asked questions
Quick answers to the questions that come up most around C#.
C# is used for web applications, APIs, enterprise systems, desktop software, cloud services and games. Its close integration with .NET makes it practical for products that need structured code, Microsoft integrations and long-term maintainability.
C# and Java both support strongly typed, object-oriented applications and large enterprise systems. C# has particularly deep ties to .NET, Azure, Visual Studio and Microsoft services, while Java is widely used across many vendor-neutral and JVM-based environments.
A strong C# specialist often works with .NET, ASP.NET Core, Entity Framework Core, SQL databases, REST APIs and automated testing. Cloud deployment, Docker, Git, CI pipelines and security knowledge are valuable when the work extends beyond application code.
The right C# freelancer should show work comparable to your system, such as an API platform, a desktop product, a cloud service or a legacy migration. The required depth depends on architecture, risk and integration complexity, so review concrete deliverables and technical decisions rather than relying on language familiarity.
C# projects are often suitable for remote or hybrid collaboration because source control, issue tracking, testing and deployment can be handled online. Stuttgart-based teams should still define overlap hours, access requirements and whether German-language communication is needed for business or production stakeholders.
Review how the C# specialist structures code, handles failures, protects data and tests important paths. Ask for examples of monitoring, documentation, code review and technical trade-offs, then use a focused technical discussion to confirm that the approach fits your architecture.
C# is well suited to cloud applications through .NET, ASP.NET Core and integrations with Azure and other infrastructure. Specialists can build containerised services, background workers and APIs, but should also understand deployment automation, observability, scaling and cloud security.
A C# professional working on older .NET systems should be able to understand framework constraints, dependency issues and tightly coupled application logic. They should propose a controlled upgrade or modernisation path, protect existing behaviour with tests and separate urgent fixes from longer-term redesign.
The average hourly rate of freelancers in Stuttgart, Germany who have used C# in their recent projects is 97 €, which corresponds to a daily rate of about 776 € based on an 8-hour working day.
