About the technology
C# at a glance
C# is a strongly typed, object-oriented language from Microsoft. It runs primarily on the .NET platform and supports web services, business applications, desktop software, games and cloud systems. Its mature tooling and broad libraries suit both new products and long-lived enterprise applications.
What C# builds
C# experts turn business requirements into maintainable software across many environments. Common deliverables include:
- ASP.NET Core APIs, web applications and background services
- Windows desktop applications with WPF or .NET MAUI
- Azure functions, integrations and event-driven services
- Unity games, simulations and interactive 3D experiences
Ecosystem and tooling
The C# ecosystem includes .NET, ASP.NET Core, Entity Framework Core, LINQ and NuGet packages. Professionals work with Visual Studio, JetBrains Rider, Git, Docker and CI/CD pipelines. They may also connect applications to SQL Server, PostgreSQL, message brokers and Azure services.
When specialists help
Companies bring in freelance C# expertise when delivery speed, architectural clarity or additional capacity matters. This is common during platform modernisation, API programmes, migrations from older .NET Framework applications, or integrations between business systems. In Stuttgart, specialists may support manufacturing, mobility, finance and technology teams while collaborating remotely or on site.
What strong professionals deliver
Experienced C# professionals separate domain logic from infrastructure, design clear interfaces and write code that remains testable as requirements change. They understand asynchronous programming, dependency injection, security, observability and performance. Strong specialists also document decisions and explain trade-offs to product, operations and business teams.
Choosing the right fit
Look for evidence that a specialist has delivered systems similar to yours, not only listed C# or .NET on a profile. Discuss the target runtime, deployment model, data access approach and testing strategy before work begins. Useful signs include thoughtful questions, focused code reviews and a practical plan for releases, monitoring and handover.
Frequently asked questions
Quick answers to the questions that come up most around C#.
C# is used for web applications, APIs, desktop software, cloud services, games and internal business systems. It is especially common where teams need a structured language, strong tooling and close integration with the .NET ecosystem.
C# and Java both support large, object-oriented applications and have mature enterprise ecosystems, while C# is closely integrated with .NET and Microsoft services. TypeScript is often preferred for browser interfaces, whereas C# commonly handles backend services, APIs and shared business logic.
A strong C# specialist may also work with ASP.NET Core, Entity Framework Core, SQL, REST, Docker and cloud services such as Azure. Knowledge of automated testing, CI/CD, messaging and application security is valuable for production systems.
The right level depends on the system’s complexity, risk and delivery stage rather than a fixed number of years. A small API may need focused .NET expertise, while a legacy migration or distributed platform benefits from someone who can assess architecture, testing, deployment and operational concerns.
Yes. C# work is well suited to remote collaboration through Git, issue tracking, code reviews and shared development environments. On-site sessions in Stuttgart can still help with domain workshops, legacy system access or close coordination with manufacturing and business teams.
C# with modern .NET and ASP.NET Core supports containerised services, serverless workloads, APIs and event-driven architectures. A specialist should be able to choose between a modular application and distributed services based on operational needs, not trend alone.
Review how the specialist explains design choices, testing boundaries, error handling and deployment risks. Strong C# work usually shows clear naming, focused abstractions, secure data access and code that can be monitored and maintained after handover.
C# is the programming language, while .NET is the runtime, framework and wider development ecosystem used to execute and support applications. A freelancer may therefore describe their expertise as C#, .NET or C Sharp, but the relevant skills should match the project’s framework version and deployment environment.
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.
