About the technology
What C# is used for
C# is a statically typed programming language from Microsoft and the main language of the .NET ecosystem. Companies use it for web APIs, enterprise platforms, desktop applications, cloud services, games with Unity and services that process business-critical data. Its strong tooling and broad runtime support make it suitable for both new products and long-lived systems.
Core ecosystem
C# work commonly spans .NET, ASP.NET Core, Entity Framework Core and LINQ. Professionals may also use Azure Functions, Blazor, SignalR, SQL Server, Docker and Kubernetes, depending on the system. Visual Studio, JetBrains Rider, GitHub Actions and Azure DevOps support coding, testing, deployment and maintenance across the delivery cycle.
Typical project work
- Design and extend ASP.NET Core APIs and backend services
- Modernize .NET Framework applications for current .NET
- Connect business systems to SQL Server, Azure and external APIs
- Build internal tools, desktop software or Blazor interfaces
- Develop Unity features and supporting game services
Strong C# specialists understand more than syntax. They choose suitable abstractions, structure domain logic, handle asynchronous operations and create tests that protect important behavior. They also know how runtime, database and deployment decisions affect the complete application.
When companies need experts
Companies often bring in freelance C# expertise when a product team must extend an existing .NET codebase, replace older .NET Framework components or deliver an API under a fixed release plan. A specialist can clarify architecture, remove bottlenecks, improve test coverage or provide capacity during a migration. In Switzerland, remote collaboration may work well when documentation and communication are clear; some projects still require on-site workshops for regulated or operational systems.
Skills around C#
Useful adjacent skills include REST and gRPC API design, relational database modelling, authentication, messaging and frontend integration. Depending on the project, companies may need experience with Azure, AWS, CI/CD, observability, Terraform or event-driven architecture. Familiarity with German, French, Italian or English can matter when specialists work with Swiss stakeholders, distributed teams or local documentation.
What distinguishes strong professionals
Look for evidence of ownership across design, implementation, testing and production support. Strong professionals explain why they choose a .NET version, data-access approach or hosting model instead of relying on familiar patterns alone. They review existing code carefully, communicate trade-offs in plain language and leave behind maintainable tests, documentation and deployment practices. Experience with the relevant domain matters as much as knowledge of C# itself.
Frequently asked questions
Everything clients usually want to know about C#, in one place.
Companies use C# for ASP.NET Core APIs, enterprise applications, cloud services, desktop software and Unity games. It is also common in systems that combine business workflows, databases, authentication and integrations with Microsoft services.
C# and Java both support large, strongly typed application backends and have mature enterprise ecosystems. TypeScript is often preferred for browser-facing code, while C# can cover backend, desktop, cloud and game development through .NET and related tooling.
A strong C# specialist may also work with ASP.NET Core, Entity Framework Core, SQL Server, Azure, Docker and CI/CD pipelines. API design, automated testing, security, messaging and frontend integration are often important for the complete project.
The right level depends on the system’s scope, age and risk. A small API extension may need focused knowledge of C# and the existing .NET codebase, while a migration or distributed platform requires architecture, testing, deployment and production-support experience.
Yes, many C# projects work well remotely when repositories, environments and technical decisions are documented. On-site workshops can still help with regulated systems, complex stakeholder alignment or access to company infrastructure in Switzerland.
Ask how the expert approaches an unfamiliar codebase, testing strategy, database access and failure handling. A capable C# professional explains trade-offs clearly, demonstrates maintainable code and can connect implementation choices to reliability, security and business needs.
C# is well suited to cloud applications through modern .NET, ASP.NET Core, Azure services, containers and serverless options. The language supports asynchronous processing, observability and service integration, but the system still needs sound cloud architecture and operational practices.
Freelancers working with C# should expect projects across current .NET and older .NET Framework systems. They may need to use Visual Studio or Rider, understand NuGet dependencies, work with Entity Framework Core and adapt to team practices for testing, version control and deployment.
The average hourly rate of freelancers in Switzerland who have used C# in their recent projects is 125 €, which corresponds to a daily rate of about 1,000 € based on an 8-hour working day.
Of the freelancers in Switzerland who have used C# in their recent projects, 85% hold at least a Bachelor's degree, 60% hold at least a Master's degree, and 5% hold a doctorate.
On average, freelancers in Switzerland who have used C# in their recent projects have 22 years of professional experience, with a single engagement typically lasting around 2.6 years.
The most common languages among freelancers in Switzerland who have used C# in their recent projects are German (100%), English (96%), and French (32%).
