About the technology
What .NET Framework does
.NET Framework is Microsoft’s established software framework for building and running Windows applications and web services. It includes the Common Language Runtime, class libraries, and support for languages such as C# and Visual Basic. Many business-critical systems still depend on it, especially where stable Windows integration matters.
Typical systems
Companies use .NET Framework for internal business software, customer portals, APIs, desktop applications, and transaction-heavy enterprise systems. Common project work includes:
- Maintaining ASP.NET MVC and Web Forms applications
- Building Windows desktop software with Windows Forms or WPF
- Connecting services to SQL Server and enterprise databases
- Extending systems with secure APIs and background processes
Ecosystem and tooling
The ecosystem includes Visual Studio, NuGet, IIS, Entity Framework, ASP.NET, Windows Communication Foundation, and Microsoft SQL Server. Strong specialists understand configuration, dependency management, authentication, logging, testing, and deployment on Windows infrastructure. They can also work across C#, REST, XML, JavaScript, and Azure services where a legacy application meets newer systems.
When expertise matters
Companies bring in freelance professionals when a long-running application needs reliable maintenance, a migration must avoid business disruption, or internal capacity is limited. In Germany, .NET Framework often supports systems in manufacturing, finance, logistics, healthcare, and public administration. Remote collaboration works well when documentation and access are prepared; on-site work can help with protected infrastructure and complex releases.
Modernization paths
A specialist can assess whether a system should remain on .NET Framework, move selected services to modern .NET, or be replaced in stages. Useful work includes separating business logic, upgrading dependencies, introducing automated tests, improving observability, and creating migration boundaries. The right path depends on Windows dependencies, third-party components, compliance needs, and the expected lifetime of the application.
Signs of quality
Look for professionals who explain technical risk in business terms and can show ownership of comparable systems. Relevant evidence includes:
- Clear experience with ASP.NET, C#, IIS, and SQL Server
- Safe handling of legacy code and production releases
- Practical testing, debugging, and performance analysis
- A documented plan for maintenance or modernization
Good specialists also ask about deployment, security, support windows, and the people who will maintain the result after delivery.
Frequently asked questions
Before you brief your next project: the most common questions about .NET Framework.
.NET Framework is used to build and run Windows-based applications, enterprise web systems, APIs, desktop software, and background services. It is common in established business environments that rely on ASP.NET, IIS, SQL Server, or other Microsoft infrastructure.
.NET Framework is closely tied to Windows and contains many mature technologies used by existing enterprise systems. Modern .NET is cross-platform and generally better suited to new applications, but a full migration may be difficult when a system depends on Web Forms, WCF, Windows-only libraries, or older third-party components.
A strong .NET Framework specialist often works with C#, ASP.NET MVC or Web Forms, Entity Framework, SQL Server, IIS, REST APIs, and automated testing. Azure, authentication, JavaScript, CI/CD, logging, and application security are also valuable when the system connects to wider services.
The required depth depends on the system’s age, business importance, and technical risk. A maintenance task may need focused knowledge of ASP.NET and SQL Server, while a modernization or production-critical migration calls for a .NET Framework professional who can assess architecture, dependencies, testing, and release procedures.
Yes. .NET Framework work is often suitable for remote collaboration because source control, issue tracking, documentation, and secure development environments can be shared online. German companies should define access controls, meeting language, support hours, and any on-site requirements before work begins.
Keeping .NET Framework can be sensible when the application is stable, Windows-dependent, and supported by required libraries or vendor integrations. Migration is more attractive when the system needs cross-platform hosting, modern runtime features, simpler deployment, or a clearer long-term maintenance path.
Ask how the professional would inspect dependencies, reproduce defects, protect production data, and validate a release. A capable .NET Framework expert discusses trade-offs clearly, documents assumptions, and can explain how tests, monitoring, rollback plans, and security controls will reduce project risk.
.NET Framework projects may involve mature codebases, detailed domain rules, limited documentation, and strict release processes. Professionals should expect to investigate existing behavior carefully, communicate changes clearly, and balance modernization goals with the need to keep established business operations reliable.
The average hourly rate of freelancers in Germany who have used .NET Framework in their recent projects is 92 €, which corresponds to a daily rate of about 733 € based on an 8-hour working day.
Of the freelancers in Germany who have used .NET Framework in their recent projects, 82% hold at least a Bachelor's degree, 57% hold at least a Master's degree, and 9% hold a doctorate.
On average, freelancers in Germany who have used .NET Framework in their recent projects have 23 years of professional experience, with a single engagement typically lasting around 2 years.
The most common languages among freelancers in Germany who have used .NET Framework in their recent projects are German (100%), English (95%), and Russian (17%).
The most common industries among freelancers in Germany who have used .NET Framework in their recent projects are Information Technology (95%), Manufacturing (55%), and Automotive (50%).
The most common business areas among freelancers in Germany who have used .NET Framework in their recent projects are Information Technology (98%), Product Development (92%), and Quality Assurance (57%).
