A C# developer is responsible for designing and building a mobile or desktop app from scratch. As we mentioned earlier, C# developers mostly work on the backend side of the development process. Still, they can also manage to work on the front end with the appropriate frameworks. Their role is also to update, maintain, and troubleshoot software applications.
Most C# developers must be familiar with the .Net framework. As a C# developer, you can create both Android and iOS-supported applications. You should have a deep understanding of object-oriented programming, and you should also be able to write re-usable C# code.
