What is a .CS file?
CS files are source code files written in C#, a programming language developed by Microsoft for building Windows applications, web services, games, and other software. They are widely used with the .NET platform and contain human-readable instructions that define how a program works, including its features, user interface, data processing, and interactions with other components.
You may come across CS files when browsing the source code of a .NET application, working on a C# software project, or downloading an open-source program from a code repository. They are often stored alongside project files, libraries, configuration files, and other source code, and a project may contain many CS files for different parts of the application. File Viewer Plus can open, edit, and save CS files, making it convenient to view and modify C# source code.
