File Extension Details
The CSX file extension represents a C# Script file, which is a specialized version of the standard C# source code file. Unlike traditional .cs files that must be part of a structured project and compiled into a Dynamic Link Library (DLL) or an Executable (EXE) before they can be run, CSX files are designed for direct execution. They utilize the Roslyn compiler's scripting engine, allowing the code to be interpreted and executed line-by-line or as a single script without a formal build process. This format is particularly useful for automation, administrative tasks, and rapid prototyping within the .NET ecosystem. CSX files support unique scripting directives such as '#r' for referencing external assemblies and '#load' for including other script files, which are not valid in standard C# source files. They are commonly used in Azure Functions, the C# Interactive window in Visual Studio, and with the 'dotnet-script' tool. By removing the need for boilerplate code like namespace and class declarations, CSX provides a lightweight, 'top-level' coding experience similar to Python or PowerShell, while maintaining the full power and type safety of the C# language.
