What a .cs file is

C# was designed at Microsoft in 2000 and is the main language for .NET applications and Unity game scripting. A .cs file is plain text compiled into an assembly (.dll or .exe) that the .NET runtime executes. Visual Studio is the traditional home, but VS Code with the C# extension works well on all three platforms and .NET itself is cross-platform.

Converting it

A .cs file is commonly converted to .dll, .exe or .txt. It is a plain text format, so any text editor can open and edit it directly.
