Opening CS files

Did your computer fail to open a CS file? We explain what CS files are and recommend software that we know can open or convert your CS files.

What is a CS file?

Files that contain the .cs file extension are files that contain source code. The source code in a .cs file has been written in the C# or C# .NET programming language.

C# is a programming language that is used to create a variety of .NET Framework applications. It is commonly created with the Microsoft Visual C# toolset. This toolset can be used to create XML services for .NET connected applications. The CS files are usually compiled by a csc.exe file.

The types of source code code that a CS file can contain may include source code for console applications, library files and GUI applications.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
