C# (pronounced "c sharp") is a computer language used to create applications that allow a person to interact with the machine. This site provides lessons and topics on how to use that language. Because C# is not a programming environment, all lessons here are taught with the language in mind. All applications are compiled at the Command Prompt.

We have released our "C# Fundamentals" ebook. It contains updated material with step-by-step instructions and Practical Learning examples.
