Hi there,

Anyway, to cut to the chase -- C# is one of microsoft's Visual .NET languages -- so, Microsoft Visual C# .NET to use its full name. That said, C# & C#.NET are the same thing -- there are a few versions of them (depending on which version of .NET we are talking about) two of the most prominent being version 1.1 and version 2.0 (the current release). That said, as far as I know, there is no divorce between the two nomenclatures -- so if someone tells you C# is different to C#.NET -- you should really ask them 'why' they believe that :)

That said, here is the C# language reference from the MSDN. It can provide useful insights into the language, but I only put it here because it is a curiosity you might find interesting.
