Difference between c# and c#.net!?

Question

Hi I have been asked by my boss to larn the basics of c#.net. I am not from a programming background and was wondering if there is a difference between c# and c#.net, or are they the same thing? I have downloaded Microsoft Visual C# 2005 Express Edition, and am learning from videos I've downloaded from the web - can anyone recommend good video tutorials for a beginner? Thanks Al
