As already mentioned, yes, there is a huge difference between ASP and ASP.Net, that is why I asked you at the very start of your thread to clarify exactly what you are using.

Given that you are using .Net 4.0, in Visual Studio 2010, you should find the Chart Control directly in your toolbox, just drag and drop it onto your ASPX page.
