Makes sense, but see also my comment below. Would you post this link as a formal answer? It would make some reasonable answer/advice.

It looks like people feel tired of those slanted borders and windows shadows. Creating a custom shadow is not the simplest task. A very simple shadow can be rendered as a semi-transparent shape, but standard Windows shadow is a bit better: it also uses some blur, which is harder to render and can even compromise performace. And yet, good designers keep blaming developers of such shadows for their artificial and primitive look. So, why going int this struggle at all? Those shadows won't give you really pleasant or impressive look anyway... Just think about it.

[EDIT] And if you want to enable standard shadows, use the advice by DotNetSteve above.

In WinForms, you can just override the form's protected CreateParams property and add the CS_DROPSHADOW flag to the class styles. For example:

C#
public class ShadowedForm : Form {
    protected override CreateParams CreateParams {
        get {
            const int CS_DROPSHADOW = 0x20000;
            CreateParams cp = base.CreateParams;
            cp.ClassStyle |= CS_DROPSHADOW;
            return cp;
        }
    }

    // ... other code ...
}



1. This flag works only on top-level windows. In Win32-speak, that means overlapped and popup windows. It has no effect on child windows (e.g. controls). I thought I remembered hearing somewhere that this limitation had been removed from Windows 8, but I can't find a link confirming this and I don't have Windows 8 installed for testing purposes.

2. It is possible that the user has disabled this feature altogether. If so, you won't get drop shadows, no matter how you ask for them. That's by design. Your application should not try and override this request. You can determine whether drop shadows are enabled or disabled by P/Invoking the SystemParametersInfo function and passing the SPI_GETDROPSHADOW flag.

3. The Aero theme also adds shadows to top-level windows. This effect is separate and distinct from CS_DROPSHADOW, and works only when Aero is enabled. Theres no way to turn it off and on for individual windows. Moreover, since the Aero theme has been removed from Windows 8, it won't ever have these shadows.
