How can I achieve the same alpha border effect that can be seen in the new Visual Studio 2012 main window using windows forms? Its window seems to glow.

AFAIK you can do it with WPF using a mix of this chrome and a custom WPF border. Not sure if on WinForms you can, given it's limited styling options (compared with WPF). Anyway they are using WPF.

So I am not sure if it is the best method, but if you use Spy++ (32-bit) and you look in the windows, you can see that beneath Visual Studio's main window, you can see 4 "VisualStudioGlowWindow" objects.
I hooked the messages in Spy++, and as you could imagine, the 4 windows represent the 4 glowing borders around the form. Further inspection shows that these 4 "glow windows" implement the WS_EX_LAYERED Extended window style, so the glow itself isn't done in WPF (as far as I can tell.)!
Hopefully this clears some stuff up.

Unless you want to handle drawing the entire form yourself you cannot. Because Visual Studio 2010 and Visual Studio 2012 are written on top of WPF and used Windows not Forms.

Visual Studio 2012 draw its window border using native Win32 functions. It is not related to the WPF or WindowsForms -- you can do it with both.
The glow is rendered on a transparent window on top of the main window. The main window calls the DWM API to set the glass area to 0. This way you can draw over the original border and the system buttons. This is the correct way to do this.
You can look at code of WPF Shell (http://archive.msdn.microsoft.com/WPFShell) to see how the calls to DWM are made in order to remove the glass. The fact that its written to be compatible with WPF doesnt matter, because all you need is a handle (IntPtr) to the window.
If you have a WindowsForms codebase, don't migrate to WPF. WPF has not been improved in the latest .NET framework release and there are no roadmaps to improvements or new features as its team has been integrated into Windows 8 team.
