I am using Win2000 with .net to develop a Windows forms System.  The
namespace of Windows forms i am using is System.WinForms.

    When i try to run it on win ME which install .net beta without the IDE,
i can't run it correctly.  After i change the namespace of Windows forms to
System.Windows.Forms, i can run it well.

    What i need to do (which namespace) to develop a program which can run
it well on Win200 and WinME?

The difference in namespace name has nothing to do with the OS.
WinForms was the name in beta 1 and earlier, but it was changed to
Windows.Forms as of beta 2, and that's the way it will stay.

Install a more recent version of .NET on your Windows 2000 machine,
and start using Windows.Forms everywhere.
