Wpf WindowsFormsHost is not displayed when AllowsTransparency = "True"

someone touched this issue here http://social.msdn.microsoft.com/forums/en-US/wpf/thread/6f9dd3b5-af92-4076-9b4e-1a770dd52f70/

but that was in 2006. I am currently using .net framework 3.5. Is there a better solution for this now. Does anyone know if Microsoft has a direct solution for this problem in 4.0?
