解决方案

我知道这是一个老问题，但我有完全相同今天同样的问题，我解决它使用

  ResizeMode =NoResize
  

而不是

  Allowstransparency =真
  

的

ResizeMode确实删除annoing边境太，不会影响WebBrowser控件。似乎是最简单的方法来解决你的问题在这种情况下：）

I am displaying a window with a WebBrowser control on it. I want the windows to be frameless so I have set WindowStyle="None" This works BUT displays a colored border around the window. Allowstransparency="true" removes this BUT the WebBrowser is no longer displayed (buttons are)

I have found http://www.neowin.net/forum/topic/646970-c%23-wpf-window-with-transparency-makes-windowsformshost-disappear/ BUT I cannot get it to work (SetWindowsLong Parameter error)

解决方案

I know this is an old question but I had exactly the same problem today and I solved it using

ResizeMode="NoResize"

instead of

Allowstransparency="true"

The ResizeMode does remove the annoing border too and does not impact the WebBrowser control. Seems to be the easiest way to solve your problem in this case :)
