Directx Problem Wpf

[krizzmp 0]

i am having this problem with c# wpf directx

when i try to run this code vs says

{Prevalence of Main Window, which is defined in the assembly Wpf3DTest, Version = 1.0.0.0, Culture = neutral, PublicKeyToken = null, can not be created. Destination of an activation triggered an exception. There is an error in markup file MainWindow.xaml, line 1, position 9"}

(translated from danish using google translate)

it all works fine til i set the imagebrush

here i my xaml

<Window x:Class="Wpf3DTest.MainWindow"

any help will be apresiated (sorry for my bad spelling) i am planning on releasing the software here when im done, but bare over with me i am not that experienced as programmer as i am only 17.

thx in advance
