Hi, I'm trying to place a WindowsFormsHost in a ContentPane, but I'm experiencing problems when trying to resize the SplitPane that contains it all. Please take a look at my sample. If you run the sample, the panes are all empty and you will notice that the panes can be resized without any problems. Now, if you uncomment the WindowsFormsHost in the XAML and run the sample again, the application will crash when you try to resize a splitpane. The exception is an InvalidOperationException saying "Specified element is already the logical child of another element. Disconnect it first.". What am I doing wrong?

Regards, Stefan
