I am trying to host the WPF RichTextBox is my WinForm but I am having this issue when resizing the form.

Add an ElementHost control to a WinForm, anchor to all sides of the form, add a new System.Windows.Controls.RichTextBox as the child for the elementhost object. run the application and resize the form.

I've googled around a bit looking for some type of solution. I keep coming across this post but it doesn't solve my problem.
