how to add a WPF dialog to a Winforms project

I am using Visual Studio 2008 targeting .net 3.5 framework. I need to add a WPF dialog to a Winforms project. I was thinking that by adding reference to PresentationCore, PresentationFramework and Wi开发者_StackOverflow中文版ndowsBase.dll and copying a WPF dialog from a test WPF project to the WinForms project in question should do the trick, but after that when I try to open in designer a WinForms dialog studio just crashes and closes. So basically the question is how to add a WPF dialog to a WinForms project? Thanks

Create the dialog as a WPF UserControl Library. Add it to the Windows Form application by using Project->Add Existing Item. Add an ElementHost component to the Windows Forms form. Set the HostedContent of the ElementHost to the WPF User Control.
