WPF WindowsFormsHost VS2008 Toolbox has grayed out all the Windows Forms controls

I'm trying to use WindowsFormsHost in a WPF app so I can use some Windows Forms components.

<Grid>
    <WindowsFormsHost>

    </WindowsFormsHost>
</Grid>

This all works ok with no errors, but when I go to drag a Windows Forms component from the toolbox in VS2008, they're all grayed out. In a way this makes sense as only the WPF components are available. But how do you drop a Windows Forms component onto a WindowsFormsHost if they're all grayed out and unavailable?

From stackoverflow

• I don't think WPF designer supports Windows Forms components. You need to specify these in the XAML or in code. A simple example of how to add a WinForms button into a WPF application. Note that the button isn't visible on the design surface.

  <Window x:Class="DataTemplateBind.Window1"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:forms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
      Title="Window1" Height="300" Width="300">
  
      <WindowsFormsHost Height="200" Name="windowsFormsHost1" Width="258" >
          <forms:Button Text="Waaa :("></forms:Button>
      </WindowsFormsHost>
  </Window>
  

  Note the added xmlns:forms namespace which isn't there by default.

  Mitch : Thanks Mikko, that did it. I was at the end of a long day and the frustration was setting in!
