DeviceEx.FromPointer() throws an exception

[GoogleCodeExporter]

I am trying to wrap a DeviceEx object around an existing native IDirect3D9Ex 
object.
When I do this:
refSlimDXDevice9Ex = 
SlimDX::Direct3D9::DeviceEx::FromPointer((IntPtr)pNative->pD3DDevice);

I get the following exception from inside SlimDX:
A first chance exception of type 'System.InvalidCastException' occurred in 
SlimDX.dll

The regular Device.FromPointer() does work, but it does not give me any way to 
access the DeviceEx functionality (I cannot cast Device to DeviceEx, even 
though I created the Device from an IDirect3D9Ex object).

The same issue does not occur with Direct3DEx.FromPointer().
I do the same there:
refSlimDXDirect3D9Ex = 
SlimDX::Direct3D9::Direct3DEx::FromPointer((IntPtr)pNative->pD3D);

And that works without a problem.

I am using the SlimDX June 2010 SDK.

Looks like we don't overload for proper behavior here.
