Direct3D11.Device.GetSupportedFeatureLevel() throws exception

[GoogleCodeExporter]

When calling Device.GetSupportedFeatureLevel() in Direct3D 11, I get a
crash with the following exception details:

Message: E_INVALIDARG: An invalid parameter was passed to the returning
function (-2147024809)

Stack Trace:
   at SlimDX.Result.Throw[T](Object dataKey, Object dataValue)
   at SlimDX.Result.Record[T](Int32 hr, Boolean failed, Object dataKey,
Object dataValue)
   at SlimDX.Result.Record[T](Int32 hr, Object dataKey, Object dataValue)
   at SlimDX.Direct3D11.Device.GetSupportedFeatureLevel()
   at DX11Fun.Form1.Form1_Load(Object sender, EventArgs e) in
C:\Users\Matt\core\DX11Fun\DX11Fun\Form1.cs:line 39

I am calling the function like so:
FeatureLevel f = Device.GetSupportedFeatureLevel ();

System configuration:
Windows 7 Professional x64
Visual Studio 2010
.NET 4.0 (with the 2.0 runtime exception added in App.config so SlimDX can
load)

Intel Core 2 Quad Q9550 (no OC'ing)
8GB RAM
GeForce GTX 260 216 Core

Are you using the latest version from SVN?

Nope, with the latest SVN this works. Got the latest SVN and compiled it with 
VS2010 and this call works now.
