I'm trying to compile the "enumerating display adapters" sample which is in (SDK root)\Samples\Managed\Common\dxmutenum.cs. I've created a new project in VS .NET, added all the DirectX references but when I try to compile it I get three errors. They are... The type or namespace name 'IDeviceCreation' could not be found (are you missing a using directive or an assembly reference?) I get the above twice and... The type or namespace name 'DeviceSettings' could not be found (are you missing a using directive or an assembly reference?) I'm sure I'm missing something but I can't figure out what it is. Any ideas? Darrell
