DXDeviceIsDebugDevice Property

Gets a boolean that specifies if the created Device was created with Debug layer. Note that this property can be false even when the CreateDebugDirectXDevice is true. This indicates that the debug device cannot be created. This can be cased because debug layer is disabled in "DirectX Control panel" or the Debug layer is not installer on the system (it is usually installed with Visual Studio or with Windows SDK).

public bool IsDebugDevice { get; }
