15. .NET 과 DirectX 9 Managed Programming What is Managed DirectX? What is Managed DirectX? Managed DirectX Namespace Managed DirectX Namespace

16. What is Managed DirectX? A thin wrapping of DirectX to provide support to CLS Compliant Languages (i.e. C#) A thin wrapping of DirectX to provide support to CLS Compliant Languages (i.e. C#) Eliminates using COM interop or the DXVB library Eliminates using COM interop or the DXVB library  Removes performance cost of COM interop  Using the DXVB library was unsupported

17. What is Managed DirectX? Features supported in Managed DirectX Features supported in Managed DirectX  Graphics  Feature parity with Direct3D, D3DX  DirectDraw ® (DirectX 7 level interfaces)  Audio  Feature parity with DirectSound ®  Input  Feature parity with DirectInput ®  Networking  Feature parity with DirectPlay ®  Video  Simple audio/video playback functionality  Diagnostics  Easily access data provided by DxDiag
