/ / I also want to know how to load DX under C #.
First to MS, download SDK: http://www.microsoft.com/downloads/details.aspx?familyid=fd044a42-9912-42a3-9a9e-d857199f888e&d857199f888E&DisplayLANG=EN
When installing, I will run after the installation of all installation options: /redist/directx9/dxsetup.exe / installManageddx
At this time, many DLLs will appear in C: /Windows/Microsoft.Net/Managed DirectX / V9.02.2904 or similar
When you add a reference, you can find a DLL in this.
