Hello,
I do not know if this is the right forum, but I am looking for help with SharpDX 2.6. I have very simple
algorithm to create and draw a triangle. unfortunately, I see nothing.
Can anyone help ?

Of course several DLL need to be added
Microsoft.DirectX.dll
Microsoft.DirectX.Direct3D.dll
Microsoft.DirectX.Direct3DX.dll
Microsoft.DirectX.DirectDraw.dll
from Win XP, so called managed DirectX
