Namespace
HelixToolkit.SharpDX.Core
Assembly
HelixToolkit.SharpDX.dll

Limitation: Under switchable graphics card setup(Laptop with integrated graphics card and external graphics card), only monitor outputs using integrated graphics card is fully supported. Trying to clone monitor outputs by external graphics card, the clone window must reside in those monitors which is rendered by external graphics card, or error will be occurred.
