InstancedMeshGeometry3DNodeGetInstanceBuffer Method

public Buffer GetInstanceBuffer()

Return Value

GetInstanceBuffer returns a SharpDX.Direct3D11.Buffer that is used by this InstancedMeshGeometry3DNode.

If the instanceBuffer was created by this InstancedMeshGeometry3DNode, then it will be also disposed by this InstancedMeshGeometry3DNode - you must not dispose it because after that it will not be usable any more. The reason for this is that SharpDX does not support reference counting and so when a Dispose method is called, the object cannot be used any more (regardless of the references count number of the COM object). This is also a standard .Net practice - not to use Disposed objects any more.
