/// To share a resource between two Direct3D 10 devices the resource must have been created with the <see cref="SharpDX.Direct3D11.ResourceOptionFlags.Shared"/> flag, if it was created using the ID3D10Device interface. If it was created using the IDXGIDevice interface, then the resource is always shared. The REFIID, or GUID, of the interface to the resource can be obtained by using the __uuidof() macro. For example, __uuidof(ID3D10Buffer) will get the GUID of the interface to a buffer resource. When sharing a resource between two Direct3D 10 devices the unique handle of the resource can be obtained by querying the resource for the <see cref="SharpDX.DXGI.Resource"/> interface and then calling {{GetSharedHandle}}.
