Thetype exposes the following members.
When another project calls IsSpecificDocumentViewOpen to request an item that your project has open, the environment will call Query Interface on your project for IVsHierarchy to obtain a pointer to your IVsSupportItemHandoff implementation. Your IVsSupportItemHandoff implementation should call TransferItem to transfer the item from your project to the project requesting the item.Notes to Implementers
Implement this interface to support transferring an item from your project to another project that wants to open the item. Implement this interface on your project object (IVsProject3) where you also implement IVsHierarchy.
