We're migrating few of the files from older frame work to VS2103 FW-4.5.1. On migrating one of the Solution files there is a reference to Interop.VIBBTSCompLib.dll, but I'm unable to find such a dll or any other higher level DLL. Also on little more search seems like this is related to BizTalk Server, but I'm unable to find any of the references in Visual studio 2013,
The definitions and functions using this reference are "BTSComp", "BTSCompClass()" and "ProcessMessage(XMLText)".
