This is an amazing tool to have, one of my resources deleted a BizTalk Map, in came the dissasembler for Reflector and the XSLT was generated from the DLL, ufff… It did save us a lot of time(About to be deployed to PRD).
The disassembler can generate schemas, xslt, orchestartions, pipelines etc…
its a must have for every BizTalk Devloper out there.
