“You are making my point!”

I needed to do some custom pipeline work using CForwardOnlyEventingReadStream class. And I spent nearly 10 minutes searching for Microsoft.BizTalk.Streaming.dll. It is frustrating to see it seems changing location in GAC in every release. Why could we just put in the BizTalk installation directory as all the other DLLs are?

Anyways, here it is: “C:\ Windows\ assembly\ GAC_MSIL\ Microsoft.BizTalk.Streaming\ 3.0.1.0__31bf3856ad364e35″. Note that the only way to reference it is to fish it out of GAC using elevated command line as shown below.

BTW, if you are curious why I need this DLL, or if you haven’t used/heard of this DLL before, you need to do some digging. This is the single most important DLL when programing BizTalk pipeline components. See Optimizing Pipeline Performance.

Happy streaming in BizTalk Pipeline!
