How to use custom pipeline dlls in Biztalk Projects so that they appear in the send/receive pipeline configuration after deployment?

Question

I have a existing Biztalk application that uses custom pipelines for receiving excel files. I have the dll of that custom pipeline. Now i created another BT application that needs to use that same custom pipeline. But after i deploy the application in
Biztalk, i can't see the  pipeline available in Receive pipeline configuration combo box during configuration. I have referenced the custom pipeline dll in my project before deploying, but that doesn't help. I also copied the dll in the C:\Program Files
(x86)\Microsoft BizTalk Server 2010\Pipeline Components folder and C:\Program Files (x86)\Microsoft BizTalk Server 2010 folder, but that doesn't make the pipelines appear during configuration too.
Can anyone give any idea on how can i use these custom pipeline dlls in project so that they appear in configuration after deployment?

Answer 1

If you plan on using the deployed pipeline across multiple applications in BizTalk, the BizTalk Application (using the BizTalk Server Administration Console) should have the other application [where the pipeline is deployed] as reference.
For e.g.: Custom Pipeline (myCustomPipeline) part of a BizTalk Project (dll - myCustomProject.dll) deployed under Application [Some Application] also to be used in another BizTalk Application [Some Other Applicaiton] then using BizTalk Server Administartor
right click the "Some Other Application" and select "Properties"
on the "Properties" page, left hand side, select "References"
on the right-hand side, use "Add" to add the "Some Project" as a reference.
Doing so will ensure that ALL resources (maps, schemas, orchestrations, send ports, receive locations, rules, etc.) deployed for "Some Application" are available/referensible in "Some Other Application".
