A few days ago, I published the first version of the community project BizTalk Pipeline Components Extensions Utility Pack for BizTalk Server 2016. Today, I am pleased to announce that a new pipeline component was added to this project: the Multi-Part Message Attachments Zipper Pipeline Component.
This was an old component that I had previously published for BizTalk Server 2006/2006 R2/2009 and 2010, and I have now updated and improved it to BizTalk Server 2016, with help from my internal team at DevScope, in particular, Pedro Almeida.
📝 One-Minute Brief
An introduction to the Multi‑Part Message Attachments Zipper pipeline component, which compresses all non‑body parts of a BizTalk multi‑part message into a single zipped attachment using a custom send‑pipeline component.
What is BizTalk Pipeline Components Extensions Utility Pack?
BizTalk Pipeline Components Extensions Utility Pack is a set of custom pipeline components (libraries) with several custom pipeline components that can be used in received and sent pipelines, which will provide an extension of BizTalk’s out-of-the-box pipeline capabilities.

Multi-Part Message Attachments Zipper Pipeline Component
The BizTalk Multi-Part Message Attachments Zipper is a pipeline component for BizTalk Server that can be used in a send pipeline and is intended to replace all attachments of a multi-part message with their zipped equivalents.
The capabilities are similar to those available in compression software such as WinZip or 7-Zip:
- Attachments Compression – Extracts, in a send pipeline, all message parts of a multi-part message that are not included in the message body (Message Body Part = False), compresses them, and attaches the compressed attachment back to the message.
- This component requires one configuration: FileExtension, which you can use to specify, for example, a .zip or .gz file.
No compression/decompression software needs to be installed in the BizTalk Server machines.
To use this pipeline component in your projects, you just copy the PipelineComponentMultipartMsgZipAttach.dll file into the Pipeline Components folder that exists in the BizTalk Server Installation directory: ..\Program Files (x86)\Microsoft BizTalk Server <version>\Pipeline Components on every server.
You do not need to add a custom pipeline component to be used by the BizTalk Runtime to the Global Assembly Cache (GAC).
The project is available on the BizTalk Server Open Source Community repository on GitHub (https://github.com/BizTalkCommunity), and everyone can contribute new pipeline components to extend or improve existing BizTalk Server capabilities.
At the moment, it is only available for BizTalk Server 2016, but it will soon be compiled and available for previous versions of the product.
