A few days ago, I publish the first version of the community project BizTalk Pipeline Components Extensions Utility Pack for BizTalk Server 2016. Today I please to announce that a new pipeline component was added to this project: Multi-Part Message Attachments Zipper Pipeline Component.

This was an old component that I had published in the past for BizTalk Server 2006/2006 R2/2009 and 2010 that I now updated and improved to BizTalk Server 2016 with the help with my internal team at DevScope, in special, Pedro Almeida.

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 out-of-the-box pipeline capabilities.

BizTalk Pipeline Components Extensions Utility Pack: Multi-Part Message Attachments Zipper Pipeline Component

Multi-Part Message Attachments Zipper Pipeline Component

The BizTalk Multi-Part Message Attachments Zipper is a pipeline component for BizTalk Server which can be used in a send pipeline and is intended to replace all attachments of a multi-part message for its zipped equivalent.

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 include in a multi-part message that is not included in the message body (Message Body Part = False), compresses it and attaches the compressed attachment back to the message.
  • This component requires one configuration that is the FileExtension where you can specify if you want 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 “Pipeline Components“ folder that exists in 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 BizTalk Server Open Source Community repository on GitHub ( and everyone can contribute with new pipeline components that can extend or improve the 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.
