Cumulative Update 7 for Microsoft BizTalk Server 2016

CU 7 for BizTalk Server 2016 has been released, and also Microsoft BizTalk Server 2016 Feature Update 3 with CU7

Important: Do not mix installing CU’s and Feature packs.

This CU contains

  • Four fixes/improvements for the SFTP adapter.
  • One fix for the IBM MQ.
  • One improvement for the the MQSeries adapters.
  • One fix for SAP (NCo) adapter.
  • One fix for the HL7 BizTalk Server Accelerators.
  • Five fixes around applying CU’s, Feature Packs and other setup and configuration changes (not counting the SFTP one which I’ve counted under adapters).
  • And a JSON FIX: JSON encoder unable to handle XML schema with the same name for record and one of its elements which is an issue that has caused grief for a few people.

Note: It has been reported on Twitter that “We have some issues with the new #biztalk CU7. The json encoder has started formatting boolean values as string values, like “true” instead of true.” and “As we wanted the FTP fixes in CU7 we installed it anyway and replaced the jsonextension dll with an older version.”

In that same thread “Little warning, rolling back CU7, does not rollback the jsonextension version.”

Also JSON encoder pipeline doesn’t create json array after installing CU7

Cumulative Update package 6 for BizTalk Server 2013 R2

CU 6 for BizTalk Server 2013 R2 is out, details are here.


There are 16 issues fixed in this CU.

There are 6 fixes to do with the SAP adapter to do with the NCo connection type.  So if you use that and are having issues you will probably want to release this to your test environments ASAP and re-test.

There are 2 fixes to do with File receive locations using alternate credentials.

2 fixes for the MIME/sMime pipeline component.

1 Fix each for the JSON decoder, MQ Series adapter, FTP adapter, message tracking and BizTalk DTA.

For some reason they have not yet updated the page Service Pack and cumulative update list for BizTalk Server to include this CU as yet.

BizTalk 2013 R2 known bugs, issues & quirks

Below a list of know bugs, issues, & other quirks* of BizTalk 2013 R2 (mainly CU3) and Visual Studio 2013 (update 4) , but I will update with fixes as the CUs come out or when I know about a new issue, so if you have another one I will add it (and link to it if you have a blog about it) if you let me know.  This in addition to the ones listed by Microsoft on Known Issues in Installation, Configuration, and Deployment

I’ve now posted the below article on a TechNet wiki

* My definitions for classifying these are
: Causes negative impact and no known work around or requires a lot of effort to work around.
Issue: Causes negative impact but has an easy or quick work around.
Missing: A feature that BizTalk doesn’t have that would make our life easier.
Quirk:  Something strange or unusual but does not cause a negative impact so far as known.

BizTalk JSON Decoder changing date-time timezone

While doing some work with JSON payloads being received in BizTalk we came across the interesting fact the the BizTalk JSON Decoder will in some situations change the time zone that the date-time was expressed in, even if we did not have a schema that specified these fields as being a date-time (either no schema or the field defined as a xsd:string)

BizTalk JSON Decoder – representation of XML attributes

I recently had to expose a web-service as a RESTful JSON one using BizTalk 2013 R2 using the WCF-WebHttp adapter and a JSON decoder in the pipeline.  There are plenty of blogs about how to that and it is fairly straight forward.  However I had a bit of difficulty when a decision was made to use an existing XML schema and to allow the JSON equivalent of that.  This XML schema made extensive use of Attributes.
