Failure has occurred loading type after CU2 for BizTalk 2013R2

Question

After installing CU2 in BizTalk 2013R2 we got the following error

Failure has occurred loading type

It looks like it is occurring in the map on the port

Answer 1

There is an explanation of the issue in this blog BizTalk 2013 R2 CU2 – Failure has occurred while loading a type where apparently they have introduced a new Use XSLT transform attribute in the map, grid properties under Standalone. Setting this attribute and redeploying fixes it, but that may be too much risk for a Production environment,

It has been raised with Microsoft, and hopefully will get released as a hot fix.

For now, if you can do without CU2 I would hold off on applying CU2 until it is fixed or the hotfix is available.

UPDATE: Microsoft released a new CU2-package with a hotfix for the problem. You can download it at https://support.microsoft.com/en-us/kb/3119352
