As a quick reminder, for BizTalk Developer Tools please also update/install version 184.108.40.206 of the BizTalk Server Visual Studio extension in addition to installing the CU package. The extension can be installed from https://marketplace.visualstudio.com/items?itemName=ms-biztalk.BizTalk or from within Visual Studio – Manage Extensions. Please note that we have not updated the extension since CU1 so you can skip this step if you have already installed it previously.”
