BizTalk supported Microsoft .Net Frameworks & August 2019 Windows Updates

The August 2019 Windows Updates includes .Net 4.8, however most BizTalk versions only support specific version of .Net, and installing a unsupported version of .Net has caused issues in the past. So if you are patching BizTalk servers, make sure to block installing any unsupported .Net Version.

Important: If the wrong version of .Net get’s installed and it breaks BizTalk, make sure you back up the machine.config files (32 and 64 bit) BEFORE you uninstall the incorrect .NET version and re-install the correct version as you will need to re-add those settings.
