Solution & Explanation
The reason that all the customer’s workflows had stopped working is that this issue affects any web application that relies on the newly-required .NET types. The fix is to add the newly required types to each web application’s configuration file. This is most easily accomplished via the PowerShell script provided by Microsoft in the support article mentioned above.
In addition, if your organization is running workflows on the central admin web application, then its configuration file must be updated manually. The PowerShell script does not update the central admin web application.
Updates – especially
security updates – are extremely important to the health and well-being of any SharePoint farm. In general, the best practice is to first apply updates in a testing environment in order to ensure that no existing functionality is affected. Accidents do happen, however – and that’s where SharePoint support specialists such as Total Solutions can help.
