I have a very simple workflow in Visual Studio 2015 Update 3 consisting of a single WriteLine activity:
This console utility, Microsoft.Workflow.TestServiceHost.exe found in C:\Program Files (x86)\Workflow Manager Tools\1.0, attaches to the registered Workflow Manager instance and listens for messages written using the WriteLine activity
The workflow is deployed to an on-prem SharePoint Server 2013 Enterprise with Workflow Manager 1.0 Cumulative Update 3. Everything, SharePoint, Workflow Manager and Visual Studio, is installed on the same machine running Windows Server 2012 R2.
No matter what I do the TestServiceHost console does not show any of the messages from WriteLine activity. I can hit breakpoints inside the workflow, though, if I attach to the Microsoft.Workflow.ServiceHost.exe process.
Has anyone managed to make TestServiceHost working?
