Workflow service - bookmarks not resuming

Workflow service - bookmarks not resuming

pI have a very simple workflow service created using WF 4.5, that I'm
running from a console app in VS.NET 2012 (added a service reference). In
the WF service, I have a single ReceiveActivity that creates an instance
of the service and then immediately after invokes a NativeActivity which
uses a FileSystemWatcher/bookmarks to monitor a directory for incoming
files. Two issues arise:/p ol lipThe workflow goes idle and never gets
resumed when the file actually is dropped into the folder. The service
goes idle/shown as such in the persistence store, but is never
resumed./p/li lipThis is a whole separate issue, but what I ultimately
need to accomplish is to also institute a warning/error timeouts if the
file isn't there within a given timespan. Seems like creating a Pick
activity with three branches (two delays and the actual file monitor
activity) is the way to go; does this sound right?/p/li /ol pI'm not sure
how to get # 1 above working and/or there's a better approach. Any
thoughts/advice would be greatly appreciated - thanks in advance!/p
