Hi Jeff,

From your description, you have multiple windows form applications deployed
on multiple machines in a local intranet environment and will need to
synchronize some certain status data at runtime, correct?

As for the shared and hierarchical data, are they freqently changed(by all
those client winform programs or may receive updated data from a central
backend data store)?

If the data is frequentely changed and will need to be sychronized among
all those clients whenever any client node update it, I think you may
consider the following approach:

** for the shared data objects which have complex hierarchy, you can use
.net custom class (mark as serializable ) to represent them and binary
serialize them when need to transfer between multiple client nodes over
network.

** Use raw socket interface to transfer the data between the center data
center and all those client nodes. Thus, the data center can work like a
UDP server which can receive update request from all client nodes and
whenever one node update the shared data, center can use UDP "broadcast" to
send notification to all other client nodes.

Using socket here is for performance consideration. Of course, other
districuted service like remoting or WCF can also do the same job, but may
involve some additional overhead.

Sincerely,

Steven Cheng
