Open close ServiceHost multiple times

Question

I am trying to figure out how to open and close a ServiceHost object multiple times in a self-hosted WCF app:

what I did: 1. create ServiceHost object

1. call Open()
2. call Closed() so far so good.
3. call Open() again, exception: Cannot access a disposed object, which is because CommunicationObject is disposed , makes perfect sense.

How can I open the ServiceHost again in this case without recreating that object again (rather, I'd recreate CommunicationObject if it is possible).

Thanks in advance.

Answer 1

ServiceHost inherits from CommunicationObject. ServiceHost is the CommunicationObject throwing the exception. Once a CommunicationObject is Closed it cannot be reopened. You'll have to create a new ServiceHost.

The CommunicationState state machine:

Every object starts in the Created state and proceeds in a one-way progression through the Opening, Opened, Closing, and Closed states.
