Hi,

I have an application that populates a couple of generic dictionaries (via calls to a web service) when it starts up.
This works fine when there is only one instance of the application running.
I run into problems as soon as there are more than one instances running at the same time.
The second and subsequent instances always timeout while populating those dictionaries.
So I'm thinking about trying to have the first instance populate the dictionaries and provide some method for any subsequent instances to search and add items to them.
As far as I can tell WCF will cater for this type of scenario, but I would like to get some confirmation/denial from people who know more about WCF than I do (I have never used it).

The general run of things would be:

1. 1st instance is started and it immediately starts filling the dictionaries
2. 2nd, 3rd, 4th instances are started, they will read from and add items to the dictionaries
3. The dictionaries need to be available for as long as any instances of the application are running

Is this possible using WCF? Any suggestions on how I might go about this? I'm not looking for code (not yet anyway, I'm sure I'll have problems along the way), more like a general overview on how to proceed.

Thanks,

David
