Hi,

I have to create several services that have to use some sort of registry, to store and get data from. Also, services should have to communicate with each other, in order to exchange data, using the previously mentioned registry.
Each service should be able to connect to the registry in order to get data.

I've created the individual WCF services, but how to create the registry ? Should the registry also be a wcf service?

Thanks, but here's my problem. I'm new to WCF and I have to implement communication between applications. For instance application 1 sends an encrypt message to application 2 and application2 send an encrypt message to application 1. How to implement this?

Should i develop 2 seperate wcf services and 2 separate clients that use these services, and if so, how to connect these two services?
