Hi, I'm trying to write a simple IM which will be based on WCF. For NAT traversing I use STUN method to get public addresses of peers. That implies the use of UDP transmission, but it is not implemented in WCF. I found the UDP Transport Sample and I managed to set up the service, but i have problems to configure the client. Client receives the address of service and has to configure the connection from the code, without use of App.config file. I'll be thankful for any help
