Simple WCF Service for my Windows Phone ToDO App (it si a learning project). Service is prepare for IIS hosting. I had some problems with self hosting then i choose for IIS hosting. Service use TransportWithMessageCredential secutity mode. For that you need sll certificate. I use self sign certificate. Common name of certicicate must be server name. Then you transfer via (Dropbox.. ) your certificate to your Windows Phone emulator.
I will describe more in future.....
