First of all, I admit I am new in Windows Phone 8 application.So do not rate it as low. So please forgive me.
I have created WCF service, I am getting the results but when I run in windows phone, its returning error: "System.ServiceModel.CommunicationException", and I know why this is happening, it is occuring due to network problems.
My emulator is not getting netowrk from my system, I have Wifi network, and if there is no internet in my system, in case I have given static IP. That is the problem. How to solve this issue?
I had the same issue as well. However as someone else pointed out on the official forums it didn't work if you had a static IP for your PC set up in your router. Removing it and let the DHCP assign my PC an IP solved the issue for me.
