Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata?

I'm going to say it's because you don't have an address for your endpoint in the web.config.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
