This is my webconfig code for the server:

  </system.webServer>

</configuration>

And this the web.config for the client

Answer 1

The below section of your servers web.config

  <services>
      <service name="Service1.svc.cs"  >
        <endpoint address="" binding="basicHttpBinding"
                  bindingConfiguration="Service1"
                  contract="IService1" >
        </endpoint>
      </service>
    </services>

has some values for attributes that are wrong. The value for the name attribute of service element needs to be namespace.Service1 and similarly the contract attribute value of endpoint element needs to be namespace.IService1 as shown below:

  <services>
      <service name="<namespace>.Service1"  >
        <endpoint address="" binding="basicHttpBinding"
                  bindingConfiguration="Service1"
                  contract="<namespace>.IService1" >
        </endpoint>
      </service>
    </services>

Just replace with the namespace of Service1 class. And that should work
