Remover service reference to SlPortal and add service reference to MobilePortal and WcfPortal
de-reference SlPortal and reference MobilePortal
I suspect the following files aren't needed since they aren't referenced in csproj
WcfPortal.wsdl
WcfPortal.xsd
WcfPortal1.wsdl
WcfPortal1.xsd
WcfPortal2.xsd

WcfPortal2.wsdl is referenced in csproj file
