Can't add web service reference to mvc 4 project - asp.net

Question

I have created a web service in Visual Studio 2012 using the WCF service application template.
Everything works fine, but only if the host appliction is inside the same solution as you can see in this picture:
Bank project is the web service
BankHost project is Windows forms project
but when I am trying to get reference to the service from an ASP.NET MVC 4 project I am getting this error:
This is the web.config file of the web service project
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5"/>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
This is my web.config file of the MVC 4 project:

Answer 1

Check your .svc file - does it have the HostingFactory attribute?
Factory="WebApplication1.MyServiceHostFactory"
The name of the factory is Your service name + HostFactory and the whole path is the actual namespace, where your .svc file is located.
