IIS 8 on WS2012 shows .svc as content - wcf

Question

I have a C# WCF web service that I setup on WS2008R2 and it works fine. I go into IIS and right-click JobService.svc, it opens up a browser and puts in a URL:
http://1.2.3.4/WebServices_DEV/JobService.svc
and the service shows. Absolutely fantastic!
However, I have a WS2012 server and I try to do the same.
If I open up IIS and right click on JobService.svc, it opens a browser and puts in the URL correctly.
However, it shows:
<%# ServiceHost Language="C#" Debug="true" Service="WebService.JobService" CodeBehind="JobService.svc.cs" %>
Now my web.config shows like this:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<security>
<requestFiltering>
<requestLimits>
<headerLimits>
<add header="Content-type" sizeLimit="100000" />
</headerLimits>
</requestLimits>
</requestFiltering>
</security>
<directoryBrowse enabled="true" />
</system.webServer>
<system.diagnostics>
<sources>
<source name="System.ServiceModel" switchValue="Information" propagateActivity="true">
<listeners>
<add name="ServiceModelTraceListener" type="System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" initializeData="wcf-traces.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>
</configuration>
I don't know whether it's that I am relying on not specifying end points or bindings so I add them in:
<standardEndpoints>
<webHttpEndpoint>
<standardEndpoint name="JobService" />
</webHttpEndpoint>
</standardEndpoints>
<bindings>
<basicHttpBinding>
<binding name="JobService" />
</basicHttpBinding>
</bindings>
But it has no effect.
What I am I doing wrong please.
Thanks.

It seems that IIS is missing handler mappings or Http Activation for WCF Services is disabled. Here is instruction how to fix it: IIS 8 missing handlers

Maybe this is a solution
First make sure you install the necessary feature about wcf in the windows feature.
You can check all about IIS, and all about .Net Framework 3.5, 4.5
and maybe tou should add the MIME type:
mimeMap fileExtension=".svc" mimeType="application/octet-stream"
add Service.svc to your default document
and run the site, I Success run the service.svc
