Cannot get WCF Data Services samples to run

Running Windows 7 Enterprise. VS2013 installed.

I am unable to run any WCF Data Services applications. (e.g. http://code.msdn.microsoft.com/WCF-Data-50-for-OData-v3-53074189)

I receive the following exception:

Configuration endpoint extension 'standardEndpoints/webHttpEndpoint' could not be found. Verify that this endpoint extension is properly registered in system.serviceModel/extensions/endpointExtensions and that it is spelled correctly.

I had a coworker try and they were able to run the sample immediately with no exception.

I feel like this means some sort of WCF component is missing, but Google is of no help on this one.

Can anyone help?

I figured it out.. the problem was that I was somehow missing the extension definition for webHttpEndPoint in my machine.config.

e.g.

  <system.serviceModel>
    <extensions>            
        <endpointExtensions>                
            <add name="webHttpEndpoint" type="System.ServiceModel.Configuration.WebHttpEndpointCollectionElement, System.ServiceModel.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />                
        </endpointExtensions> 
    </extensions>
  <system.serviceModel>

From MSDN - Deploying an Internet Information Services-Hosted WCF Service

Ensure That IIS, ASP.NET and WCF Are Correctly Installed and Registered

WCF, IIS, and ASP.NET must be installed for IIS-hosted WCF services to function correctly. The procedures for installing WCF (as part of the WinFX), ASP.NET and IIS vary depending on the operating system version being used. For more information about installing WCF and the WinFX, see Microsoft .NET Framework 4 Web Installer. Instructions for installing IIS can be found at Installing IIS.

The installation process for the WinFX automatically registers WCF with IIS if IIS is already present on the machine. If IIS is installed after the WinFX, an additional step is required to register WCF with IIS and ASP.NET. You can do this as follows, depending on your operating system:

• Windows XP SP2, Windows 7, and Windows Server 2003: Use the ServiceModel Registration Tool (ServiceModelReg.exe) tool to register WCF with IIS: To use this tool, type ServiceModelReg.exe /i /x in the Visual Studio command prompt. You can open this command prompt by clicking the start button, selecting All Programs, Microsoft Visual Studio 2012, Visual Studio Tools, and Visual Studio Command Prompt

• Windows Vista: Install the Windows Communication Foundation Activation Components subcomponent of the WinFX. To do this, in Control Panel, click Add or Remove Programs and then Add/Remove Windows Components. This activates the Windows Component Wizard.

• Windows 7:

Finally you must verify that ASP.NET is configured to use the .NET Framework version 4. You do this by running the ASPNET_Regiis tool with the –i option. For more information, see ASP.NET IIS Registration Tool

I've seen this issue before with configuring WCF services to run on newly stood up servers and dev/staging environments that I've stood up from scratch. The information on this link has assisted multiple times with this.
