These assemblies are in the SDK\Bin folder, along with the corresponding Visual Studio IntelliSense XML files. More information: Assemblies included in the Microsoft Dynamics CRM SDK 2013

You may have a development scenario where you want to include the service reference in your project rather than using the assemblies. To find the correct service references for your organization, see Download the endpoints using the Microsoft Dynamics CRM 2013 Developer resources page.
