Application manifest defines the list of services and the parameters required to deploy these services. Following is an example:

<?xml version="1.0" encoding="utf-8"?> 
<ApplicationManifest xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ApplicationTypeName="NodeAppType" ApplicationTypeVersion="1.0" xmlns="http://schemas.microsoft.com/2011/01/fabric"> 
   <ServiceManifestImport> 
      <ServiceManifestRef ServiceManifestName="NodeApp" ServiceManifestVersion="1.0.0.0" /> 
   </ServiceManifestImport> 
</ApplicationManifest> 

The ServiceManifestImport element specifies the services that are included in the app.
