How to deploy / access SharePoint lists with an AppModel app?

Question

I have an AppModel app (Provider hosted, on-premise) and I am trying to add a SharePoint list to deploy with it.

However, the list just seems to be silently ignored - when I deploy and run the app in visual studio, and query the lists with the following C# code, my "FavoriteFoods" list is missing (but other lists are displayed)

Uri hostWeb = new Uri(_httpContext.Request.QueryString["SPHostUrl"]);

using (var clientContext = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostWeb, _httpContext.Request.LogonUserIdentity))
{
    var web = clientContext.Web;

    clientContext.Load(web, w => w.Lists);
    clientContext.ExecuteQuery();

    return web.Lists.ToList().Select(x => x.Title).ToList();
}

Edits

• oddly enough, I am able to add the list programmatically, e.g. with clientContext.Web.Lists.Add(new ListCreationInformation() { Title = "Blah" });.
• The deployment location for the Elements.xml files is specified as
  • {SharePointRoot}\Template\Features\{FeatureName}\FavoriteFoodsInstance\
  • {SharePointRoot}\Template\Features\{FeatureName}\FavoriteFoods\

How can I get the list to deploy and be accessible within the AppModel project?

Other Information:

My most deeply nested Elements.xml file:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <ListInstance Title="FavoriteFoods" OnQuickLaunch="TRUE" TemplateType="10000" Url="Lists/FavoriteFoods" Description="My List Instance"></ListInstance>
</Elements>

The other Elements.xml file:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<!-- Do not change the value of the Name attribute below. If it does not match the folder name of the List project item, an error will occur when the project is run. -->
<ListTemplate
    Name="FavoriteFoods"
    Type="10000"
    BaseType="0"
    OnQuickLaunch="TRUE"
    SecurityBits="11"
    Sequence="410"
    DisplayName="FavoriteFoods"
    Description="My List Definition"
    Image="/_layouts/15/images/itgen.png"/>

The AppManifest.xml permissions requests:

<AppPermissionRequests>
   <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web" Right="FullControl" />
</AppPermissionRequests>

Answer 1

Any list you deploy as part of you App will be added to the AppWeb (yes such a web is created when you add SharePoint items to your App, even though the App is Provider hosted) not to the HostWeb

Answer 2

You'll find details on how to create a cloud-hosted app (provider-hosted or autohosted) that includes a custom SharePoint list and content type there :

http://msdn.microsoft.com/en-us/library/fp179936.aspx

It is using two apps with cross-domains javascript or OAuth & REST OData webservices to communicate between them. As you'll see, it is using the SPAppWebUrl instead of SPHostUrl because the lists are in the App Web created for the app.

This is thus possible but sometimes it is easier to create your list programmatically if it doesn't exists, thus allowing you to have the list in the main sharepoint site instead of in an app web.
