The mobile service project has a similar structure to our MVC projects and more so the Web API project because it's built on the same technology. We have an App_Start folder with a WebApiConfig class, which takes care of initializing and configuring the application, and a Controllers folder with a TodoItemController sample class, which is a special type of API controller that is strongly bound to the EntityData type models, which have a number of default fields enforced by the ITableData interface:

public interface ITableData
{
    [JsonProperty(PropertyName = "__createdAt")]
    DateTimeOffset? CreatedAt { get; set; }
    [JsonProperty(PropertyName = "__deleted")]
    bool Deleted { get; set; }
    string Id { get; set; }
    [JsonProperty(PropertyName = "__updatedAt")]
    DateTimeOffset? UpdatedAt { get; set; }
    [JsonProperty(PropertyName = "__version")]
    [SuppressMessage("Microsoft.Performance", 
    byte[] Version { get; set; }
}
