    <p>I have created a Generic repository with some methods on top of EF Codefirst, which works great. The Get method looks like this (this has include for one level)</p> <pre><code>public virtual IEnumerable&lt;T&gt; Get( Expression&lt;Func&lt;T, bool&gt;&gt; filter = null, Func&lt;IQueryable&lt;T&gt;, IOrderedQueryable&lt;T&gt;&gt; orderBy = null, string includeProperties = "") { IQueryable&lt;T&gt; query = _dDbSet; if (filter != null) query = query.Where(filter); query = includeProperties.Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries).Aggregate(query, (current, includeProperty) =&gt; current.Include(includeProperty)); return orderBy != null ? orderBy(query).ToList() : query.ToList(); } </code></pre> <p>But I stumble on a problem when I need the generic repository to return a 'deeper' include</p> <p>An example: A Hotel object have a relation to a list of rooms and each room have a relation to person.</p> <p>I want my method to return a Hotel object with a list of rooms with the person of those rooms related.</p> <p>How can I solve this by using a GenericRepository?</p> <p>I do not want to use the solution:</p> <pre><code> var hotel = _hotelRepository.Context.Hotels.Where(p =&gt; p.HotelId == HotelId).Include(p =&gt; p.RoomList.Select(b =&gt; b.Person)).First(); </code></pre> <p>in my bussinesclass because I want to seperate out the data access to the genericRepository and be able to Mock out the method in my test project.</p> <p>Is there a good solution for this, or do I have to use the context with a Select as mentioned above?</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
