Entity Framework - Include Multiple Levels of Properties

If I understand you correctly you are asking about including nested properties. If so :

.Include(x => x.ApplicationsWithOverrideGroup.NestedProp)

or

.Include("ApplicationsWithOverrideGroup.NestedProp")  

or

.Include($"{nameof(ApplicationsWithOverrideGroup)}.{nameof(NestedProp)}")  

EF Core: Using "ThenInclude" to load mutiple levels: For example:

var blogs = context.Blogs
    .Include(blog => blog.Posts)
        .ThenInclude(post => post.Author)
        .ThenInclude(author => author.Photo)
    .ToList();

For EF 6

using System.Data.Entity;

query.Include(x => x.Collection.Select(y => y.Property))

Make sure to add using System.Data.Entity; to get the version of Include that takes in a lambda.

For EF Core

Use the new method ThenInclude

using Microsoft.EntityFrameworkCore;

query.Include(x => x.Collection)
     .ThenInclude(x => x.Property);
