Support shadow navigation properties such that views over the navigations can function even when a CLR type doesn't have an actual navigation property. This would enable unidirectional many-to-many relationships like this:

class Post
{
  public int Id { get; set; }
  public ICollection<Tag> Tags { get; set; }
}

class Tag
{
  public int Id { get; set; }
}

builder.Entity<Post>()
  .HasMany(p => p.Tags)
  .WithMany();

Original issue:

Are there any plans to support this?

table.Include(t => EF.Property<Entity>(t, "Property"))
