Include filter child collection [duplicate]

Answer 1

You can achieve this in EF Core itself:

var item = 
ctx.Order.Include("Inner")
         .Select(x => x.Inner
                .Where(innerItem => innerItem.IsDeleted))
         .FirstOrDefault();

Or,

var item = 
    ctx.Order.Include(o=> o.Inner
                     .Where(x => x.IsDeleted));
