Using PredicateBuilder in Projections with child collections

Question

Hello !
I'm using PredicateBuilder ( From LinqKit).
This is my code :
Dim mylist as IQueryable(of MyObj1)
Dim pred1 = PredicateBuilder.True(Of Myobj1)()
Dim pred2 = PredicateBuilder.True(Of ch1)()
Dim pred3 = PredicateBuilder.True(Of ch2)()
pred1=pred1.And(Function(t) t.id=5)
pred2=pred2.And(Function(t1) t1.vl1>=7)
pred3=pred3.And(Function(t2) t2.quantity<=4)
mylist = (From t In context.Myobj1s.Where(pred1)Select New With { _
.Parent = t, _
.child1 = t.ch1s.AsQueryable.Where(pred2), _
.child2 = t.ch2s.Asqueryable.Where(pred3) _
}).ToList
But I'm getting this error :
The LINQ expression node type 'Invoke' is not supported in LINQ to Entities.
I try also to use AsExpandable  , but the problem is not resolved.
What can I do ?
Thank you !

Hello,
For issues regarding LinqKit, I suggest that you could contact the author of this tool
