Nhibernate projection with child collection NHibernate QueryOver projections - projecting collections to DTO NHibernate Projections - how to project collections So I was wondering what would be a good work around to project a child collection to my DTO.

I have two classes : public class Parent { public int Id { get; set; } public string Name { get; set; } public ICollection<Child> Childrens { get; set; } } public class Child { public int Id { get; set; } public string Name { get; set; } } Now through Nhibernate QueryOver I want to get list of all Parent with no of Count of children in single query. Expected output is ?: ParentId Name ChildrenCount 1 ABC 10 2 CDE 5 can anyone help me .
