I have a query like the one below where I want to be specific about which columns I want to get without projecting to a new type.
dbcontext.
SomeEntity
.Include(_ => _.ChildEntityA)
.ThenInclude(_ => _.SubChildEntityA)
.Include(_ => _.ChildEntityB)
.ThenInclude(_ => _.SubChildEntityB)
.ThenInclude(_ => _.SubSubChildEntityB)
.Include(_ => _.ChildEntityC)
.Include(_ => _.ChildEntityD)
.FirstOrDefault(_ => _.Id == 123)
I am fine projecting when doing small requests but when it gets complex then it becomes heavy to create whole chain of objects via new when there may be only one or two sub entities that you want to filter out which columns you want.
