Well. Entity framwork is a repository which will load relations, typically when they're accessed. So if you don't access the related thing it won't get loaded.

But the easy way is to simply return a new type from your Linq. Of cause this can be a predefined transport object populated, or simply declared on the fly.

for instance

_dbContext.MyMainEntityTable.First(a => a.id = whatnot).select(s => new NotTheChildObject{ WantedValue = s.Value1, AnotherWantedValue = s.Value2 });

this will return a new class NotTheChildObject with two members: WantedValue, AnotherWantedValue
