let's say i want to check amount as coalesce then use nullable as mention in below code sample
context.order.where(w => w.status == "paid").sum(s => (nullable<int>) s.amount ?? 0)
score:4
have a look at null-coalescing operator
e.g.
string text1 = null;
string result = text1 == null ? "default" : text1 ;
you can do
string result = text1 ?? "default";
