Question

I have a query below that works but was wondering if there is a cleaner way to implement it.

var query = Context.Alerts
                .Where(a => a.AlertsDismisseds.Where(d => d.AlertID == a.AlertID)
                .Count() == 0)
                .Select(a => a);

I am looking to select all the Alerts from a table if there are not in the AlertsDismisseds table.

Thanks in advance.

var query = Context.Alerts
                .Where(a => !Context.AlertsDismissed.Any(d => d.AlertID == a.AlertID))
