When doing the Use Case for "Filling the Quiz", how should I signal there is a time limit and that after that the Use Case is finished?

I am a bit confused about where to describe the algorithm I might use in some part of an application. Let's say I want to create a Use Case that describes how the User inputs a set of values and my application returns the average of those values (of course this is a dead-easy case, but its easier to explain it this way). 1. The User t...

Before C# 4.0 came out, I was quite excited about covariance and contravariance. It pandered to my fondness for theoretical correctness! However, now that it’s out, and I’m back to writing normal, everyday, boring code, I’m starting to wonder: did I ever use it yet? And I notice that I haven’t used it consciously. None of the interfaces...
First off, apologies if this question has been asked before but I couldn't find anything that answers this directly. Here's my problem. I've inherited a product which has been designed to be so flexible that populating pretty much every combobox and textblock on the (silverlight) form requires a service request. Some of the screens ta...
