Are there any code coverage tools for manual testing? For example, if I write 30 new lines of code, compile, then run, is there any way to quickly verify that all 30 lines were run? Also, later, after I've checked the code into an official build, is there any way that I can verify that the test department hit on all 30 lines of code ...
What is the preferred way to store user-level information for .NET application. I could have used registry or config files - but some users don't have enough permissions to save/load from these.

It seems to me that it'd be useful to be able to tell at a glance that a class is abstract and not meant to be directly instantiated just like it's useful to be able to easily identify an interface. My question is, why didn't "AFourLeggedAnimal : IAnimal" catch on? Is it simply because of the possible confusion (which I just noticed wh...

On a previous project I used single root inheritance for my MVC viewModel. Everything worked and was effective at giving data to the Site master, but was a bit of a pain in the controller actions. To properly construct the root view data each time, we had to override (using method hiding) Controller.View(). I'm tempted to try attribut...
