I suggest you look at the new static analysis features/attributes in C# 8: [^] Quote: AllowNull: A non-nullable input argument may be null. DisallowNull: A nullable input argument should never be null. MaybeNull: A non-nullable return value may be null. NotNull: A nullable return value will never be null. MaybeNullWhen: A non-nullable input argument may be null when the method returns the specified bool value. NotNullWhen: A nullable input argument will not be null when the method returns the specified bool value. NotNullIfNotNull: A return value isn't null if the argument for the specified parameter isn't null. DoesNotReturn: A method never returns. In other words, it always throws an exception. DoesNotReturnIf: This method never returns if the associated bool parameter has the specified value. I recommend Jonathan Allen's coverage of these features on InfoQ: >[^] «One day it will have to be officially admitted that what we have christened reality is an even greater illusion than the world of dreams.» Salvador Dali

Guilty as charged. Local EMS classes have this on there forms for initial medical assesments... I think most of us would understand this SAMPLE = { Symptoms: Allergies: Medication: PertinentHistory: LastMeal: Events: } Same thing for vital signs. And the ER directors are on board.

Not sure about that, never had to change CSS dynamically like that. I could imagine you'd either send the file green-theme.css or blue-theme.css, but not switch it with AJAX or even WebSockets. By the way, when you use a preprocessor like LESS, SASS, or SCSS you can use a variable. // green-theme.scss $primary-color: green; // blue-theme.scss $primary-color: blue; // theme.scss .node { background-color: $primary-color; } Now you only have to switch or overwrite some variables instead of writing your complete theme twice :D See also my reply to Marc Clifton below.

Why did they shift the single step in VS from F5 to F11? Is that some plot by left handers?
