RE: VB vs C# is there a auto documenting feature in C#

Excuse me, short-circuit is to confusing? I don't think so. If a person is a
programmer then they should be able to follow a language syntax. Just
because some of them can't, doesn't mean that it should not be included.
Thats like saying I shouldn't have an engine in my car since I don't
understand what all the little wires are for. 
 
Conditionals should never have side effects. Unless you really like
debugging and testing nightmares. Any decent optimizer can take an
assignment statement and a following if statement and make just as efficient
as a conditional with side effects. The difference is testability and
reliability. 
 
VB.net does have short circuit capabilities. I think the AndAlso and OrElse
are easier to read. Also, I the evaluation is from the left to the right, 
so it reads as a statement "If this AndAlso That then" If "This" if false
the "That" will not be evaluated. 
Of course equivalant in C# reads: "if This ampersand ampersand That brace".

IIRC (I'm a little hazy on this...), short-circuit logic was judged to be
too confusing by VB.NET programmers. And it *can* be confusing if the
expressions being evaluated have side effects.

.NET totally supports short-circuit evaluation of logical expressions, this
is a language-specific issue.
