The best ever MSDN help page

User of Users Group

It hurts with loading and plenty more. Come on, there has not been, and I mean this from my C# ASP.NET cold feet, a Web project with more failures and broken links than: MSDN pre v1. MSDN v1. MSDN 2 MSDN #2 (pronounced not-see-Sharp-Too), whatever happened after 2 No wonder they are buying and trying to buy other Web companies.

That's the part I didn't get. :) I've become so accustomed to the incredibly poor quality of documentation coming from MS these days that I just assumed it was a well deserved snarky commentary. Quality documentation from MSDN - who knew?

I half-expected the "good" documentation to be added in the "community content section". BTW, you should write something there saying that documentation DID actually help you.

can it create SuperDelegates ?

Hmm, tickles the brain. I came close to using that method for some arcane 'very cool to have' feature I wanted to implement about a year ago. Right now it's just TMI.

Basically the cool thing about that page is that you can 'bind' the first parameter of the delegate, so in effect you can create 'composed' expressions.

Don't see where that greatly helps you, perhaps I'm missing a particular scenario as you can either pass another expression which converts to object (blewh) or you could just go and do composition with Func<T,..> No? If you want expression templates well, C# doesn't have them; they designed the tedium of C# compiler away with that signature :)

That's exactly my reaction. I was thinking "hang on - this actually looks really good. Why is he dissing it". Then I turned off auto-sarcasm and it became clear.

cheers, Chris Maunder

Yeah, it took me a minute to remember where the switch was.

Yeah that is pretty good. For once even their example code isn't unnecessarily convoluted and complex for no apparent reason (something they've always been guilty of). I like the redesign too (I've been avoiding MSDN for probably a year now at least).

Hey, I dont always rant! :) PS: I even took the time to explain to the author why I called her article 'Useless'.

Basically it lets you make curried functions (functions with 1 free variable). So imagine you have foo(a,b). Now you can say bar(b) = foo(1,b). And call bar(x), and foo(1,x) gets executed.

Maybe we should have a new rule for posting in the Lounge, as in all posts should be sarcastic?

That's an utterly brillant idea.

Sounds like something that Ms. Clinton would use.

Not sure what you're trying to do with it again but I think people are doing that without explicit CreateDelegate (should be "new delegate" construct generated by compiler) or whatever it was along the shorthand lines of: public static Func< T, Func<U, Z>> Curry<T, U, Z>(Func<T, U, Z> fn) { return new Func<Func<T, U, Z>, Func<T, Func<U, Z>>>( f => x => y => f(x, y))(fn); } if that makes any sense. Probably not what you want but you can split it up and use extension methods. It doesn't look good to me, because it is pure C# unreadable :)

leppie

That is exactly what I am saying :) But this way allows you to do it to languages that does not support that compiler construct, or programatically.

OK was that sarcasm? :)
