C# 2.0 Spec Released

An anonymous reader writes "Microsoft released the design specifications document for C# 2.0 (codenamed 'Whidbey') to be released early next year. New features of the language include generics similar to those found in Eiffel and Ada, anonymous methods similar to lambda functions in Lisp, iterators, and partial types."

    Whidbey is the code name for the next Visual Studio, not just C#.

    Maybe you want to take a look a mono.

  3. Re:Does C# have continuations? by Tom7 · · Score: 4, Informative

    You should get out more. There's a world of programming paradigms most people have never heard of, because they're still stuck using C-alike block structured OO languages.

    Continutions are, roughly speaking, a generalization of setjmp and longjmp in C. However, to have true "first-class" continuations they need to be objects that you can pass around, store in data structures, etc. In C this isn't true, because if you return from the stack frame that did the setjmp, the continuation is invalidated. Lisp has "call/cc", some implementations of ML have "calcc" (typed), and many scripting languages have it, because it's pretty easy to implement in an interpreted language.

    Continuations can be used to implement exceptions, user-level thread packages, "early exits" from recursive code, and other cool stuff.

  4. Re:moving towards bloatware or are these important by Sivaram_Velauthapill · · Score: 4, Informative

    Removing something is very difficult. In fact, it is not recommended (unless it is a serious flaw or bug). There may be millions of developers using a particular feature or programming technique that is "bad". If you go and remove it, it could adversely affect all these programmers and their existing code. This is one reason why companies don't really remove features. Backward compatibility in software is absolutely crucial (especially when you force developers to upgrade to new versions all the time).

    The best thing to do is to "phase" out the undesired feature by not recommending it, not featuring it prominently in books, shifting features into optional components that must be installed, etc.

    I know this isn't exactly the ideal way to do things but I see no other way. I mean, if I was responsible for Visual Studio (or C# specifications), I would not remove features. Who knows who is using a particlar feature?

    I've been using C# for about a year or so now. I started with Java, and made a clean switch to C# for a few projects that required it. I don't think that it will ever replace any of the three P languages, but is more targeted at taking Java down.

    I'm not a full-time developer, I usually develop some basic web applications to enhance some of the new solutions I implement for Systems Administration. My experience with it is limited, but I'll give you my pro's and con's:

    Pro's

    Easier access to IO - just try it in Java and see. It's much faster in C#

    Improved XML support - also a lot simpler in c#

    Not as many third party specifications to learn. I remember having to learn Struts, Ant, Tomcat, and then Sophia after learning JSP - what a pain in the ass.

    MSDN - The help system inside VS.NET is better than most languages' will ever be.

    Con's

    Not the best IDE in my opinon - IntelliJ smokes Visual Studio.NET in almost every respect(except for the help).

    Can't use it on Linux or BSD - my applications are bound to fail more frequently than an equivalent Java/PHP/Perl app running on a secure box.

    Most of the support I used to recieve about Java, Python, and other open source languages don't discuss c#. There just aren't the same amount of mailing lists, IRC channels, forums, to throw around C# ideas. The ones that do discuss it tend to cater to the Lowest Common Denominator.

    I have to resort to Visual Studio 6 in order to create desktop applications that run on everyone's machine. The .NET framework has been a hard sell for the enterprise I work in.

  6. Re:Why C# doesn't Totally Suck by krumms · · Score: 4, Informative

    come on, where are the real differences

    I thought the same thing. It's actually lots of little things that make C# nicer all 'round (in comparison to Java): Most pleasant for me is the fact that I can use enumerations without (a) declaring a new class/interface (b) placing a ridiculously long "public static final int" before EACH member of the enumeration and (c) being able to use the newly declared enumeration's new type name for parameters instead of just "int" - remember semantics?

    Integrating legacy shit is also a snap with C#. Sure, managed C++ is better, but have you tried doing the same thing in Java? Yuck.

    Lots of little things like this, IMHO, make C# better than Java.

    I hate the fact that Microsoft charges an arm and a leg for Windows/MSVS/everything. But I like C#.

    If only it was cross platform from the word go. Mono's nice, but the MSVS IDE is what keeps Microsoft/Windows up and above Linux as far as ease of development goes.

    Python's better than everything else anyway. *hides* ;)

  7. It's already there in Java 1.5 by blamanj · · Score: 4, Informative

    Enums have been added, generics have been added, automatic iteration in for loops have been added, et cetera. True, it hasn't been released yet (the first Java 1.5 betas are due next quarter), neither is Whidbey, and the JSRs have been out for some time, and the prototype compiler with generic support has been available for months.

    Who the hell is the ECMA?

    "Ecma International is an industry association founded in 1961, dedicated to the standardization of information and communication systems."

    Here is a list of their standards. It includes specs related to C, Ada, IDL, ECMAScript (JavaScript), C# and WSDL. Interestingly enough, Sun and Oracle are absent from their membership list.

    Why not an IETF standard?

    Hint: the "I" stands for Internet. What does C# have to do with the Internet?
