C# 2.0 Spec Released

Posted by michael on from the most-anticipated-new-language-of-the-week dept.

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."

  1. Why C# doesn't Totally Suck by Pflipp · · Score: 5, Interesting

    OK so I'm in the position of having to write an emergency support application for a M$-based system in a M$-based environment. Stuck in there. Completely. Been requested to make a maintainable, manageable solution. And yes, this is to say "make it for M$, with M$ tools as much as you can".

    I guess even within these circumstances, I'd have refused to open Visual Studio for this project, if it didn't say ".NET" as well. I mean, think of it: previous versions of VS only supported C++ or VB, with APIs to cry for (admittedly, I don't know about MFC, only about Win32).

    I actually happen to dislike C++, but on top of that, it doesn't suit my project, because the low-levelness makes it harder to program without errors (e.g. null pointers, memory leaking). I'd rather have a language at a scripting level -- and NO, that's NOT VB. I hope I don't have to explain why I hate VB if only on very first sight.

    So with .NET, M$ introduced a quite nice API and Java language (come on, where are the real differences) into Visual Studio, which at least saved my day; I had found an acceptable programming environment for within Windows..!

    There's really no need for anybody to pick on C#, long as it's realized that it's just finally a nice programming environment for Windows, and nothing (well, not much) more. (BTW, it's not much different from NeXT (now Apple)'s use/ takeover of Objective C.)

  2. C# generics on built-in types do not use boxing... by truth_revealed · · Score: 4, Interesting

    From the C# 2.0 spec:

    "When an instance of Stack<int> is created, the native storage of the items array is an int[] rather than object[], providing substantial storage efficiency compared to the non-generic Stack. Likewise, the Push and Pop methods of a Stack<int> operate on int values, making it a compile-time error to push values of other types onto the stack, and eliminating the need to explicitly cast values back to their original type when they're retrieved."

    Java uses Object boxing for built-in types in their generics implementation.
