It is a general purpose programming language, and can be used for (almost) anything. It can be used for networking programs, and it is often used for GUI programming.

So is it just like C++
As very brief summary yes. There are many small differences. The biggest one is that the memory management is done by the "language" itself, and that it's not a native compiler - it generates .Net code, which is the same concept as Jave ByteCode, not pure machine-code. It then uses clever techniques to translate this into actual machine code when you run the app - as far as I understand.

Well, it is clearly based on C++. So it is more modern than C++. But C++ is a better choice when you want something to run faster. It has offers more management it is an evolution from C, meaning speed is always a must for the language. Not that C# is slow. Well, google C# vs C++ and you will find a lot of opinionsQuote:

It is created by Microsoft and uses the .NET framework. Meaning that if a PC doesn't have the framework it cannot run the program. Of course installing the framework in Windows is free and simple. It can be done (they say) in Linux or some Linux.
As far as I know you can use the .NET library also with C++, but it will be probably better to do it with C#.
.NET / ASP.NET is really create for a GUI or a Internet based program. C++ is better when speed is an issue, like creating a game.
P.S1: I prefer C++, but that is because I like C.
P.S2: I played DMC 3 and 4 mostly to see the scenematics with Dante. There awesome. Probably the best is the Intro of DMC 3. Though that's also the first one so it's the first impression. From DMC 4 I liked the theatrical/drama scene most... and... wait this is a C forum....

C# iz a fansee wurd for java 4 microsoft.
Except that C# is .NET, as much as .NET is C#. It's bytecode compiled and runs on a virtual host, and cannot be compiled to a binary by itself(You get what I mean - it isn't the binary code itself the binary that gets made consists of).Quote:

Anyway it certainly does have it's place, although I'd pick Java over it anyday. What's the point of a managed, interpreted language if it's hardly portable?!?
If you really don't know how to spell properly, then I pity you. However, if it is by choice that you construct your sentences that way, don't expect to get any respect or useful help from normal people. if you want people to take you seriously, please conform to the same standard of spelling, sentence structure, and punctuation that everyone else has adopted. What do you think a potential employer would think if you wrote that way in your resume? they would read the first sentence and throw it in the trash can. Posts on this board are just as easily discarded or ignored.Quote:

anyone who says that C# is just a java knockoff doesn't know anything about the language. figure out who the language creator is and you'll learn where its real roots are!

Me? The only thing I have said favoring C# over C++ is that it is more Object Oriented, which is a good thing for an OOP language. Which also a lot disagreed.Quote:

The languages are too similar anyways too really favor one from another.
Yes, you. I only see C# threads from you, so I figured you have been all the rage about C# lately.Quote:

From my knowledge, it lacks such things as a lot of generic programming.
It also stuffs the garbage collector down your throat.
And, of course, it's way slower than C++ code.
So there are big differences in the language, methinks, and that makes C# inferior in my eyes.
C# has genericsQuote:

In pure data crunching, sure, but for an average application the difference is neglectable. Performance is affected more by choice of algorithms and the user himself than the coirce of language, unless you're writing low level drivers or state-of-the-art games.Quote:

And they are not just "evil" performance-wise, but when you really need control of your resources. C#'s GC tends to move things around if I'm not mistaken.
Of course, of course. For PCs, the performance cost is acceptable.Quote:

To me, that is not. Yet, even though it is negligible, it is a difference.
What C++ lacks are libraries for stuff... otherwise it could have been as much RAD as C# & Co.Quote:

It's a shame, really, I say :/
Not to mention the coalesce operator. Plain wonderful to work with, like when writing lazy properties.
WOW, I didn't know there was that op, I could have used that at work lol.
yes it does, for performance reasons. if you need to (like working with p/invoke) you can 'pin' memory in the GC which will prevent it from being moved.Quote:

Oops, sorry. The "correcting someone else bandwagon" is just so fun to ride though! Only when matsp isn't driving ;)
The JIT compiles the bytecode into machine code.Quote:

As such it's not an interpreter but a compiler, except of course that every compiler has to first interpret the code it's presented with in order to be able to compile it.
Does that make C++ an interpreted language? :D
No because C++ does it at compile time. There is a byte-code interpreter, thus technically it's interpreted and compiled. At least that's what they tell us in CS ;)
This discussion will get more heated when C# 4.0 introduces the "dynamic" type.
There are a lot of discussion about C++ templates VS C# generics. There is one on MS site also. Both have advantages/disadvantages. Generally templates can do a bit more than generics. But haven't use them excessively to understand how useful the "more" really is.Quote:
>>From my knowledge, it lacks such things as a lot of generic programming.

Maybe someone can shed more light on this?
Well as far as I understand you don't have in C# a way to do a specific implementation of a template class like you would in C++. I haven't created too many generic/templated classes to tell you the whole thing.
You talk of it as if it's a good thing. Generic programming should be generic, not introducing tons of special cases.Quote:

I think the main difference between an interpreted language and a compiled one is that the compiled language doesn't require the original source code to be run.Quote:

wow guys...all that over semantics of words...
anyways, C# 4 will definitely heat up discussions because it will cross the line between static and dynamic languages. although this has already been done previously with languages like Boo and IronPython for .NET, i think C# with microsoft's backing will make a big difference.
Here are the new features http://code.msdn.microsoft.com/csharpfuture
The dynamic sure looks interesting. And finally you can put default values on parameters. I am still wondering why this wasn't able from the beginning.
You had like 4-5 flags in a function and in order to avoid calling something with 20 arguments and mixing every time the flags, your only solution was to use oveloaded function wrappers to do your job, with a small cost of an extra function call. Finally, they saw their error.
yeah, default params are definitely needed, the strategy you had to implement was just annoying. Though allowing you to specify them out of order is kind of meh to me. I watched the PDC where you get a good illustration of what they are trying to do.
