Why C# is hot... cool... whatever
-
The threading facilities in .NET are indeed :cool:. We have a C++ library that implements our TCP/IP socket communications, and a second that implements socket-based event logging, both used heavily in our distributed application. I replicated the functionality of both libraries in <2 weeks in C#. Of course, some of the ease in building the .NET versions of the libraries stems from the fact that so much of the stuff in the C++ libraries you get for 'free' with .NET.

I was looking at how to use a thread for background tasks and there is a BackgroundWorker in the toolbox list :cool:

Welll... yeeaah... but it doesn't belong in the toolbox, it doesn't appear on the form.

That's .NET Framework you are talking about, not C# :) Seriously, take a look at F#.
Do you think F# will take off next year or remain niche? My guess is that most developers will shun it because it seems too alien (personally I wouldn't shun it just because of that but developers are often surprisingly conservative).

My guess is it will remain niche. It is hard to learn and the benefits of using it are not obvious to most developers. But again, I've been wrong before :)

I had a brief look at Scala a while back and it seems more accessible, though that could be illusory because its syntax is more familiar.

The toolbox offers easy access to Controls (as in System.Windows.Forms.Control) and other Components (as in System.ComponentModel.Component), things one often needs, and having lots of properties. They include Timers, SerialPorts, BackgroundWorkers, etc. Dragging and configuring them through Designer makes sense to me. :)

The quality and detail of your question reflects on the effectiveness of the help you are likely to get. Show formatted code inside PRE tags, and give clear symptoms when describing a problem.

Interesting that you mention Scala in the same context as F#. I believe they play roughly equivalent role on their platforms. And I think they are both going to remain niche, although Scala probably has better chance of going mainstream because Java evolves slower than C# and VB so that may influence some Java developers to switch to Scala. On the .NET side, I am afraid we are going to continue enjoying the verbosity and clumsiness of C# and VB :)

One area where F# has some promise is in Scientific and engineering computations. The other area where I think F# might be useful is in the area of DSLs (Domain specific languages). I am currently investigating in my free time how to use F# for Financial modeling.

I all comes down to money. C# is cool and hot only because Microsoft has marketed it to developers that way. C# is just another slow, limited, buggy C++ clone without the .NET library. The .NET library could have been written almost 20 years ago as that's when a lot of those patterns you're loving so much were first written up and the community was catching on to their value. Mircosoft only did something that was new for them with C# and .NET, not something that was new to the developer community. Yes I use C#, every day in fact. Obviously, I'm not terribly impressed.

Now all they have to do is make MSDN work, so that it's easier to find this stuff out. :)

No kidding! I can usually find what I'm looking for on MSDN faster by using Google, and usually accidentally find better information on external blogs!

Yeah, but considering that Twitter runs on Apple stuff, it makes sense to that the fruit-fanatics would "think different" about how to create a mainstream web app. It also explains why their service so often displays "network too busy" messages when trying to simply login.

That's one of the advantages of .NET over C++, the rich framework. Yes I know you can achieve the same in C++ but you have to hunt harder. Though things may have moved on in the past four years which was when I last looked at C++.

Please do not confuse between .NET and C++; .NET is a framework, while C++ is a language. Also, C++ creates .NET.
I'm not confused. When you're using C# it's inseparable from the .NET framework, i.e., you have a rich library at your fingertips. With C++ typically you do not and either need to do all the stuff yourself or hunt around for disparate pieces.

So what? I'm not saying that C# is superior to C++, just that it has better "infrastructure" support for common problems. Naturally there are some scenarios where despite this C++ is a better choice.

I don't program much anymore but enjoy reading threads such as this as I still do a little C# .NET work. Your post caused me to wax nostalgic and recall how back in my early days when something didn't work the way you thought it would - due to bad or no documentation, or buggy program, or hardware failure (which used to happen quite often) - you had no Internet for help. Imagine no user forums. There were computer clubs whose members helped one another but when you're at a point that needs to be dealt with immediately, well, you know... There were published algorithms to do all kinds of sorts and searches and stuff, but there were no rich frameworks that generated the code for you. To make matters much worse there was always a memory and storage limitation to consider. Now if you need a fast file hash method just allocate some megabytes or gigabytes or, hell, terabytes. As for a development platform C# .NET is superb. As Ray Kurzweil's book title says: The Singularity is near. Mack McKinney

It's wonderful isn't it? The functionality at your fingertips these days is so rich that sometimes it feels like you can get 10 times as much done these days as you could a mere 10 years ago.

I remember purchasing a library of assembly language functions for the Commodore 64, which provided user interface functionality. That was the closest thing that I had to a framework back then. I would sit up all night, staring at code, printing out code and highlighting it, compiling over and over, making small changes to avoid a troubleshooting nightmare. It was almost an art form -- to try to fit the most functionality into the smallest amount of memory, using the smallest amount of processor power. Now, things are almost directly opposite. With all emphasis being on development time, optimization takes a back seat in most business-oriented applications. I still get a guilty feeling when I code something quickly, knowing that I could have done it more efficiently with just a little more time. But, that extra time could be spent on another project, and that's all that matters to the corporate bean-counters.

In the spirit of dispelling confusion, may I counter that C++ did not and does not "create" .NET.

It is either Assembly or C++ or a combination of both. Also, comparing C++ and the .NET family of languages is like comparing apples and oranges. C++ is a fully compiled laguage and you are totally free to do anything with it, including hang your self, where as, .NET languages are not fully compiled; they end up in bytecodes which are then interpreted by the .NET run-time when the application runs. Therefore, if your code is intended for speed in a extreme high trafic environment, such as real-time communication, C++ is your choice. Otherwise, for rapid app development, pick .NET. if you disagree, then please tell us what was used to create the .NET framework/.NET languager interpreters, or Java, or Javascript or all the other bytecode-oriented/managed codes/interpreters/the so-called "new languages" for that matter, that are being sold out there.
