    It definitely is. If you want to compare a JVM language to C#, try Scala. The Java language is so far behind C# it ain't even funny.

    Because the Java language, in a word, sucks.

    It's called Qt, not QT. And it's pronounced "Cute".

    It won't necessarily be slower. With a more modern language, you spend less time debugging stupid bugs than with C, which allows you to spend more time on optimization (or new features). This even applies if your preferred language is too slow for some part of the program: you can implement that part in C and do all the rest in a more productive language. Well, except that if you're using Java, you don't really what to do that, given the horrible PITA that JNI is.

    It's far behind in what? Then why people port C# applications to Java? And Java has much better GC. I read a little about Java and about C# and it looks Java is much more mature and solid while C# is more like a toy.

    Why? Except Java apps are slow (at least in my experience).

    I'm not pronouncing it here.

    Sadly (or not), every C# application I used is slow. People complain about F-Spot, Tomboy, because they're slow. Not only runtime is slow. If the Garbage Collector is a mess in Mono (and afaik it is) then there isn't a big chance to optimize the code, is there?

    In this thread there's a nice picture why some (probably many) users don't like Mono:

    Well Wine is not used in default install and is considered an emulator (even if it is not one) so it is not native...

    mono on the other hand is used by default in some Gnome based distros, and is considered to be native implementation of C# for linux...

    The big difference is also that mono will not let you run .NET apps without access to source code of the app and changing it and recompiling.
    Wine on the other hand runs exes (hence why most consider it an emulator)

    It's amazing how much misinformation is spread by some people in this thread. Probably has to do with this:

    I read a little about Java and about C# and it looks Java is much more mature and solid while C# is more like a toy.
    So you read a little? Nice.

    Here's some more reading material:
    1. Mono is using a tweaked version of the Boehm GC, which happens to be one of the best OSS garbage collectors in existence.
    2. Novell has been working on a faster, generational, Mono-specific GC since at least 2008 (just to give you an idea of what it takes to outperform Boehm). The new GC will ship with Mono 2.8.
    3. You can compile a C# app on .Net and run the exe on Windows/Linux/Mac. You can compile the same C# app on Mono and run the exe on Windows/Linux/Mac.
    4. Even though .Net/Mono binaries are have an 'exe' suffix, they are not win32 executables. No need to recompile and no need to emulate anything in order to run them on Linux.
    5. You can compile a Mono binary into native code. You lose the portability benefits of the .Net/Mono bytecode but you gain in startup performance and memory usage.
    6. If Mono is fast enough for Unity3d on devices as limited as the iPhone, then it certainly is fast enough for me.

    Mono is not worse than any other Microsoft product. It's an essential part of Windows emulation, to be run on top of Wine. Being interoperable with an organization is not wrong, and there are actually laws in place to facilitate it, if organizations are preventing it. Microsoft is helping with Mono, for whatever reasons, and that's nice.

    Using Wine or Mono to create Linux programs that have nothing to do with Windows compatibility, that's something I don't agree with. That's ripping off Microsoft. The free software community has access to interpreted alternatives such as Java, Qt, Python, Ruby, Perl, Vala, Scala, Haskell.

    Fake edit. Qt is not interpreted. And neither is Vala.

    What the hell is wrong with you guys?

    Let me rephrase your sentence:

    "Using [...] Java to create Linux programs that have nothing to do with Solaris compatibility, that's something I don't agree with. That's ripping off Sun"

    What the hell? I enjoy writing Linux applications. I also enjoy using C#. For this reason I enjoy writing C# Linux applications (that have nothing to do with Windows compatibility).

    You are saying this is bad... for what reason, exactly?

    I regard Sun as a Linux company. Look, it's the same as iPod clones. I won't buy a Korean clone. I will buy a Cowon.

    I'm just saying I don't agree with that. I won't be running that application.

    If Mono's GC is very good then Mono sucks even more, because Mono apps are damn slow Maybe developers who choose Mono are just lazy?

    @Blackstar

    If your interested some benchmarks show current Mono implementation of C# is much worse then Microsoft implementation:

    It also shows Java is usually faster.
