I work with .net in porfessional und at the university (part time study on software design, so I’ve still some years of proffessional expirience) we use java.

My personal preference is .net because i like the visual studio ide more than eclipse ide (but there are stille other ide’s for java so don’t hang up on this).

To take a look at the language features I think c# compared to java is nearly the same (both copy from both and both invent new features). With the next Visual Studio release Oracas und the .net 3.0 (and 3.5 that comes with Orcas) framework microsoft introduces a lot of new things but let time show whether this makes it more popular and even the more important thing to make it better. So for me there is no question that both platforms will be there in the future and both have their right to exist.

Maybe we should keep a bit more in mind that the platform should support us to get our job done und companys have to decide what’s best for their requirements. And yes of course both platforms are better on differnt requirements (what a suprise!). Nearly no one would use java to create windows client apps (no suprise too). On the other hand very broad band of server applications are written in java (for me no suprise too).

At least to bring in one fact of the populartiy of programming languages visist http://www.tiobe.com/tpci.htm. Here we see that java with 18% is the clear leader. But what i we also see in the long term trends is that java lost some of there market und “.net languages” gained some market shares. I hope that both plattforms would be the same popular. Competition is good for at least the end user and this in this case is us, the developers.

So folks it would be really nice to see a bit more harmony between the communities.

I work with .NET and Java. If you really learn .NET and compare it with Java objectively, you’ll will see why .NET is a good framework to work with.

If ASP.NET is annoying, try using JSF. BTW, where does JSF get it’s ‘code behind’ concept from.

The main point is ‘Do not let Java or you hatred with MS affect your judgment.’

 
Ahahaha. This tells you how seriously you should take this post.  I like Paint.net but it doesn’t even have soft paintbrushes.

Java and C# (the languages) are 90% the same. One is not massively more productive than the other. Java is slightly faster but not enough to worry about (plenty of people like ruby which is 10-30x slower)

The Java standard library is significantly better than the .NET one. Windows forms are a bit quicker than Swing but much less full featured as it is basically a thin wrapper on Win32. I don’t know how the Mono implementation is coming along but most Mono developers use gtk bindings instead. There is also the ever-present threat of legal action against Mono by MS.

90% of Open source libraries for .NET are ports of Java ones e.g. Nant, NUnit, Spring.NET.

JRuby is significantly better than the .NET Ruby implementations.

i think what we should consider how much you can do with each language.  i test myself and i have created a simple MDI photo-editing program using .net with brush/eraser/color selection/save tool for only 1 and 1/2 hours. is that possible in java? 

.Net thick client development targeted at Windows is of course far more productive on .Net – not surprising.

Visual Studio is complete crap. Without the Resharper plugin, it’s next to useless especially in terms of refactoring and intention support when compared to Eclipse and InelliJ. Even with Resharper, it still doesn’t quite match the power that the others put at my fingertips.

ASP.Net is a really annoying way to do web apps for anything which deviates from the ‘normal’ web application. I once had to go through all those auto generated pages stripping out all the HTML and leaving only the ASP tags – then go and rewrite all the HTML and CSS around them by hand. That said, this was on a VS 2003 and I’ll be the first to admit that VS2005 may have improved things.

Microsoft also has no support for ORM which has been around for years now. You still have to use NHibernate. OSS. Hurray.

Ultimately, if your application follows the flow that the .Net development environment enforces, you’ve hit the sweet spot and will be productive. But if you need to deviate, god help you, because you simply can’t mix and match portions of the stack like you can in Java.

“Java is an excellent and more-or-less efficient language. C# is just a bit more excellent in my opinion ”

The main problem with Neosmart is that Java folks are attempting a serious debate, backed up with citations (e.g. the performance comparison cited above). Most of the C# folks here are basing assumption upon assumption, based on opinions.

The whole article that sparked this discussion appears to be based purely on the opinions of the author, which seems to be based MS press releases and marketing. There is no evidence whatsoever of any credible research. It’s not that the article is written badly, it’s actually quite readable, the problem is that it makes many false assumptions about Java.  e.g. Java not being portable. Applications written with Java version 1.0 on Solaris (SPARC) in 1996 work without recompiling on a Windows or Linux system on x86 using Java 6.0 more than ten years later. I can only guess that the author has little interest in Java (his choice), and doesn’t really know much about it.

If Microsoft only released a redistributable (even if closed-source) framework for Linux and OS X, it would certainly become a much more productive venue.

There are some guys around who provide facts about Java vs .NET. And then there are MS fanboys who just don’t care about facts.

Give up the fight, if you want to have a reasonable discussion, go somewhere else, you won’t have it on this website  

Agreed. But surely that is rather obvious. If a brand new beautiful language came out tomorrow that everybody loved and wanted to write in, job counts would not qualify as a factor for language success for a very long time.

I take the the implication that your statement is about the future. What happens tomorrow is anyones guess. However, job counts very much qualify as a factor that a language has succeeded in the market.

Personally, I can’t see that .net has very much going for it over other solutions. Maybe I would be more interested if the source was available and I wasn’t locked into Windows (and don’t bother mentioning Mono, it will always have huge sections of functionality missing and/or out of date).
