C# From a Java Developer's Perspective
Microsoft's C# has raised eyebrows, interest and debate since its official announcement last year. The prolific Carnage4Life (Dare Obasanjo) has completed a detailed comparison of C# and Java, outlining the things that are identical, similar, nearly the same, or completely different between the two languages. If you're considering learning or applying either one, you might benefit by reading this paper first. There are some other excellent comparisons to be found linked from the Open Directory Project as well.

I've been a Java programmer since JDK 1.0 came out, though I've really done most of my Java coding with server side servlet stuff since the GUI library has, and probably always will, suck the wanker.
.. C# and the .NET framework wins hands down.
I just recently picked up C# about a month ago. The learning curve from Java was pretty damn low, only with a few different naming conventions and new language constructs. Things such as indexers, delegates, and the like (all of which I feel are positive additons to the language.) The event model, to my surprise, is better than Java.
Then after learning the language itself I started looking into Windows Forms and nearly spooged my pants. Finally Windows progammers get a clean framework of GUI controls with a powerful modern language behind it (ie, not C++ or VB.)
Usually if you wanted to make a powerful Windows app you were forced to use C++ since VB didn't really cut it. Now you can use C#. Complex Windows apps are going to be a whole lot easier to write now, nevermind the fact that they'll be able to do remote method calls via SOAP, and be deployed effortlessly (ie, create a Windows Installer in like 3 clicks or something.)
I have to say, for the stuff I'm writing that I don't need cross-platform compatibility (which I did surprisingly find to work in the case of servlets)

C# being better designed than Java is no big surprise. Why? Because Sun has done very little to further the actual language itself.
Java really hasn't changed much since its inception. All we have are a few more libraries, a GUI framework that blows ass, and a server-side framework that we didn't really need to begin with. But we have no real additional language FEATURES.
Like a lot of people, I've been using Java since the beginning. I look at the C# language and I see everything I want in Java. The great majority of differences between C# and Java are purely syntactical sugar -- compiler candy. AND THAT IS WHAT WE WANT.
We've been asking for support for generics and parametric types since JDK1.1. And they still aren't in (they were removed from 1.4 at the last minute). We've been asking for A REAL CONST. We've been asking for assertions -- and finally got them.
But all in all... most SEASONED Java developers aren't happy with the progress. Java has been plainly behind the curve when it comes to evolving new and different features. Instead, Sun poured all of their effort into their bullshit J2EE framework which is a complete shambles, IMHO.
Its obvious. Microsoft simply went to Usenet... read a bunch of Java posts... and saw that Java was stagnant. They took advantage of it. They created a new language... based upon Java... adding everything that Java developers were complaining about. Voila! C#!
I wonder if this would have happened if Java were open source. Probably not.
But one thing for sure... Microsoft is an EXPERT at catching a company while it is asleep at the wheel... ripping of its product... making it better... and seizing an entire market.
They just might be doing it again...
