C# is a disaster: takes the worst part of C++ (syntax) without inheriting its main strengths: static type system, RAII, performance, flexibility. The only good thing I can say about C# is that it is easy to learn if you already know C++ or Java. C# may be a good fit for web development (although web developers I know prefer even more dynamic languages, like PHP, Perl, VBScript, Python...) but for complex desktop apps and libraries it is a disaster. Even MFC is better, although I thought MFC was the worst thing ever - at least with MFC the applications can run fast enough. For the NLP libraries I work on, C# is a punishment: the stupid thing creates a new object on heap whenever a string needs to be changed (just don't mention the brain-damaged concept of StringBuilder), and in no time all the memory is gone and GC starts in the middle of processing. It makes Pentium 4 with 1G RAM crawl. Oh, and what about all this casting up and down? Geez, I learned 10 years ago that a cast is often a sign of an error in design - with C# you need to cast all the time. Anyway, I think I am done with C# for a while, and I am thankful for that. A horrible experience.

I meant Users. Of course we all strive for optimate performance, but most users don't want to pay 1000% overtime for a 100% performance gain. And I wouldn't even advice them to. Besides that, I don't think it's that easy to monitor a practical performance gain in a simple desktop app. The real bottlenecks are found in the DBMS and the network communication.

an integer is a value type (in .NET sense). this would mean that you can't change an integer. if you follow the same logic this should be illegal:
System.Drawing.Rectangle rc = new System.Drawing.Rectangle(5, 10, 15, 20); rc.Offset(1,2);if i can offset a rectangle this way, it should also be possible to do it inside foreach statement. -
