After reading this I'll understand that C# generics really suck, big time, compared to C++ templates.
The constraints are really a pain in the butt, as you must specify what interfaces that the 'generic' type must implement, and not what specific methods of the interfaces that the generic type must implement. What you say, you may think: But if I wanted any type that has a method named 'void Print()' to be executed by my generic class, all of those types must implement a named interface (IPrintable). That is perhaps OK if I have full control over the source code, but whatif I'm using a library written by someone else?
If you don't specify a constraint the 'generic' type will effectivly be of type Object, and we all know how much we can do with the type Object. Hmm, let me think, oh yeah: ToString. No need for generics there.
The examples in the spec are also mostly container class examples, wonder why? Perhaps that the generics of C# can't do anything but (or mostly) container (or container like) classes.
Good thinking, sue Microsoft for the defects/bugs in their software. If you win the lawsuit (rather unlikely thinking of the size of Microsoft's legal department) you will open up a number of opportunities for people using Linux (or any other system for that matter) when they encounter a defect/bug. Think of the world when encountering a defect/bug will result in a paycheck of $10M, there would be a lot of millionaries in the world but no programs as noone would ever dare to publish anything.
Sure the boost syntax is a bit gnarlier, but not much. As on the flexibility of Qt it has a lot of limitations (http://doc.trolltech.com/3.2/moc.html).

Re:$1550 just to use it? No thanks.

Make that $4660 (a bit less if you're many) per developer (with Qt TrioPack, Enterprise Edition). TrioPack to have any use of the multi-platform capabilities and Enterprise Edition to use the QTable class.
And after that you'll have to pay $1450 (a bit less if you're many) per developer and year if you want any maintenance and support.

When are they dumping the Meta Object Compiler (moc) and switch over to Boost.Signals?
