To give a little background: I am in the process of developing a new programing language that targets the CLR, called "Liberty". One of the features of the language is its ability to define "type constructors", which are methods that are e...
Is it a good practice to implement event handling through WeakReference if that event is the only thing holding the reference and that we would need the object to be garbage collected? As an argument to this: Folks say that if you subscribe to something it’s your responsibility to unsubscribe and you should do it. ...

My boss thinks the VS 2008 IDE Window Manager(autohiding, docking of Solution Explorer, Properties, etc) is the best thing since sliced bread. I can't find a control that resembles that functionality in the Toolbox. Is there a control like that available that you know of? Or should I go ahead and implement it myself? Btw, we're using...

To me the concept of "Gurevich Abstract State Machine" (formerly known as "evolving algebras") seems very promising to provide a solid fundation to systems behaviours. It could be what relational algebra is for databases: the underlying theoretic fundation. The most complete implementation, to my knowledge, is the Microsoft ASML languag...
