A new event is constructed with an initial count (retrievable with the I n it i a l C o u n t property), and its current count is initialized to that (also retrievable afterward, with the C u r r e n t C o u n t property) Then threads call D e c r e m e n t to subtract one from the current count Any number of threads can wait, and they will be blocked until the event's count reaches O At that point, I s Set will report back true You can R e s et the event, which (by default) unsignals the event and changes its current count to the initial count (or the count specified as an argument to R e s et if you so choose) The event is backed by a lazily alloca ted Win dows kernel event, so it is a good idea to call D i s po s e on it when you're done

Lazyl nit<T> As we saw in 1 0, Memory Models and Lock Freedom, lazy initiali zation of program data is a common need that is often solved by the double-checked locking pattern This pattern is not completely obvious and has been subject to a lot of misunderstanding in the past due to the weaker NET ECMA memory model And at the very least, it turns out to be complete boilerplate The S y s t e m T h r e a d i n g L a z y l n it < T > value type is a really simple, lightweight data structure that abstracts away all of these things
