Interview Questions: Is IDisposable hard to understand? [closed]

Question

I've been interviewing a lot of .NET programmers lately and I haven't met one that knows what IDisposable is or what it is used for. Is it really unreasonable to expect someone with 4-6 years experience to know that?

Answer 1

Nope, sorry. If they don't know IDisposable, they don't understand object lifetime in .NET, so it's safe to assume that they have no idea how GC works. For someone who claims 4-6 year experience, he's either a "drag-and-drop" developer, or a liar. Either way, no hire.
