People like this tend to be the type of developers that can make stuff work, but because they aren't curious they never really learn how things are put together and their lack of knowledge comes out in several ways. The most common one is wheel reinventions, because googling available wheels isn't something they'd ever think of. Another common one is writing very inefficient code because they don't understand what's under the hood.
The ignorance of static void main is a key reason why so many WinForm applications actually suck and why so many developers make the sad mistake of putting their user interface FIRST which has the knock on effect of making code reuse problematic. This is fine when people make utils but I have a very long experience of seeing companies struggle with this issue as their util grows into something more complex. The entry point IS important and if you're trapped in an IDE you suck. Go read pragmatic programmer the chapter: Wizards. You need to know how Wizards do their magic or you get burnt hard when the magic breaks.
