Before explaining what apartments are let’s think about classes and objects regardless of COM. When you build a class, you know (or you should) whether objects of that class will be used from a single thread, … Read more

This is a great book about designing user interfaces, with examples of bad and good ideas. I’m getting the printed version and I recommend this to all building UIs. Now, yesterday I had a problem with … Read more
