As far as OEM notes go ms is probably among the best but it’s not saying a lot. I find that most MS notes rarely explain the how very well if at all. They usually just explain the what. Sometimes that is enough, but usually I want to see examples of how to use code to perform a task. For me at least seeing examples of real world use helps infinitely more than here is an object. Here are its public methods. Here are its public fields and properties.

Stack Overflow excels at showing implementation examples which, while the best way is not always highly rated, at least shows a way. When I was more junior I would sometimes take SO answers verbatim but I think now it at least gives me something to think about improving.
