Yes, that's a great start. I guess I used the wrong phrase. It's not driver's I'm interested in since most components require no drivers at all. The point is the coding libraries for controlling these things for a specific task -- Almost like code snippets. For example, switch debouncing. There's quite a few different libraries in Arduino and tons of debate on which to use based on your needs of granular control (including hardware used). However, like you pointed out, in .net 4.1 there's just the boolean parameter in the constructor for a InputPort. I suppose if there's a specific library defined for product X, it would be relatively trivial to port it to C#. Well, I'm going to get one and play around with it. Hopefully it can handle what I need without any issue. Any advice on how to keep pin state updates as fast as possible using the net framework? The idea of having multiple threads is scary. I have no idea how a microcontroller like this would handle it. Volatile comes to mind.
