I’m currently working on a Chrome extension that inserts lists of relevant Stack Overflow questions into MSDN documentation. As part of this I needed a way of converting the IDs used for MSDN pages into the canonical names of classes and functions. For example, “zba0x2tx” maps to “system.console.writeline”. This can be done quite easily by loading the relevant MSDN page and extracting the information from the HTML.
I could have written a function to do it as part of the Chrome extension’s server-side code. However, I thought there was a (very small) chance that someone else might find such a thing useful, so I’ve released it as a separate web service.
