The Universal Device Detection library for .NET that parses User Agents and detects devices (desktop, tablet, mobile, tv, cars, console, etc.), clients (browsers, feed readers, media players, PIMs, ...), operating systems, brands and models. This is a port of the popular PHP device-detector library to C#. For the most part you can just follow the documentation for device-detector with no issue. Instead of using the full power of DeviceDetector it might in some cases be better to use only specific parsers. If you aim to check if a given useragent is a bot and don't require any of the other information, you can directly use the bot parser.
