InvalidOperationException

An XmlReader asynchronous method was called without setting the Async flag to true. In this case, InvalidOperationException is thrown with the message “Set XmlReaderSettings.Async to true if you want to use Async Methods.”

This is the asynchronous version of ReadElementContentAsBinHex, with the same functionality. To use this method, you must set the Async flag to true.
