An XmlDictionaryWriter method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.”
The contents of the stream provided by the IStreamProvider are written as Base64 data, unless this method is overridden in a derived class.
For the asynchronous version of this method, see WriteValueAsync.
