Question

I'm trying to invite guest to google calendar using GData. I found

http://www.mail-archive.com/[email protected]/msg01759.html

But on the line:

entry.ExtensionElements.Add(fragment.FirstChild);

I get a compile error saying:

Error 3 Argument 1: cannot convert from 'System.Xml.XmlNode' to 'Google.GData.Client.IExtensionElementFactory' 

What am I missing?

Answer 1

I solved it myself:

entry.ExtensionElements.Add(new XmlExtension(fragment.FirstChild));
