msg.XMucUser gives you the <x xmlns="http://jabber.org/protocol/muc#user"/> tag.
So you could check if this is not null. If its not null then its an invite.

The X object then has properties to access all the children, eg. GetInvites(9 which gives you an enumeration of the invites n this object. There could be multiple, but in most cases there is only 1.

msg.From is the room you get invited to.

you get the conference tag with the following code:

msg.Element<Matrix.Xmpp.Muc.Conference>();

then just use the properties of the object

you nust be in the room, then you can use mucManager.RequestMemberList which retrieves it.
