I am developing a chat app in c#.net using jabber, agsxmpp library and I want to make groupchat in it such as whatsapp groupchat and skype groupchat.

I came across persistent room in xmpp. Does it provides the functionality of permanent groups? and is it possible for a creator of the persistent group to add members without sending invites to them?

I searched the XMPP stuff on google, but nothing found clearly which room to use persistent, or should go with members only? if yes then please explain how.

XMPP groupchat is defined in XEP-0045: Multi-User Chat. The specification indeed define "Persistent Room", as "A room that is not destroyed if the last occupant exits; antonym: Temporary Room.".

I think however this is not what you mean as you refer to Whatsapp. In XMPP, MUC room are based on presence. It means you can only be in a MUC room if you have a session open and sent your presence to join the MUC Room. You cannot force a user to join a MUC room as only his client can send the presence to join.
