问题
I've read Microsoft documentation about Push Notification Service that they are offering for Windows phones but there is no information about pricing. I've read somewhere that it is free to use max 500 notification per day/per application/per device and it is unauthenticated mode but there is also authenticated mode which has no daily limit and cost some money. Is that true and if it is, how much is price?
Also I am interested in information about saving messages in server if user is not active in time of sending. How much push messages can Microsoft Push Service save for one device/user before starts to discard it?
回答1:
It is free, authenticated or not.
Not sure if they actually store messages on the server to be delivered. When you send one they will give you the clients connection status as part of the response.
