I have been hunting the net for some time now and can't find something that demonstrates precisely what I am attempting to accomplish. Particularly, I've got a Native Android Application along with a wcf webservices website, that the android application may be the only consumer. Beginning out, the android application is really the only UI for that consumer, however, I am attempting to setup WCF web services around the back finish to complete certain data mapping and translations.

I realize that by establishing just one Facebook application and checking the web site and native android application entry ways, I am permitting the consumer to login to both UI and also the services after sales in a single fell swoop. However, things i do not understand is exactly what data I have to possess the application pass towards the services to have the ability to effectively authenticate the consumer. Will I must range from the auth token in the client to any or all demands towards the services?

OAuth is totally new in my experience in addition to Federated Identity. I am not a new comer to the .internet framework or webservices, but I am really battling with integrating the 2.

Does anybody have suggestions around the subject?
