Hi guys Smiley ,

I want to develop an app for WP but I'm still a noob. There are many apps out there on marketplace that retrieve data from websites, such as Weather Apps, Social Apps (Facebook, Twitter), Feed Reader Apps, etc. How are those apps get all the data and then send all the inputs, which users put in, back to the server?

Is it also the same process for desktop apps as well? Do you have any recommendation book for this kind of topic using C#?

Sorry, if my English is bad Embarassed.
