Hi.. I have been building apps for 3 years using GM studio... and I am very tired of it being limited with it's sandbox features etc...
How is Xamarin in comparison? Does it have any limits or is anything possible?
Is it possible to for example create account systems such as "login with facebook", upload images and files to the app from the local device storage, or/even networking functions such as chat, online game battles etc...?
How is the learning curve for Xamarin? Is it easy to learn? Are there any good tutorial sources out there?
I presume it uses C++ as programming language?
EDIT: Is Xamarin Studio really free? Or are there hidden cost? Can I really develop a full app and publish it completely free??
