Hello again, please can somebody advise me, how can i create crossplatform solution. 3 projects -> ios, android, core. In core, should be logic for pdf generator. I found at least 5 different libraries, but some working only for ios, some for android, some can work in both, but there is no support for system.drawing assemby etc...I think that this is not so extraordinary think, that developer want from xamarin. This should be basic feature for all platforms.
