In xamarin studio when I want to add exra properities to my ios app i would go to source section of the info.plist file and add whatever I want in there. But in Visual Studio I could not find that. Anyone has any idea?
What you can change in the info.plist in Visual Studio is very limited. Unless Xamarin provides better support for editing info.plist in Visual Studio, you're stuck with using Xamarin Studio, XCode or any other editor to edit the info.plist.
A word of warning when using Visual Studio to edit info.plist: If you manually made changes to info.plist, make sure you make a copy of it before changing anything from Visual Studio because it may overwrite your changes.
