The Xamarin needs to develop easy controls, documentation and customization should be easy.

Had huge pain in full screen mode dynamically for all the devices.

Calendar with colors forced me to create a new custom control from 0.

To be stable with the controls if you make a tab control in one version should be the same in other versions also, not reinvent and change the wheel.

Easy and clear documentation. Forums all with lots of no one cares why it works int works on my machine stuff.

To new technology and has to get mature and stable. If you are not in the same versions of Xamarin in mac and windows it just not works properly.

Proper error message. I am getting an error like There were deployment errors. Continue. (Not run in administrative mode the vs 2015, closing the emulator or it was opened by other vs before, or you closed the emulator before finished the deploy) There are lots of errors like "aapt exited with code 1" that means there is some bad character in image or in files like -.... or files starts with number.

Also sometimes out of memory exception when loading images larger then 1mb or in android 4.2 larger than 300kb, even going lover to 100kb having problems in 4.2 android.

Proper editor for Xamarin.Forms is a must have if you want to develop. You can't see the design what you are doing with vs 2015.

Also designer is crashing all the time if i open multiple times and make some adjustments.
