Xamarin Build Error: 'Resource.Attribute' does not contain a definition for 'actionBarSize'
<p>I'm currently trying to build the Hello World app from Xamarin. Each time I try to run or build it i get the error which you can see in the titel. I searched for quiet a time now but didn't get any solution on how to fix this. Maybe you should know that I'm new to Xamarin. Does anybody know how to fix this?</p>

<p>Many thanks in advance</p>
