edit 1:

in app.xaml in shared have:

<application     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >     <application.resources>         <resourcedictionary>             <resourcedictionary.mergeddictionaries>                 <resourcedictionary source="theme/styles.xaml"/>                 <resourcedictionary source="theme/other.xaml"/>             </resourcedictionary.mergeddictionaries>         </resourcedictionary>     </application.resources> </application> 

the issue need merge resourcedictionary directly inside other resourcedictionary, instead of including them both in app.xaml.
