windows phone 7 - WP7, WP8 How to set several ResourceDictionaries to use custom FontFamilies -

i want set custom fonts controls, if set font inside one resourcedictionary , use in styles works fine. approach not fine me, because need have font declarations in separate dictionary styles using them.

in app.xaml have made several resource dictionaries

<application ...>     <application.resources>         <resourcedictionary>             <resourcedictionary.mergeddictionaries>                 <resourcedictionary source="resources/resourceagencydictionary.xaml"/>                 <resourcedictionary source="resources/resourcecommondictionary.xaml"/>             </resourcedictionary.mergeddictionaries>         </resourcedictionary>     </application.resources>     .... </application> 

in resourceagencydictionary.xaml have myfontfamilynormal declaration

<resourcedictionary     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">      <fontfamily x:key="myfontfamilynormal">/gbagencycommon;component/fonts/fonts.zip#gotham book</fontfamily>     .....     </resourcedictionary> 

in resourcecommondictionary.xaml want use font family (myfontfamilynormal):

 <resourcedictionary ...>         <style x:key="mytextblockvaluestyle" basedon="{staticresource phonetextblockbase}" targettype="textblock">             <setter property="fontfamily" value="{staticresource myfontfamilynormal}"/>             ....         </style>  </resourcedictionary> 

the project compiles runtime error

system.windows.markup.xamlparseexception occurred _hresult=-2146233087 _message=cannot find resource name/key myfontfamilynormal

does know how can fix that?

sorry guys, searched solution lot in internet , found it. solution simple (i've tried wrong path file , didn't notice right direction)

so in app.xaml

<application ...>     <application.resources>         <resourcedictionary>             <resourcedictionary.mergeddictionaries>                 <resourcedictionary source="resources/resourcecommondictionary.xaml"/>             </resourcedictionary.mergeddictionaries>         </resourcedictionary>     </application.resources>     .... </application> 

the resourceagencydictionary.xaml same

in resourcecommondictionary.xaml

 <resourcedictionary ...>          <resourcedictionary.mergeddictionaries>             <resourcedictionary source="resourceagencydictionary.xaml"/>         </resourcedictionary.mergeddictionaries>          <style x:key="mytextblockvaluestyle" basedon="{staticresource phonetextblockbase}" targettype="textblock">             <setter property="fontfamily" value="{staticresource myfontfamilynormal}"/>             ....         </style>  </resourcedictionary> 

note: source="resourceagencydictionary.xaml" because file in same folder resourcecommondictionary.xaml
