No resource found that matches the given name "Theme.AppCompat.Light"

Hi Xamarinians

I have upgraded the support library packages to v23. After that I am getting this error in the style.xml files

Error APT0000: Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light.DarkActionBar'. (APT0000)

Here is my style file

  <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowNoTitle">true</item>
....

I have to go back to the older version, any idea why is this happening?

Thank you
