Windows Phone 8: Localization doesn't work

Question

I have moved my application from WP7 (where I had no problems with localization) to the WP8. Now only English language is displayed regardless phone settings. My setup is (taken from http://www.geekchamp.com/articles/localizing-a-windows-phone-app-step-by-step ):

Resource folder content

• AppResources.en-US.resx [English]
• AppResources.pl-PL.resx [Polish]
• AppResources.resx [English]

WMAppManifest.xml:

<DefaultLanguage xmlns="" code="pl-PL" />
<Languages xmlns="">
  <Language code="en-US" />
  <Language code="pl-PL" />
</Languages>

Phone settings:

Answer 1

You also have to modify the main project file manually and add this:

<PropertyGroup>
        <SupportedCultures>en;pl</SupportedCultures>

You don't have to add your default language to SupportedCultures, see also here
