VS2015通用项目无法识别LocalizedStrings

Question

I'm trying to convert a WP8 projet to Universal Apps. I'experiecing a strange error regarding LocalizedStrings.

I use Multilingual App Toolkit to manage translations. I've updated to the latest version (4.0) which says it supports Universal apps.

The thing is it gives me this error in App.xaml: The name "LocalizedStrings" does not exist in the namespace "using:StayfilmUniversalApp".

And it is complaining on the MainPage.xaml too but not in other pages... In MainPage.xaml it says that The type LocalizedStrings was not found. underlined in color blue the whole DataTemplate block that has a component which uses LocalizedStrings, for eg.:

<DataTemplate x:Key="TIT_WhatsNew">
        <Grid Width="250" Height="52" Margin="0" HorizontalAlignment="Left">
            <Rectangle Fill="White" HorizontalAlignment="Left" Height="3" Margin="0" VerticalAlignment="Top" Width="250" />
            <TextBlock HorizontalAlignment="Center" TextWrapping="Wrap" Text="{Binding LocalizedResources.WHATSNEW, Mode=OneWay, Source={StaticResource LocalizedStrings}}" VerticalAlignment="Center" FontSize="21.333" FontStretch="ExtraCondensed" FontFamily="/Assets/Fonts/Frontage-regular.otf#Frontage Regular" />
            <Rectangle Fill="White" HorizontalAlignment="Left" Height="3" Margin="0" VerticalAlignment="Bottom" Width="250" />
        </Grid>
    </DataTemplate>

here is my App.xaml:

<Application
x:Class="StayfilmUniversalApp.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:StayfilmUniversalApp"
RequestedTheme="Light">

<Application.Resources>
    <ResourceDictionary>
        <!--<local:LocalizedStrings x:Key="LocalizedStrings"/>-->
        <local:LocalizedStrings xmlns:local="using:StayfilmUniversalApp" x:Key="LocalizedStrings" />
        <Color x:Key="PhoneDisabledColor">#66FFFFFF</Color>
        <SolidColorBrush x:Key="PhoneDisabledBrush" Color="{StaticResource PhoneDisabledColor}" />
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Styles\PhoneStyles.xaml" />
        </ResourceDictionary.MergedDictionaries>
        <!-- Other resources if you have -->
    </ResourceDictionary>
</Application.Resources>

and My LocalizedStrings.cs:

using StayfilmUniversalApp.Resources;

namespace StayfilmUniversalApp
{
    /// <summary>
    /// Provides access to string resources.
    /// </summary>
    public class LocalizedStrings
    {
        private static AppResources _localizedResources = new AppResources();

        public AppResources LocalizedResources { get { return _localizedResources; } }
    }
}

Answer 1

The problem has nothing to do with LocalizedStrings.

I gave up trying to fix the page and decided to recreate it from scratch. Doing so, I found out there may be a VS bug behind and is showing different error. because when I added a DataTemplate (this one below) to a HubSection it gave me this error on the entire DataTemplate block: Cannot add instance of type 'Windows.UI.Xaml.Setter' to a collection of type 'Windows.UI.Xaml.SetterBaseCollection'.
