The name “LocalizedStrings” does not exist in the namespace

Question

I\'m suddenly getting this error in my WP8 project, which seems to originate from generated code. I have a previous working version and the App.xaml is identical.

Answer 1

I had the same problem when compiling the standard Windows Phone Databound App template. Following steps worked for me:

• close all Visual Studio instances
• if your Region settings in the control panel mismatch the Windows Phone SDK's language (e.g. German), set the Format in the Region settings to English (United States)
• in your windows explorer, navigate to %LOCALAPPDATA%\Microsoft\Phone Tools\CoreCon\ and delete the contents of the folders 10.0 and 11.0
• reopen Visual Studio and rebuild your project

I also faced this issue. the root cause for my problem is as below.

1) I referenced below in my code. but i haven't added the library( System.Xml.Serialization.xml). Add Reference and select System.Xml.Serialization.xml to include the dll.

System.Xml.Serialization 

2) I use an usercontrol called FileList.xaml in the mainwindow

FileList.xaml

<AM:time2str x:Key="time2str"/>

But i didnt add the class which inherits from IMultiValueConverter

MainWindow.xaml.cs(I missed the following code)

public class time2str : IMultiValueConverter
{

    public object Convert(object[] values, System.Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        ********************
    }

    public object[] ConvertBack(object value, System.Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new System.NotImplementedException();
    }
}

I had this message when the mobile project platform was "ARM", I changed to "any CPU".

Go to:

• Solution Project / Properties
• Configuration Properties / configuration
• Click in mobile project / Platform / "Any CPU".
• Clean the project and run again

In my case I had this error after downloading and installing a fresh Visual Studio 2012 (the initial release version) and trying to build the default blank Windows Phone template project straight out of the box - it was only resolved by updating Visual Studio 2012 Express to Update 5.
