Error when building Hello Xamarin.Forms Multiscreen

https://developer.xamarin.com/guides/xamarin-forms/getting-started/hello-xamarin-forms-multiscreen/quickstart/

위 예제의 CallHistoryPage.xaml 파일은 다음과 같다.

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:local="clr-namespace:Phoneword;assembly=Phoneword"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="Phoneword.CallHistoryPage">
    <ContentPage.Padding>
        <OnPlatform x:TypeArguments="Thickness"
                    iOS="20, 40, 20, 20"
                    Android="20, 20, 20, 20"
                    WinPhone="20, 20, 20, 20" />
    </ContentPage.Padding>
    <ContentPage.Content>
        <StackLayout VerticalOptions="FillAndExpand"
                     HorizontalOptions="FillAndExpand"
                     Orientation="Vertical"
                     Spacing="15">
            <ListView ItemsSource="{x:Static local:App.PhoneNumbers}" />
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

하지만 컴파일시 다음 에러를 발생 시킨다.

Error Failed to resolve assembly: 'Phoneword, Culture=neutral, PublicKeyToken=null' Phoneword.Android

 xmlns:local="clr-namespace:Phoneword;assembly=Phoneword" 를 다음으로 변경
 xmlns:local="clr-namespace:Phoneword;
