Windows phone 7 VS Developer Express for Windows Phone新项目显示XamlParseException

我最近为windows Phone安装了windows 8和Visual Studio Express 2012。但是，如果启动一个新的Windows Phone应用程序项目（7.1，尽管8有相同的问题）并打开MainPage.xaml文件，则设计器窗口中会出现如下错误：

XamlParseException: Cannot find a Resource with the Name/Key PhoneBackgroundBrush [Line: 47 Position: 111]

        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"></Grid>
    </Grid>

</phone:PhoneApplicationPage>

MainPage.xaml文件如下所示：

XamlParseException: Cannot find a Resource with the Name/Key PhoneBackgroundBrush [Line: 47 Position: 111]

<phone:PhoneApplicationPage 
    x:Class="PhoneApp1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">

            <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"></Grid>
    </Grid>

</phone:PhoneApplicationPage>

App.xaml文件包含以下内容：

<Application 
    x:Class="PhoneApp1.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"       
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone">

    <!--Application Resources-->
    <Application.Resources>
    </Application.Resources>

    <Application.ApplicationLifetimeObjects>
        <!--Required object that handles lifetime events for the application-->
        <shell:PhoneApplicationService 
            Launching="Application_Launching" Closing="Application_Closing" 
            Activated="Application_Activated" Deactivated="Application_Deactivated"/>
    </Application.ApplicationLifetimeObjects>

</Application>

解决方案如下所示：

任何地方似乎都没有任何其他与样式相关的文件。有人能解释一下吗？它快把我逼疯了。

呸！修正如下：

XamlParseException: Cannot find a Resource with the Name/Key PhoneBackgroundBrush [Line: 47 Position: 111]

<phone:PhoneApplicationPage 
    x:Class="PhoneApp1.MainPage"

    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">

        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"></Grid>
    </Grid>

</phone:PhoneApplicationPage>

在右侧的“解决方案资源管理器”面板中的项目上单击鼠标右键 选择添加->现有项目 在文件浏览器中选择C:\Program Files（x86）\Microsoft SDK\Windows Phone\v7.1\Design\ThemeResources.xaml 单击“添加”按钮 在App.xaml文件中，添加以下内容并将该部分替换为：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="ThemeResources.Xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

在MainPage.xaml打开设计器-现在应该可以正常工作了。希望这能节省一些时间

根据您自己的答案，而不是复制原始主题。我将创建一个新主题，并将其与原始主题合并

创建一个新的资源字典（例如FixedDictionaryResources.xaml）。在VisualStudio中，您需要创建Windows Phone页面或使用任何其他创建XAML文件的模板。在Blend中，您可以直接创建资源字典。在VS中，您需要删除所有内容并放入以下代码。在混合中，只需添加

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <!-- Resource dictionary entries should be defined here. -->
    <SolidColorBrush x:Key="PhoneBackgroundBrush" Color="{StaticResource PhoneBackgroundColor}"/>
</ResourceDictionary>

打开App.xaml并添加以下代码以将新字典与默认资源字典合并

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Resources/FixingResourceDictionary.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

重新打开仍然显示PhoneBackgroundBrush丢失问题的页面，现在一切正常
