WPF-Project System.Windows.Markup.XamlParseException

Question

我希望有人能帮助我。我有一个wpf项目(它工作得很好)，我想使用它在另一个。但是我得到了System.Windows.Markup.XamlParseException.

在:

<Expander IsExpanded="True"
                          Header="Symbols"
                          Margin="0,1,0,0"
                          Content="{StaticResource SymbolStencils}" />

我的SymbolStencils看起来像:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:s="clr-namespace:DiagramDesigner">
<s:Toolbox x:Key="SymbolStencils"
           DefaultItemSize="55,55">
    <ItemsControl.Items>
        <Button IsHitTestVisible="False">Button</Button>
        <ComboBox IsHitTestVisible="False" />
        <Label IsHitTestVisible="False" >Label</Label>
        <ListBox IsHitTestVisible="False" />
        <Rectangle IsHitTestVisible="False" />
        <TextBox IsHitTestVisible="False" >Text</TextBox>
        <TextBlock IsHitTestVisible="False" >Text</TextBlock>
        <RadioButton IsHitTestVisible="False" />
        <CheckBox IsHitTestVisible="False" />          
    </ItemsControl.Items>
</s:Toolbox>

<Window x:Class="DiagramDesigner.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:s="clr-namespace:DiagramDesigner"
    WindowStartupLocation="CenterScreen"
    Title="Diagram Designer Part 2"
    FontFamily="SegoeUI"
    Height="850"
    Width="1100">

那是我在XAML文件中的头
