在 WinXP/WinServer2003 上从 xaml 设置图标时出现 XamlParseException？

Question

所以...很奇怪，我的Window 控件中有以下代码用于设置窗口图标，它在Win7 机器上完美运行：

  Icon="./Resources/MyWPF.ico"

在

<Window x:Class="MyWPF.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    
    xmlns:mdi="clr-namespace:WPF.MDI;assembly=WPF.MDI"
    xmlns:misc="clr-namespace:MyWPF.Tools.Misc"
    xmlns:View="clr-namespace:MyWPF.View"
    xmlns:ScriptListView="clr-namespace:MyWPF.Tools.ScriptViewer.View"
    Title="Voysus System" WindowStartupLocation="CenterScreen" MinWidth="800"     MinHeight="600"            
    Icon="./Resources/MyWPF.ico"
    x:Name="_Root" Closing="_Root_Closing"> 

但是当它在 Server 2003 Standard x64/WinXP Pro 上运行时，都给我错误：

System.Windows.Markup.XamlParseException

我也尝试使用Icon="/MyWPF;component/Resources/MyWPF.ico"

但它也给了我同样的错误。

删除该行后，代码停止在 WinXP 和 WinServer2003 上抛出异常。

同样，这些代码在 Win7 中运行良好，并在窗口上正确显示了图标。

我曾经遇到过这种情况，因为使用了一个全彩色的高清图标，XP 客户端似乎无法正确处理它。减少了图标的颜色数量并且效果很好。
