无法从Modulecatalog.xaml文件加载模块

Question

提前谢谢。

我正在尝试从XAML文件加载模块，但无法完成，我的xaml文件如下所示：

<?xml version="1.0" encoding="utf-8" ?>
<Modularity:ModuleCatalog
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:sys="clr-namespace:System;assembly=mscorlib"
  xmlns:Modularity="clr-namespace:Microsoft.Practices.Composite.Modularity;assembly=Microsoft.Practices.Composite">
    <Modularity:ModuleInfo
     Ref="ModuleAproject.xap"  
        ModuleName="ModuleA"
        ModuleType="ModuleAproject.ModuleA,ModuleAproject,Version=1.0.0.0">
    </Modularity:ModuleInfo>
    <Modularity:ModuleInfo
     Ref="ModuleBProject.xap"  
        ModuleName="ModuleB"
        ModuleType="ModuleBProject.ModuleB,ModuleBproject,Version=1.0.0.0">
        <Modularity:ModuleInfo.DependsOn>
            <sys:String>ModuleA</sys:String>
        </Modularity:ModuleInfo.DependsOn>
    </Modularity:ModuleInfo>
    <Modularity:ModuleInfo
     Ref="MyDemoApplication.xap"  
        ModuleName="MainModule"
        ModuleType="MyDemoApplication.MainModule,MyDemoApplication,Version=1.0.0.0">
        <Modularity:ModuleInfo.DependsOn>
            <sys:String>ModuleB</sys:String>
        </Modularity:ModuleInfo.DependsOn>
    </Modularity:ModuleInfo>
</Modularity:ModuleCatalog>

它抛出的异常是：

System.Windows.Markup.XamlParseException was caught
  Message=Cannot add content to an object of type 'Microsoft.Practices.Composite.Modularity.ModuleInfo'. [Line: 12 Position: 27]
  LineNumber=12

在这方面的任何帮助都是非常感谢的。我正在使用Prism 2.2和Silverlight 4.0进行开发

我已经很长时间没有使用Silverlight了，但是快速看一下你的代码，我认为你有以下错误

assembly=Microsoft.Practices.Composite

我相信在我的Silverlight项目中，我使用了以下内容

assembly=Microsoft.Practices.Prism

这是针对模块化命名空间的。如果这是不正确的，请让我知道，我会很乐意进一步帮助。
