下面是regestring模块（ModuleCatalog.xaml）的代码

问题：

当我从一个模块（安全）导航到另一个模块（维修）时，它将显示以下错误

重要提示：如果插入
第一行中的断点未命中任何内容
我尝试了以下内容： 1.我已将所有PRISM dll的localcopy设置为false

请一定要让我知道，如果你面临同样的问题，你有一个很好的解决办法。您的回答或建议将不胜感激。
我认为它的becoz ur xap文件不存在或格式已损坏。请从web项目中删除所有ur xap文件，然后逐个模块重建ur应用程序模块，然后尝试运行您的应用程序，因为ur xap文件不存在或格式已损坏。请从web项目中删除所有ur xap文件，然后逐个模块重建ur应用程序模块，然后尝试在模块项目中运行应用程序，您必须为所有Prism引用配置CopyLocal='false'，否则，在MainProject中，它应该是CopyLocal='true'。
它对我很有用。
在模块项目中，必须为所有Prism引用配置CopyLocal='false'，否则，在MainProject中，它应该是CopyLocal='true'。
这对我很管用。
有没有人有热情阅读上述问题；）谢谢阅读。您是否尝试过关闭

选项。有时，调试器可能会对文件的来源感到困惑。关闭该选项通常允许在任何地方设置断点。在Silverlight 4中经常发生这种情况（不特定于MEF或Prism）。。。所有SL调试都变为非活动状态。我进入web项目的属性，删除xap，保存并重新添加它。错误表明注册
