WP8 程序最小化后恢复报错 RRS feed

  • 问题

  • hi

    我这里有一个WP8应用不知道为何切换到后台以后再切换回来就直接触发Application_UnhandledException函数(我在App.xaml.cs中每个函数开头都下了断点,一个也没触发直接报错)

    Exception对象System.Runtime.Serialization.SerializationException,Message是这样的写的

    Type 'System.Windows.Media.SolidColorBrush' with data contract name 'SolidColorBrush:http://schemas.datacontract.org/2004/07/System.Windows.Media' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.

    HRESULT是-2146233076,堆栈全部都是外部代码,我也找不到切入口,堆栈如下
