Microsoft.NET.CoreRuntime的SOS调试扩展
在尝试使用WinDbg跟踪UWP C＃/ XAML存储项目中的致命空指针语言exception（c000027b）时，由于缺少Microsoft.NET.CoreRuntime的SOS调试扩展，我无法访问CLR Exception对象。 我无法找到匹配的sos.dll。 我错过了什么？
注意：应用程序崩溃是可重现的，但仅在未进行调试时才会发生。 因此，遗憾的是，在Visual Studio调试器下运行项目不是这种情况下的解决方案。

一个对BitmapImage的内部缓存机制有更多了解的人可能会对这种行为有所了解。 如果BitmapImage内部缓存开始运行，访问BitmapImage.UriSource.OriginalString可能会显然引发空指针exception，即使BitmapImage（Uri）与有效的Uri一起使用来构造BitmapImage对象也是如此。
我修改的序列化方法不再访问BitmapImage.UriSource.OriginalString，而是使用CastImage类的其他私有属性来维护该Uri。 问题解决了。
