每隔一段时间，我就会在 Blend for Visual Studio 中遇到编译器异常。一切都在编译和工作，然后突然 BAM！我收到编译器错误，告诉我对象在特定命名空间中不存在时。在它们离开之前，我必须花一个小时进行清洁和重建以及关闭和重新打开 Blend。我的图书馆都是最新的，一切都很好。没有其他人有这种情况发生在他们身上吗？拜托，我希望它停止它是一个巨大的时间杀手。
我在 Visual Studio 中也遇到了编译器错误。
谢谢。
更新
例如，
错误 5 XML 命名空间“ http://schemas.microsoft.com/expression/blend/2008 ”中不存在属性“DesignWidth” 。第 15 行位置 5。C:\MyPath\MyControl.xaml 15 5 EasyBuilder
据我所知，DesignWidthis 确实存在于该命名空间中。
XAML（不是说它会帮助你）
