HRESULT:Windows Phone编程中的0x80270254

Question

我在获取visual studio 2013时遇到了麻烦.每当我为Windows Phone 8.1应用程序创建新项目时,MainPage.xaml都能正常运行,直到我重新启动或关闭我的笔记本电脑.但是,当我打开我的笔记本电脑并尝试打开现有项目时,MainPage.xaml无法加载.它说

System.Runtime.InteropServices.COMException
This app does not support the contract specified or is not installed. (Exception from HRESULT: 0x80270254)

这是完整的错误详细信息.
