我刚刚下载了14个CTP版本的Visual Studio,并为Windows Phone创建了一个空白应用程序。我试图打开MainPage.xaml
,设计师会显示以下错误:
对于那些看不到图像的人:
System.Exception

Windows cannot install package App.a5cd6ef3c.a895b.a4508.a96fd.af1634c30bb13 because this package depends on another package that could not be found.

我输入App1.xaml.cs
和MainPage.xaml.cs
我已经看到 App 和 MainPage 分别没有{的定义{1}}。
该项目处于由Visual Studio创建的状态,我没有改变任何内容!
为什么会发生这种情况,我该如何解决?

今天也开始发生在我身上;要重现此问题,我只需打开Visual Studio 2013 Update 4,创建一个空白的Windows Phone 8.1并双击MainPage.xaml。
我通过执行以下操作解决了(我在网上看到的内容的混合):
使用管理员权限打开命令提示符并执行以下命令:
pushd %VS110COMNTOOLS%
icacls ..\IDE /grant *S-1-15-2-1:(OI)(F)
icacls ..\IDE /grant *S-1-15-2-1:(CI)(F)
icacls ..\IDE\PrivateAssemblies /grant *S-1-15-2-1:(OI)(F)
icacls ..\IDE\PrivateAssemblies /grant *S-1-15-2-1:(CI)(F)
icacls ..\IDE\PublicAssemblies /grant *S-1-15-2-1:(OI)(F)
icacls ..\IDE\PublicAssemblies /grant *S-1-15-2-1:(CI)(F)
最后,重启。适用于Windows 8.1 64位。

确保XAML上的类名与代码隐藏中的类名匹配。我在重构时遇到过这种情况。
XAML开幕标记:
<UserControl
x:Class="Namespace.Foo"
... />
代码背后:
public sealed partial class Bar : UserControl
{
public Bar()
{
// This will become the error specified (does not contain definition)
this.InitializeComponent();
}
...
}
所以Namespace.Foo需要在这里使用Namespace.Bar来摆脱错误。如果使用Page
而不是UserControl
,则应该具有相同的行为。

今天遇到同样的问题,通过杀死所有实例并再次打开来修复它。

它对我不起作用。刚创建了具有管理员类型的新本地帐户(Window 8.1,VS 2013 update 4)。通过新的本地帐户登录。打开并看到它已经解决了。
