签署应用程序时出现System.IO.FileLoadException

Question

我有一个遵循MVVM模式的WPF应用程序.我们最近签署了应用程序,现在我在启动时获得了很多第一次机会异常.我已将问题追溯到以下问题:

在任何视图中,如果我在初始化视图时在应用程序中引用另一个命名空间,我会收到错误:

"Could not load file or assembly 'MyApplication, Version=3.0.5917.24348, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)":"MyApplication, Version=3.0.5917.24348, Culture=neutral, PublicKeyToken=xxxxxxxxxxx"

它总是在寻找一个比我实际运行的版本落后1的版本.

如果我从视图中删除对其他命名空间的引用,InitializeComponent()则不会抛出错误

视图:

<UserControl x:Class="MyApplication.View.DiagnosticsView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:convert="clr-namespace:MyApplication.Converters"  <!--Causes error-->
             xmlns:behave="clr-namespace:MyApplication.Behaviors" <!--Causes error-->
             xmlns:controls="clr-namespace:MyApplication.UserControls"  <!--Causes error-->

如果我删除这些引用,并将我的转换器和行为移动到另一个DLL,然后通过DLL引用它们没有问题.错误消失了.此外,如果我没有签署该应用程序,我不会得到错误.我真的不想在不同的DLL中引用这些东西,看起来这应该可以正常工作.当所有视图都被创建时,它也会花费大约30秒来抛出所有这些错误,所以我的性能受到了冲击.我不知道为什么应用程序试图加载自己,以及为什么它试图加载自己的旧版本.无论我构建多少次,错误始终是1版本.

您是否可能尝试在 XAML 中使用强名称 URI 引用？例如，通过设置AssemblyPublicKeyToken项目文件的属性或修改 XAML 生成的代码隐藏？

如果您的 XAML 引用使用强名称并且您使用不断变化的版本，那么您的 XAML 最终可能会使用项目的先前版本，因为引用是之前生成的在构建完成之前的（并且设置新版本） ）。

要进行检查，请在目录下找到为 XAML 生成的内容obj并检查 Uris（例如~\obj\Debug\TestControl.g.i.cs）：

System.Uri resourceLocater = new System.Uri("/T_Signing;V1.0.0.0;76005ee8ffcf5f2d;component/testcontrol.xaml", System.UriKind.Relative);

URI 上方有完整名称和版本。然而，如果您没有强命名引用，则 uri 会更像：

System.Uri resourceLocater = new System.Uri("/T_Signing;component/testcontrol.xaml", System.UriKind.Relative);
