c# - 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。我们最近签署了该应用程序，现在我在启动时获得了很多第一次机会异常(exception)。我已将问题追溯到以下几点:

在任何 View 中，如果我在初始化 View 时在应用程序中引用另一个 namespace ，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"

它总是在寻找比我实际运行的版本低 1 的版本。

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

查看:

<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 中，然后通过该 DLL 引用它们，则没有问题。错误消失了。此外，如果我不签署应用程序，我不会收到错误。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。在创建所有 View 时，它还花费了大约 30 秒来抛出所有这些错误，因此我对性能造成了影响。我不明白为什么该应用程序要尝试加载自身，以及为什么它要尝试加载其自身的旧版本。无论我构建多少次，错误总是落后 1 个版本。

Answer 1

编辑:

您是否使用 ProcessMonitor 查看 Visual Studio 从何处加载 v 3.0.5917.24348？ Visual Studio 需要 v3.0.5920.15596，因此您必须将该 DLL 放在预期的位置。

编辑 2:

Can you put in a binding redirect in your config file like this?

<dependentAssembly>
 <assemblyIdentity name="xxxxxx" publicKeyToken="121fae78165ba3d4"/>
 <bindingRedirect oldVersion="3.0.5920.15596" newVersion="3.0.5917.24348"/>
</dependentAssembly>

引用:.Net picking wrong referenced assembly version

原文:

您可能会收到错误的一个原因:

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.

当您的程序集已签名并且您对它的引用将特定版本属性设置为 True 时，会导致 FileLoadException。

检查您是否将特定版本设置为 False:
