log4net 包依赖问题 - 版本 2.0.9.0 和 2.0.12.0

Question

在将 Logz.io log4net 插件 (Logzio.DotNet.Log4net) 添加到我的 .NET 项目后，我遇到了问题：

log4net:ERROR Failed to find type [log4net.Layout.SerializedLayout, log4net.Ext.Json]
System.IO.FileLoadException: Could not load file or assembly 'log4net, Version=2.0.9.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)

   at System.Type.GetType(String typeName, Boolean throwOnError, Boolean ignoreCase)

   at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.CreateObjectFromXml(XmlElement element, Type defaultTargetType, Type typeConstraint)


log4net:ERROR Failed to create object to set param: layout
log4net:ERROR Could not create Appender [LogzioAppender] of type [Logzio.DotNet.Log4net.LogzioAppender, Logzio.DotNet.Log4net]. Reported error follows.
System.IO.FileLoadException: Could not load file or assembly 'log4net, Version=2.0.12.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)

   at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.ParseAppender(XmlElement appenderElement)

简而言之，[log4net.Layout.SerializedLayout, log4net.Ext.Json] 请求 log4net 版本 2.0.9.0，而 [Logzio.DotNet.Log4net.LogzioAppender, Logzio.DotNet.Log4net] 请求 log4net 版本 2.0.12.0

所以在这种情况下，我清楚地理解了问题，但不知道如何解决它。我以前从未见过这种情况，通常，NuGet 自己做得很好。

理想情况下，让两者都使用 log4net 2.0.13.0 会很棒，这是本文发布时的最新版本，但我很乐意学习如何解决这个问题。

有什么想法或解决方案吗？谢谢！

Answer 1

更新到最新版本将解决问题，因为当 Logz.io 不接受向后兼容性时，需要最低 log4net 版本2.0.12.0。

几天前我也遇到了类似的问题，而大多数软件包在 ms vs 2022 最终版本之后都在更新！

在发布后几分钟理所当然地想通了。诀窍是信任 NuGet。不知何故，通过我的修补，我得到了混淆的版本。所以解决方案如下：

1. 右键解决方案->Manage NuGet Packages
2. 卸载log4net、log4net.Ext.Json和Logzio.DotNet.Log4net
3. 重新安装所有三个。 NuGet 将采用最新的兼容版本，正如@yasir-arafat 所提到的，至少对于 Logzio 包来说，它是解决冲突所必需的。最后，我可以确认以下配置（来自我的.csproj 文件）正在运行：

<PackageReference Include="log4net.Ext.Json" Version="2.0.10.1" />
<PackageReference Include="log4net" Version="2.0.13" />
<PackageReference Include="Logzio.DotNet.Log4net" Version="1.0.13" />

更新：如下所述，这并不总是有效。我试过这个app.config，但它不起作用：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-2.0.13.0" newVersion="2.0.12.0" />
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-13.0.0.1" newVersion="13.0.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>

如果我完全删除我的 docker 容器并且没有 app.config，我的项目似乎构建成功。

我正在继续调查。
