解决 .NET 项目中的 package 依赖项

Question

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 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 本身就做得很好。

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，但我很高兴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该问题，因为当 Logz.io 不接受向后兼容性时，至少需要 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！

Answer 2

发布后几分钟就理所当然地想出来了。 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 package 来说，解决冲突是必需的。 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" />
