带有 Serilog 程序集的 .NET Standard 2.0 项目问题
Issue with .NET Standard 2.0 project with Serilog assembly
我有一个 .NET Standard 2.0 项目，它使用 Serilog 程序集来使用 serilog 进行日志记录，这里是项目文件：
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netstandard2.0</TargetFramework>
<AssemblyTitle>Logger</AssemblyTitle>
<Description>Client Web Logger</Description>
<AutoGenerateBindingRedirects>false</AutoGenerateBindingRedirects>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Win32.Registry" />
<PackageReference Include="SchneiderElectric.Software.SASigning" />
<PackageReference Include="Serilog" />
<PackageReference Include="Serilog.AspNetCore" />
</ItemGroup>
<ItemGroup>
<PackageReference Update="Microsoft.CodeAnalysis.FxCopAnalyzers" />
</ItemGroup>
<Target Name="PostBuild" AfterTargets="PostBuildEvent">
<Exec Command="SET _WWBinDir="$(ProjectDir)..\..\..\interfaces\bin$(ConfigurationName)$(PlatformName)"
MKDIR %_WWBinDir%
robocopy "$(TargetDir) " "%_WWBinDir%" InSightLogger.dll /ZB /NJH /NJS /NDL /NFL /NC /NS
:END
exit 0
" />
</Target>
我的解决方案中还有另外两个项目，一个在 .NET 6.0 中，另一个在 NET Framework 4.8 中
这是 .NET 6.0 的项目文件：

对于 .NET 6.0，一切正常，但对于 .NET Framework 4.8，当我访问记录器项目静态 class 和方法时，它通过异常，这是我得到的异常

注意： 只有一件事我注意到我创建了 netstandard2.0 项目并且在日志中提到 netstandard 2.1.0.0 正在搜索，但无法理解。
通过仔细调查您的项目文件，我了解到您使用的是 dotnet standard 2.0，但错误地从 dotnet standard 2.1[=14= 搜索] 所以你需要验证所有使用包版本的项目并使用合适的版本。
