问题
好几个星期，它工作得很好，我能够编译和测试项目。几周前，当构建解决方案或任何不是分析器的项目时，VS开始显示以下警告:
Warning CS8032 An instance of analyzer Platform.Shared.Analyzers.Rules.StructuredMessageTemplateAnalyzer cannot be created from D:DevReposAzurePlatformsrcSharedAnalyzersPlatform.Shared.AnalyzersbinDebugnet5.0Platform.Shared.Analyzers.dll: Exception has been thrown by the target of an invocation
- 所有的库都在使用。net 5(也尝试过。net 6预览版，同样的警告)。
- 项目使用Directory.Build.props: 引用分析器。
<ItemGroup>
<ProjectReference Include="$(MSBuildThisFileDirectory)SharedAnalyzersPlatform.Shared.AnalyzersPlatform.Shared.Analyzers.csproj"
PrivateAssets="all"
ReferenceOutputAssembly="false"
OutputItemType="Analyzer"/>
</ItemGroup>
What I tried
- 16.10 VS。警告——
- 更新到VS 16.11。警告——
- 安装VS 17预览版(2022)并升级到。net 6。警告——
- PowerShell
dotnet build和dotnet msbuild。-无警告 - JetBrains骑手。-无警告
- Azure DevOps构建代理。-无警告
充分警告我启用了Fusion Log来获取完整的日志。从"错误列表"中(为引用分析器项目的每个项目的每个分析器生成一个分析器):

解决方案
作为临时解决方案，我在解决方案Directory.Build.props中添加了以下属性:
<PropertyGroup Condition="'$(BuildingInsideVisualStudio)' == 'true'">
<!-- Visual Studio compiler displays the CS8032 warning for unknown reason. Removing it manually to declutter the Error List -->
<NoWarn>$(NoWarn),8032</NoWarn>
</PropertyGroup>
我以前见过这个问题，它发生是因为你使用。net 5.0作为源生成器项目。源生成器的项目必须只有。Net standard 2.0根据这里的文档
