Answer 1

最简单的解决方案是:

1. 卸载出现问题的项目的 .csproj 文件。

2. 在.csproj 文件末尾添加这个

   <Target Name="WorkaroundAppConfigPathTooLong"
     BeforeTargets="GenerateBindingRedirects">
     <PropertyGroup>
       <_GenerateBindingRedirectsIntermediateAppConfig>$(IntermediateOutputPath)$(TargetFileName).config</_GenerateBindingRedirectsIntermediateAppConfig>
     </PropertyGroup>
   </Target>
   

3. 保存并重新加载项目。重建。

您基本上是在要求 Visual Studio 缩短导致问题的中间应用配置文件的路径长度。
