【问题描述】：

我有一个 .Net5.0 C# 类库项目，它构建得很好，但是在将目标框架更改为 <TargetFramework>net6.0</TargetFramework> 后，构建开始失败并显示以下错误消息：

现在即使将配置恢复为<TargetFramework>net5.0</TargetFramework>，问题仍然存在。请注意，我正在使用 Visual Studio 2019 并已安装 .Net6.0 SDK。这是csproj 文件：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Ben.Demystifier" Version="0.1.4" />
    <PackageReference Include="BundlerMinifier.Core" Version="3.2.449" />
    <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.6.1" />
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Authentication.AzureAD.UI" Version="2.1.1" />
    <PackageReference Include="Microsoft.Identity.Client" Version="4.30.1" />
    <PackageReference Include="Microsoft.IdentityModel.Clients.ActiveDirectory" Version="4.5.0" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.1.1" />
    <PackageReference Include="Newtonsoft.Json" Version="12.0.1" />
    <PackageReference Include="System.Runtime.Serialization.Formatters" Version="4.3.0" />
    <PackageReference Include="Synergix.WE.ComputerManagement" Version="2.4.34" />
  </ItemGroup>

  <ItemGroup>

更新：

包<PackageReference Include="Synergix.WE.ComputerManagement" Version="2.4.34" /> 是使用.netStandard2.1 构建的，当从引用中删除它时，错误消失了，但是由于内部依赖，构建失败，是否不可能在.net6 项目中引用.netStandard 库?

【参考方案1】：

解决方案：

1 - 将 TargetFramework 设置为 <TargetFramework>net6.0-windows$([Microsoft.Build.Utilities.ToolLocationHelper]::GetLatestSDKTargetPlatformVersion('Windows', '10.0'))</TargetFramework>

2 - 添加对 CsWinRT 到 <PackageReference Include="Microsoft.Windows.CsWinRT" Version="1.4.1" /> 的包引用
