自定义 MSBuild 任务 .NET 6.0 使用 dotnet 运行，但不在 VS 中运行

Question

我有一个简单的项目，它有一个自定义 MSBuild 任务。 此任务将使用 dotnet msbuild 运行，但通过 VS2022 失败。 除了与 .NET 6.0 引入的架构有关的一些问题外，我没有在网上找到任何东西，我认为这些问题不适用于此。 我认为鉴于 dotnet cli 将毫无问题地构建它，我一定会遗漏一些东西，唯一的问题是什么？

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net6.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>
    <ItemGroup>
        <PackageReference Include="Microsoft.Build.Utilities.Core" Version="17.2.0" />
    </ItemGroup>
    <UsingTask TaskName="PublishValidationTask" 
               AssemblyFile="..\bin\Debug\net6.0\ConsoleApp25.dll" />
    <Target Name="MyTarget" 
            AfterTargets="Build">
        <PublishValidationTask />
    </Target>
</Project>

using Microsoft.Build.Framework;
using Task = Microsoft.Build.Utilities.Task;

namespace ConsoleApp25;

public class HelloWorldTask : Task
{
    public override bool Execute()
    {
        Log.LogMessage(MessageImportance.High, "Hello World");            
        return true;
    }
}

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Microsoft 文档解释说，由于 Visual Studio 正在运行.Net Framework，因此从 Visual Studio 中运行的任务应针对 .NET Standard 2.0，请参阅https://docs.microsoft.com/en-us/visualstudio/msbuild/tutorial-custom-task-代码生成？view=vs-2022

在最坏的情况下，您可以构建一个控制台应用程序并使用内置的 Exec 任务运行它。
