自定義 MSBuild 任務 .NET 6.0 使用 dotnet 運行，但不在 VS 中運行

Question

我有一個簡單的項目，它有一個自定義 MSBuild 任務。 此任務將使用 dotnet msbuild 運行，但通過 VS2022 失敗。 除了與 .NET 6.0 引入的架構有關的一些問題外，我沒有在網上找到任何東西，我認為這些問題不適用於此。 我認為鑒於 dotnet cli 將毫無問題地構建它，我一定會遺漏一些東西，唯一的問題是什么？

<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 文檔解釋說，由於 Visual Studio 正在運行.Net Framework，因此從 Visual Studio 中運行的任務應針對 .NET Standard 2.0，請參閱https://docs.microsoft.com/en-us/visualstudio/msbuild/tutorial-custom-task-代碼生成？view=vs-2022

在最壞的情況下，您可以構建一個控制台應用程序並使用內置的 Exec 任務運行它。
