wpf BenchmarkDotNet SimpleJob属性：如何指定与net6.0-windows等效RuntimeMoniker

我想在一个WPF类库中对类进行基准测试，该类库同时具有.NET 6.0和.NET Framework 4.8的多目标。下面是项目文件：
WpfClassLibrary.cs:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net6.0-windows;net4.8</TargetFrameworks>
    <UseWPF>true</UseWPF>
  </PropertyGroup>
</Project>

我想要测试的类，simple示例化了一个System.Windows.Documents.FlowDocument对象：

namespace WpfClassLibrary
{
    using System.Windows.Documents;

    public class WpfClass
    {
        public FlowDocument Document { get; } = new FlowDocument();
    }
}

下面是基准测试项目的项目文件：
BenchmarkingWpfClassLibrary.csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFrameworks>net6.0-windows;net4.8</TargetFrameworks>
    <UseWPF>true</UseWPF>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="BenchmarkDotNet" Version="0.13.7" />
  </ItemGroup>
  <ItemGroup>
    <ProjectReference Include="..\WpfClassLibrary\WpfClassLibrary.csproj" />
  </ItemGroup>
</Project>

基准本身：
Program.cs:

namespace Benchmarks
{
    using BenchmarkDotNet.Attributes;
    using BenchmarkDotNet.Jobs;
    using BenchmarkDotNet.Running;
    using WpfClassLibrary;

    internal class Program
    {
        static void Main(string[] args)
        {
            var results = BenchmarkRunner.Run<WpfClassBenchmarks>();
        }
    }

    //[SimpleJob(RuntimeMoniker.Net48)]
    //[SimpleJob(RuntimeMoniker.Net60)]
    public class WpfClassBenchmarks
    {
        [Benchmark]
        public void WpfClass()
        {
            _ = new WpfClass();
        }
    }
}

如果我按原样运行，基准测试就可以构建并运行良好。但是，如果我注解掉这两个SimpleJob属性，.NET Framework 4.8基准测试可以正常构建和运行，但.NET 6.0基准测试却不能。我得到以下错误：

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

我认为发生的事情是，当没有指定SimpleJob属性时，BenchmarkDotNet正在使用适当的net6.0-windows名字对象构建基准。但是，当将SimpleJob属性与名字对象RuntimeMoniker.Net60一起使用时，它将使用错误的net6.0构建。
如何指定使用net60-windows而不是net60的运行时名字对象的简单作业？

我认为你需要使用IConfig来编程实现这一点，即。不能直接使用SimpleJobAttribute：

internal class Program
{
    static void Main(string[] args)
    {
        var results = BenchmarkRunner.Run<WpfClassBenchmarks>(
            ManualConfig.Create(DefaultConfig.Instance)
                .AddJob(Job.Default.WithRuntime(ClrRuntime.Net48))
                .AddJob(Job.Default.WithToolchain(
                    CsProjCoreToolchain.From(
                        new NetCoreAppSettings(
                            targetFrameworkMoniker: "net6.0-windows",
                            runtimeFrameworkVersion: null,
                            name: "6.0")))));
    }
}

public class WpfClassBenchmarks
{
    [Benchmark]
    public void WpfClass()
    {
        _ = new WpfClass();
    }
}

或者使用命令行参数指定运行时：

internal class Program
{
    static void Main(string[] args)
    {
        BenchmarkSwitcher.FromAssembly(typeof(Program).Assembly)
            .Run(args);
    }
}

指令：

dotnet run --configuration Release --framework net4.8 --runtimes net6.0-windows net48 --filter *

虽然可以在配置as suggested by mm8中显式指定工具链，但如果进程以.NET 6.0运行，则默认的Job配置将自动识别并使用“net6.0-windows”名字对象。因此，以下也是可行的：

var config = DefaultConfig.Instance
    .AddJob(Job.Default.WithId("net60"))
    .AddJob(Job.Default.WithRuntime(ClrRuntime.Net48).WithId("net48"));
var results = BenchmarkRunner.Run<WpfClassBenchmarks>(config);
