C# 如何将高度定制的TestServer设置从.NET Core 3.0升级到3.1

我有一个TestServer，它扩展了AspNetCore.TestHost.TestServer，作为.NET Core升级到3.1的一部分，我正在升级它，升级项目效果很好

<TargetFramework>netcoreapp3.0</TargetFramework>

netcoreapp3.0

但是，一旦我将Microsoft.AspNetCore.TestHost从3.0.0升级到3.1.x，我的测试就会在无限循环中运行。 我已尝试将我的TestServer转换为新设置，如下所示： 但是我们有太多的扩展和定制，很难翻译。 我怀疑问题在于我们的模拟程序读取非常大的json文件

TestServer如下所示：

public class MyTestServer : TestServer
{
    private MyTestServer(IWebHostBuilder builder) : base(builder)
    {
        TestHelperSettings = UriTestHelperSettings.Default;
    }

    public UriTestHelperSettings TestHelperSettings { get; }

    public static MyTestServer Create<TStartup>() where TStartup : class
    {
        var builder = new WebHostBuilder()
            .ConfigureAppConfiguration((context, config) =>
            {
                config.AddJsonFile("appsettings.Test.json", false);
            })
            .UseStartup<TStartup>()
            .UseEnvironment("Development");

        var testServer = new MyTestServer(builder)
        {
            ApiExporer = UriTestHelpers.ApiExplorer
        };

        return testServer;
    }

    public IApiDescriptionGroupCollectionProvider ApiExporer { get; private set; }

    public static MyTestServer Create() => Create<TestStartup>();
}

    public class MyTestServer : TestServer
{
    private MyTestServer(IWebHostBuilder builder) : base(builder)
    {
    }

    public static TestServer Create<TStartup>() where TStartup : class
    {
        var builder = new HostBuilder()
            .ConfigureAppConfiguration((context, config) =>
            {
                config.AddJsonFile("appsettings.Test.json", false);
            })
            .ConfigureWebHost(webHost =>
            {
                webHost.UseTestServer();
                webHost.UseStartup<TestStartup>();
                webHost.UseEnvironment("Development");
            });

        var host = CreateHost(builder);
        TestClient = host.GetTestClient();
        host.GetTestServer().AllowSynchronousIO = true;
        return host.GetTestServer();
    }

    public static IHost HostWeb { get; set; }

    protected static IHost CreateHost(IHostBuilder builder)
    {
        HostWeb = builder.Build();

        HostWeb.Start();
    
        return HostWeb;
    }

    public static UriTestHelperSettings TestHelperSettings => UriTestHelperSettings.Default;

    public static IApiDescriptionGroupCollectionProvider ApiExporer => UriTestHelpers.ApiExplorer;

    public static TestServer Create() => Create<TestStartup>();

    public static HttpClient TestClient { get; set; }
}

公共类MyTestServer:TestServer { 私有MyTestServer（IWebHostBuilder）：基本（生成器） { TestHelperSettings=UriTestHelperSettings.Default； } public UriTestHelperSettings TestHelperSettings{get；} 公共静态MyTestServer Create（），其中TStartup:class { var builder=新的WebHostBuilder（） .ConfigureAppConfiguration（（上下文，配置）=> { config.AddJsonFile（“appsettings.Test.json”，false）； }) .UseStartup（） .使用环境（“开发”）； var testServer=新的MyTestServer（构建器） { ApiExporer=UriTestHelpers.ApiExplorer }; 返回testServer； } 公共IApiDescriptionGroupCollectionProvider ApiExporer{get；private set；} 公共静态MyTestServer Create（）=>Create（）； } 而我的尝试，其中一个转换它看起来像这样：
