我将我的 .net core 2.2 web api 升级到了 .net core 3.1。现在我可以使用 dotnet myapi.dll 命令在控制台中运行它，但是当我尝试在 ISS 上托管它时，出现以下异常。
我已经安装了 AspNetCore Module V2 模块，但是该模块抛出异常，我无法理解缺失的部分。
Autofac.Core.DependencyResolutionException: 在激活 ?:Microsoft.Extensions.Hosting.IHostedService[] -> Microsoft.AspNetCore.Hosting.GenericWebHostService -> Microsoft.AspNetCore.Server.IIS.Core.IISHttpServer 时抛出异常。
---> Autofac.Core.DependencyResolutionException: 在调用构造函数 'Void .ctor(Microsoft.AspNetCore.Server.IIS.Core.IISNativeApplication, Microsoft.Extensions.Hosting.IHostApplicationLifetime, Microsoft.AspNetCore.Authentication.IAuthenticationSchemeProvider, Microsoft.Extensions.Options.IOptions``1[Microsoft.AspNetCore.Builder.IISServerOptions], Microsoft.Extensions.Logging.ILogger
以下是我的 Program.cs 文件。
Host.CreateDefaultBuilder(args)
.UseServiceProviderFactory(new AutofacServiceProviderFactory())
.ConfigureWebHostDefaults(webHostBuilder =>
{
webHostBuilder
.UseStartup<Startup>();
})
.Build()
.Run();
下面是我的
Startup.cs。public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public ILifetimeScope AutofacContainer { get; private set; }
public void ConfigureContainer(ContainerBuilder builder)
{
// Register your own things directly with Autofac, like:
...couple of my Ioc registrations
}
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddNLog();
services.Configure<IISServerOptions>(options =>
{
options.AutomaticAuthentication = false;
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseEndpoints(endpoints => {
endpoints.MapControllers();
});
}
AddNLog() 的调用是我们客户自己实现的重写 .net core 提供的日志记录器。
我使用 paket 而不是 nuget，因此以下是我的 paket.dependencies 文件。

我进行了一些探索，没有找到很多帮助。我创建了一个新的asp.net core web api，发现该模板具有更或多或少相似的配置。这里我错过了什么？
Autofac.Core.DependencyResolutionException。它出现的原因是在设置此 API 时出现了问题。我无法弄清楚问题出在哪里，因为outprocess（kestrel）托管正常工作，但inprocess托管却不行。 - Pradeep
