asp.net-core - 无法在 IIS 上托管 .Net Core 3.1 Web API
问题描述
我将 .net core 2.2 web api 升级到 .net core 3.1。我现在可以使用 控制台从控制台运行它dotnet myapi.dll，但是当我尝试在 ISS 上托管它时，出现以下异常。
我已经安装AspNetCore Module V2并且这个模块抛出异常，我无法理解缺少的部分。
Autofac.Core.DependencyResolutionException: An exception was thrown while activating ?:Microsoft.Extensions.Hosting.IHostedService[] -> Microsoft.AspNetCore.Hosting.GenericWebHostService -> Microsoft.AspNetCore.Server.IIS.Core.IISHttpServer.
---> Autofac.Core.DependencyResolutionException: An exception was thrown while invoking the constructor '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
Host.CreateDefaultBuilder(args)
.UseServiceProviderFactory(new AutofacServiceProviderFactory())
.ConfigureWebHostDefaults(webHostBuilder =>
{
webHostBuilder
.UseStartup<Startup>();
})
.Build()
.Run();
以下是我的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();
});
}
调用AddNLog()是我们的客户实现来覆盖 .net 核心提供的记录器。
我使用paket而不是nuget所以以下是我的paket.dependencies文件。

我探索了一下，并没有找到太多帮助。我创建了一个新的 asp.net core web api，我看到该模板带有或多或少相似的配置。我在这里想念什么？
解决方案
删除 Microsoft.AspNetCore.* nuget 包，这些包在 3.0 中不再存在，因此您将使用 2.x 版本。 https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-3.1&tabs=visual-studio#remove-obsolete-package-references
