c# - .NET Core program.cs 和 Startup.cs 未命中

Question

我的应用程序有一个大问题。当我使用 IIS Express 时，一切正常，但如果我使用 IIS 启动应用程序（无论是否使用 Visual Studio），Program.cs和Startup.cs都会被忽略，因此应用程序无法正常工作。

.NET Core 2.2 和 .NET Core 3.1 以及 Razor Pages 或 MVC 项目都会发生这种情况。

奇怪的是，IIS 一直工作到昨天，而我没有做任何更改，只是在两天之间重新启动了计算机。这在我的笔记本电脑和台式电脑中都有。

我不明白为什么，但这让我发疯。您对解决问题有什么建议吗？

程序.cs

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args)
            .Build()
            .Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });
}

启动.cs

    public const string GenericCookieScheme = "XXX";
    public const string AuthSecret = "XXX";

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;

Answer 1

你的清单：

• 如果 IIS 可以处理 ASP.NET Core 的请求？
• 如果 IIS 知道它需要处理对 ASP.NET Core 的请求？

对于第一项

请检查您的 IIS 是否已hosting bundle for ASP.NET Core安装。

在这里检查：

如果没有，请在此处下载并安装：

https://dotnet.microsoft.com/download/dotnet-core/thank-you/runtime-aspnetcore-3.1.3-windows-hosting-bundle-installer

第二项

请检查是否有一个名为的文件web.config位于您网站的根文件夹中：

它的内容应该是这样的：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\Aiursoft.Account.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>

检查零件：<aspNetCore>下<system.webServer>。
