如何修复“无法加载共享库'httpapi.dll'或其依赖项之一”

Question

我是linux的新手。 但是我需要在此操作系统上运行asp net core应用程序。 我在Windows 10中成功构建和编译应用程序，但是当我将其移至linux并尝试运行时出现以下异常

Application startup exception: System.TypeInitializationException: The type initializer for 'Microsoft.AspNetCore.Server.HttpSys.HttpApi' threw an exception. ---> System.DllNotFoundException: Unable to load shared library 'httpapi.dll' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libhttpapi.dll: cannot open shared object file: No such file or directory

   at Microsoft.AspNetCore.Hosting.Internal.WebHost.EnsureServer()
   at Microsoft.AspNetCore.Hosting.Internal.WebHost.BuildApplication()

而且我确实需要使用httpSys驱动程序。 那是我的代码

 public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .UseHttpSys();

您不能在Linux上运行Http.sys，它是Windows托管选项。请参阅文档 。

Http.sys与Windows（以及IIS，即Microsoft Web服务器）紧密耦合。

对于Linux，您必须使用Kestrel。
