How to fix "Unable to load shared library 'httpapi.dll' or one of its dependencies"


I'm a new in linux. But I need to run asp net core app at this os. I build and compile app successfuly in windows 10, but when I move this to linux and try to run get following exception

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.BuildApplication()

And I really need to use httpSys driver. That is in my code

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

Solution

  • You can't run Http.sys on Linux, its a windows only hosting option.See the documentation.

    Http.sys is tightly coupled to windows (and IIS, which is the Microsoft Webserver).

    For Linux you have to use Kestrel.
