host.RunAsService() not found

[johnsrude]

I am setting up a webserver for internal use using ASP.Net Core 2.x so I want to run it as a service.

I am following the instructions Host an ASP.NET Core app in a Windows Service:

public static void Main(string[] args)
{
    var pathToExe = Process.GetCurrentProcess().MainModule.FileName;
    var pathToContentRoot = Path.GetDirectoryName(pathToExe);

    var host = WebHost.CreateDefaultBuilder(args)
        .UseContentRoot(pathToContentRoot)
        .UseStartup<Startup>()
        .UseApplicationInsights()
        .Build();

    host.RunAsService();  <------- NOT FOUND
}

The problem is that RunAsService is undefined. I have with the same code been able to run host.Run() though.

Here is the project file:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <StartupObject></StartupObject>
  </PropertyGroup>

Do you have a Net Core app or a Net4x app? RunAsService is only available for Net4x.

[johnsrude]

It's Net Core. Do I have to go through the whole reverse proxy thing to get this to work, then?

[Tratcher]

@johnsrude reverse proxies aren't involved here, the components needed for windows service support haven't been ported to .NET Core yet. You can use ASP.NET Core in a console application targeting .NET Framework 4.x to get windows service support.

You could also try 2.1.0-preview1, .NET Core support has been added there. #1189

Or you can use the excellent package by @dasMulli that provides windows services in .net core ;)

[dergroncki]

Change the target framework to <TargetFramework>net461</TargetFramework> in the csproj-file of your application.

You need to install the NuGet package Microsoft.AspNetCore.Hosting.WindowsServices.

Add the following using statement to program.cs: using Microsoft.AspNetCore.Hosting.WindowsServices;

After this the methode "RunAsService()" will be available:

@johnsrude If you'd like to use this on .NET Core, you'll have to move to 2.1.0-preview2.

We decided not to bring this back to 2.0.x (#1229)
