The <code>ConfigureServices(IServiceCollection services)</code> method is meant to configure your application's services as explained in the <a href="https://docs.microsoft.com/en-us/aspnet/core/fundamentals/startup?view=aspnetcore-2.1#the-configureservices-method" rel="nofollow noreferrer">Microsoft documentation</a>.

In there, it does not seem you can retrieve scheme, host and port information from the <code>WebHost</code> directly.
Indeed, you normally create your <code>WebHost</code> in <code>Program.cs</code>:

<pre><code>var webHost = WebHost.CreateDefaultBuilder(args) // initialise web host
 .UseStartup&lt;Startup&gt;()
 .Build();
</code></pre>

However, you may retrieve scheme, host and port used by the <code>WebHost</code> by looking at the very same configuration the <code>CreateDefaultBuilder()</code> is using to do so.

Indeed, looking into the <a href="https://github.com/aspnet/MetaPackages/blob/dev/src/Microsoft.AspNetCore/WebHost.cs#L150" rel="nofollow noreferrer"><code>WebHost</code> code</a>, you can see <code>CreateDefaultBuilder()</code> loads configuration from both <a href="https://github.com/aspnet/MetaPackages/blob/dev/src/Microsoft.AspNetCore/WebHost.cs#L171" rel="nofollow noreferrer"><code>appsettings.json</code></a> and <a href="https://github.com/aspnet/MetaPackages/blob/dev/src/Microsoft.AspNetCore/WebHost.cs#L172" rel="nofollow noreferrer"><code>appsettings.Development.json</code></a> to configure the <code>WebHost</code>, as for example scheme, host and port. You may very well look at the same configuration data in <code>ConfigureServices(IServiceCollection services)</code> and deduct the same configuration information.

If you are targeting Asp.Net Core 2.1, you can <a href="https://docs.microsoft.com/en-us/aspnet/core/fundamentals/servers/kestrel?view=aspnetcore-2.1&amp;tabs=aspnetcore2x" rel="nofollow noreferrer">configure your endpoints</a> in <code>appsettings.json</code> file directly. You may do the same in your <code>ConfigureServices(IServiceCollection services)</code> by looking into the <code>Configuration</code> property in <code>Startup.cs</code>.

Your <code>Startup.cs</code> may look as follows:

<pre><code>public class Startup {

 public Startup(IConfiguration configuration) {

 Configuration = configuration;

 }

 public IConfiguration Configuration { get; }

 public void ConfigureServices(IServiceCollection services) {

 // get http url
 var httpEndpoint = Configuration["Kestrel:Endpoints:Http:Url"];

 // get https url
 var httpsEndpoint = Configuration["Kestrel:Endpoints:Https:Url"];

 /*
 * Use IConfiguration to retrieve information
 * about loaded configuration.
 */

 // Add framework services.
 services.AddMvc();

 }

 public void Configure(IApplicationBuilder app, IHostingEnvironment env) {

 if (env.IsDevelopment()) {
 app.UseDeveloperExceptionPage();
 }

 app.UseMvc();

 }

}
</code></pre>

Take a look at the <a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.configuration.iconfiguration?view=aspnetcore-2.1" rel="nofollow noreferrer"><code>IConfiguration</code> Microsoft documentation page</a> for more information about what methods you can use to read configuration data.

I needed to access the port inside ConfigureServices for a Service Fabric stateless application hosted in Kestrel.

One approach (<a href="https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-tutorial-dotnet-app-enable-https-endpoint" rel="nofollow noreferrer">ref</a>) is to put the thing you were going to do in your Startup, in to where you build you WebHost, in Programs.cs (in my case the CreateServiceInstanceListeners of my Service Fabric StatelessService)

This is a snippet from what I was working on:

<pre><code> var endpoint = Context.CodePackageActivationContext.GetEndpoint("ServiceEndpoint");
 return new WebHostBuilder()
 .UseKestrel(/* SSL STUFF GOES HERE */)
 .ConfigureServices(
 services =&gt; services
 .AddSingleton&lt;StatelessServiceContext&gt;(serviceContext)
 .AddMvc(options =&gt;
 {
 // Using the port here:
 options.SslPort = endpoint.Port;
 options.Filters.Add(new RequireHttpsAttribute());
 })) 
 .UseStartup&lt;Startup&gt;()
 .UseServiceFabricIntegration(listener, ServiceFabricIntegrationOptions.None)
 .UseUrls(url)
 .Build();
 }))
</code></pre>

I need to get dynamically value of host (including scheme) and port from <code>public void ConfigureServices(IServiceCollection services)</code>. I was trying to do that through <code>IServerAddressesFeature</code>, but when I tried to resolve it the IoC returned null (it is not registered so far). So, is there any other option to get this info?
