title: "IServiceCollection" doesn't contain any definition for "AddOcelot"
body: <p>I have a problem to implement Ocelot with .NET Core 3.0, when I try to add ocelot in my program class as the documentation specifies that should be done vs2019 shows me this error:</p>
  
  <blockquote>
    <p>"IServiceCollection" doesn't contain a definition for "AddOcelot" or an accessible extension method "AddOcelot" that accepts a first argument of type "IServiceCollection" (is any directive using or an assembly reference missing?), </p>
  </blockquote>
  
  <p>This error is also repeated for <code>UseOcelot()</code> method</p>
  
  <pre><code>public class Program
  {
      public static void Main(string[] args)
      {
          new WebHostBuilder()
              .UseKestrel()
              .UseContentRoot(Directory.GetCurrentDirectory())
              .ConfigureAppConfiguration((context, config) =&gt; 
              {
                  config
                      .SetBasePath(context.HostingEnvironment.ContentRootPath)
                      .AddJsonFile("appsettings.json", true, true)
                      .AddJsonFile($"appsettings.{context.HostingEnvironment.EnvironmentName}.json", true, true)
                      .AddJsonFile("ocelot.json")
                      .AddEnvironmentVariables();
              }).ConfigureServices(s =&gt; {
                  s.AddOcelot().AddConsul();
              }).ConfigureLogging((hostingContext, logging) =&gt;
              {
                  logging.AddConsole();
              })
              .UseIIS()
              .Configure(app =&gt;
              {
                  app.UseOcelot().Wait();
              })
              .Build().Run();
      }
  }

  <p>what can I do to solve this Error?, I already installed the Nuget packages Ocelot version 13.8.0 and Ocelot.Provider.Consul version 13.8.0.</p>
