title: Add scoped service when creating a new scope
body: <p>Is it possible to add a service to an <code>IServiceProvider</code> when creating a new scope?</p>
  
  <p>E.g. a scope is created like this:</p>
  
  <pre><code>using (var scope = Services.CreateScope())
  {
      // Register some service using "AddScoped"
      scope.??.AddScoped&lt;IOrganizationIdProvider, OrganizationIdProvider&gt;((x) =&gt; { return new OrganizationIdProvider("dynamic-parameter")});
  
      // Resolve service
      scope.ServiceProvider.GetService&lt;IOrganizationIdProvider&gt;();
  
  }
  </code></pre>
  
  <p>The service should be resolved when creating new instances in the scope.</p>
