title: ServiceBehaviorAttribute config for WCF server on DotNet Core
body: <p>I'm migrating a small .NET standard SOAP project to NetCore 3.1 with SoapCore.</p>
  <p>On my original project I have this single threading configuration:</p>
  <pre><code>[ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Single)]
  public class BehaviorService : IBehaviorService
  {}
  </code></pre>
  <p>However I can't find an equivalent for my version on NetCore.</p>
  <p>Is this feature supported or is there a workaround to do this implementation?</p>
