title: How to add only executing assembly in CompositionContainer without add AssemblyCatalog
body: <p>Good day.</p>
  
  <p>I need to be added executing assembly in CompositionContainer (MEF) without add AssemblyCatalog. Since this assembly has 20 reference on other project.  </p>
  
  <p>At now, I'm use next solution:</p>
  
  <pre><code>AssemblyCatalog asCatalog = new AssemblyCatalog(Assembly.GetExecutingAssembly());
  AggregateCatalog agCatalog = new AggregateCatalog();
  agCatalog.Catalogs.Add(asCatalog);
  </code></pre>
  
  <p>Thanks for help.</p>
