title: What are Complex Types in Context with Entity Framework
body: <p>Right now I am learning a lot about the Entity Framework from Videos on Pluralsight, so excuse my Question which might look newbish but I can not understand what Complex Types are or why I would need them. </p>
  
  <p>I do know that  I have to map them via Annotations or Fluent Api something like this:</p>
  
  <pre><code>modelBuilder.ComplexType&lt;blubb&gt;();
  </code></pre>
  
  <p>Maybe someone could elaborate the need of Complex Types for me?</p>
