title: What do these properties mean in Mono.Cecil?
body: <p>I am using Lokad shared libraries, which in turn depends on Mono.Cecil.</p>
  
  <p>I am a little confused what the following properties mean (they are to do with .NET internals and thus have equivalent .NET internals):</p>
  
  <ul>
  <li>PackingSize (they are to do with types as it is in TypeDefinition).</li>
  <li>Mvid (in ModuleDefinition).</li>
  <li>ExplicitThis (something to do with the this keyword I know, but in
  MethodDefinition).</li>
  <li>CallingConvention.</li>
  <li>GetSentinel (a method which returns int in MethodReference).</li>
  <li>RVA.</li>
  <li>SemanticsAttribute.</li>
  <li>IsHideBySig.</li>
  </ul>
  
  <p>Any idea what these mean/do?</p>
