title: Runtime C# knowing if 32-bit or 64-bit version of COM Interface is being used
body: <p>I want to build a DLL Class Library use COM Interop, with C#, target ANY CPU, and register it as 32-bit and 64-bit interfaces. </p>
  
  <p>I want to be able to, at runtime, display what interface was used - if I am using the 32-bit version, or 64-bit version.</p>
  
  <p>Any ideas?</p>
