title: Getting: Could not load file or assembly 'Interop.Shell32' or one of its dependencies after converting a project to .NET 4.0
body: <p>Getting: Could not load file or assembly 'Interop.Shell32' or one of its dependencies after converting a project to .NET 4.0
  It used to work fine in .NET3.5
  I have my IIS 7 pool set to allow 32bit executables.
  Just as before my projects are targeted as 'Any CPU'
  Has anyone ever faced this error before? I'm seeing different Could not load errors but none quite like this one.</p>

  LOG: User = IIS APPPOOL\ASP.NET v4.0

   (Partial)
  WRN: Partial binding information was supplied for an assembly:
  WRN: Assembly Name: Interop.Shell32 | Domain ID: 11
  WRN: A partial bind occurs when only part of the assembly display name is provided.
  WRN: This might result in the binder loading an incorrect assembly.
  WRN: It is recommended to provide a fully specified textual identity for the assembly,
  WRN: that consists of the simple name, version, culture, and public key token.

  <p>Is it something I can set in my machine.config?</p>
