  • This MSDN article is useful.
  • This blog has some good .NET 64-bit information.
  • Run the built-in or standalone FxCop and fix all its 64-bit warnings, especially around P/Invoke.
  • EDIT: Be careful if you use IntPtr in your code, or call into an x86 compiled assembly.

That's it, really. As long as you heed the FxCop warnings and also recompile your code (to avoid the 32-bit WOW layer), you should be fine.
