How to determine if an assembly is compiled as 32-bit or 64-bit

1. Go to VS Command Prompt
2. Execute the following: "dumpbin /headers mydll.dll" (of course replacing 'mydll.dll' with your assembly filename
3. Check the FILE HEADER VALUES and look for the value behind machine (x64 = 64-bit and x86 = 32-bit)
