title: How to Tell if a .NET Assembly Was Compiled as x86, x64 or Any CPU
body: <p>What's the easiest way to discover (without access to the source project) whether a .NET assembly DLL was compiled as 'x86', 'x64' or 'Any CPU'?</p>
  
  <p>Update: A command-line utility was sufficient to meet my immediate needs, but just for the sake of completeness, if someone wants to tell me how to do it programmatically then that would be of interest too, I'm sure.</p>
