title: .NET version assembly was compiled with (target version)
body: <p>once upon a time a long, long time ago we used to see the .net version a library (dll) or executable was compiled with when you viewed the files properties via file explorer.
  Now you cant, so what’s the quickest way of checking what version it uses now ?
  I've been playing with various tools like ILSpy, but I need to have something that’s just easy to install like a reg entry so I can right click and view version.</p>
  
  <p>We have loads of files on multiple servers, including client servers. Sometimes we need to ask what version are you running, at the moment its proving difficult.</p>
  
  <p>any ideas ?</p>
