FileVersionInfo behaves differently between a dll run from a WPF application and a command line application

Question

I'm writing a dll which will be used in several environments, namely from our build machine. The program is responsible for getting a file's FileVersion. I'm using the following code within the .dll:

public string GetVersion(string filePath)
{
  FileVersionInfo temp = FileVersionInfo.GetVersionInfo(filePath);
  return temp.FileVersion;
}

Now when I run this function from the WPF test application I wrote everything works correctly; all values are filled out for the FileVersionInfo object.

However when I run this exact same function from within a Console Application project all the values in the FileVersionObject are null.

Anyone have any idea what's going on?

This question has some interesting suggestions, but it doesn't look like the issue was ever solved: http://stackoverflow.com/questions/2221598/fileversioninfo-getversioninfo-incorrect-in-console-application — George, Oct 01 '12 at 13:14

I figured it out actually, the way I was retrieving the file path from the console was incorrect, I had a space character at the end of the directory name. I feel pretty dumb about it o.O

Which is odd, because File.Exists passed on this incorrect path, and the FileVersionInfo.GetVersionInfo didn't throw an error on it either. – Ben K. Oct 01 '12 at 13:42
