BA As hard as we tried in the BCL design to be language-neutral, sometimes it was just impossible. The name of this exception seems obvious to most C# or C++ developers but not to a VB developer. The VB language uses the keyword “Nothing” to represent this concept. So getting a NullReferenceException frequently does not help the VB user determine what the problem is.
