windows: XP -> current: how to tell if in CONSOLE or RDP session?

I have a messy collection of Windows platforms in various labs. Everything from XP to the latest. I have a simple C#/.NET app that runs at user login and logout. I need to differentiate between true Console logins and RDP sessions. I am using 

System.Diagnostics.Process.GetCurrentProcess().SessionId

to get a sessionId but I don't see anything that says "you are on the Console" or "you are in an RDP session". Is there such a thing?

For my needs it turns out that the windows environment variable %sessionname% holds the info I am looking for. In my C# code I can say:

string sessionName = Environment.GetEnvironmentVariable("SESSIONNAME")
                     ?? "CONSOLE";

%sessionname% seems to hold either the string "console" or "rdp-(something)#(number)", ex "rdt-tcp#1234". I don't know the whole range of possible values but it looks like it will work for my needs.

You can determine which session ID (if any) is currently attached to the physical console by calling the WTSGetActiveConsoleSessionId() function.
