Why can't isFunctionAvailable() find this function?

I’m trying to check if the function GetHashCode is available on a Windows machine and, for some reason, I can’t detect it with isFunctionAvailable(). Here is what I’m doing:

if (System.isFunctionAvailable("GetHashCode", "mscorlib") then MsgBox("The function is available") else MsgBox("The function is not available") end if

I know that I have the .NET framework installed on this machine so the function should be available if I’m understanding correctly. Can anyone explains why this check might be failing?

IsFunctionAvailable doesn’t understand .NET assemblies, only generic DLLs with C-style exported functions.

Ahh, thank you!
