Determine if NAV2009 RTC supports DotNet

wakestar

Hi there

Back in the days with NAV2009 there was a RTC Version (SP1) which did not support the DotNet datatype.
.NET Interop was introduced with R2 (iirc)

Is there a safe way to determine by code whether the running client is supporting DotNet?

I need something like this:

IF not ISSERVICETIER THEN
  UseComAutomation()
else begin
  if not DotNetIsSupported then
    UseComAutomation()
  else
    UseDotNetInterop()
end;
