Thanks for your response, but surely if the .NET Services was not running how can CF instantiate and dump the object with all the correct methods?
Anyway for some strange reason there is no Coldfusion .NET service in my services control panel even though I am running CF8. I have since downloaded the .NET service installer, run it and done a restart but I can still see no such service and the error continues?
I am running CF8 Dev on IIS 6 – Window XP pro and here is debug
