Solved... Issue mainly due to developer (i.e. me) stupidity.
There is no failure. If I attach a debugger to the windows service and try to call a method of the type in the immediate window it will fail as stated. If I call the method in the code itself and then examine the value then it works just dandy. You live, you learn... thanks to those that replied for your time - apologies it was a bit of a wild goose chase!
