Shortly that an indepenciente application connects with this connection string but a service not[code]....

I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I'm working on a CNC control program, based on a DLL that someone else wrote. No problems with that sofar, as i get good support from the writer.
The problem i do have to tackle is the following: I want to acces all the functions by means of softkeys ( the F-Keys at the top of our keyboards ) when the program starts it shows the Main menu softkeys ( F1-F12), and each F-key has a function assigned to it, some will make the machine move, others will show another menu, or a fileopen/save dialog, depending on the chosen keys.
All works fine and handy-dandy, except for the F10 key, it seems to be "Sticky", when i press it, the program will not react to any other key, only the F10 key can get it back in "normal state" accepting every key with a function assigned..
How to "unstick" the F10 after pressing it?.. because pressing F10 now, means no other key will do anything, and that may become dangerous, when the machine is moving and it must be stopped..
