problem with start metod (base.Start()) RRS feed

  • Question

  • Hi,
    I am reading book "Programming Microsoft Robotic Studio" by Sara Morgan and I stopped on chapter 6: Autonomous Roaming. When I am trying to execute first service from this chapter, I am getting this exeption:

    Dssp operation handlers must have a single parameter.Method:System.Collections.Generic.IEnumerator`1[Microsoft.Ccr.Core.ITask] DriveRobot(Double, Double)

    This exeption is thrown by metod Start, precisly base.Start().

    Does anybody know what can be wrong and how to fix it?

    Maybe it is something with that I am programming in v2.0 and this example is in 1.5.

  • Can you paste in the code for that service?  (I don't have my book handy).  All that should be necessary is the main operations port, message definitions, and message handler stubs.

    It sounds like you might be missing or have a duplicated message handler.
