On the properties page of your Pega Robotics project you need point your project at the WorkGroup. Also, make sure you are running the solution from the Pega Robotics Runtime - it will not attach to the console if run from Pega Robotics Studio.
Thanks Jeff that helped a lot. Additionally we had to set view RPACredentials to true in RuntimeConfig.xml so we could set the login data for our Pega server. Is there a more direct way to set the credentials?
