How Do I Debug a Connector Manually?

Answer

If you run into an issue that a connector is not configurable when selected in Data Integration Wizard, use following code in any OnLoad event and look at the error message:

try
{
XMConnect.Connector plug = (XMConnect.Connector)Activator.CreateInstance(Type.GetType("TYPE CONNECTOR ASSEMBLY NAME HERE"));
Dictionary<string, string> constructorParams = new Dictionary<string, string>();//add all required settings
constructorParams.Add("SETTINGNAME", "SETTINGVALUE");
plug.SetHiddenParams(constructorParams);
List<InitializingParameter> initializingParameters = plug.GetInitializingArgumentsList();
throw new Exception("***" + initializingParameters.Count + " parameters found***" );//success
}
catch(Exception ex)
{
throw new Exception(ex.Message + "\n" + ex.StackTrace);
}
