namespace CreateAppointment
{
public class CreateAppointmentPlugin : IPlugin

ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
