This is because the event handler for E is asynchronous and the assertion is executed in a different task. The assertion should be executed after the event handler for E has completed execution. To do this, we can use the MonitorAction attribute to specify that the assertion should be executed in the context of the event handler for E. The following code shows how to use the MonitorAction attribute:51using Microsoft.Coyote.Actors.SharedObjects;52using System;53using System.Threading.Tasks;54using Microsoft.Coyote;55using Microsoft.Coyote.Actors;56using Microsoft.Coyote.Specifications;57{
