Question

I am trying to call DoCallBack for multiple AppDomains, but it is not asynchronous. Is there a way to make the calls asynchronous? Here is what I am attempting to do:

        var appDomain1 = System.AppDomain.CreateDomain("event1");
        var appDomain2 = System.AppDomain.CreateDomain("event2");

        Console.WriteLine("Executing appDomain1");
        appDomain1.DoCallBack(new CrossAppDomainDelegate(Event));
        Console.WriteLine("Executing appDomain2");
        appDomain2.DoCallBack(new CrossAppDomainDelegate(Event));

I am attempting to execute the method “Event” in multiple appDomains asynchronously.

You could use the TPL, and call DoCallBack from a Task:

var task1 = Task.Factory.StartNew(() => appDomain1.DoCallBack(Event));
var task2 = Task.Factory.StartNew(() => appDomain2.DoCallBack(Event));
Task.WaitAll(task1, task2);
