Return value from function and start a task

Question

Is it possible to have a function like this

public string Foo()
{
    Task.Factory.StartNew(Foo2());
    return "computedUniqueId";
}

The thing is that I want to start that Foo2 task AFTER Foo returns a value. The reason I ask this is that caller of Foo() function will be listening for information with that "computedUniqueId". Foo2() will trigger that information so there could be a situation that listener would not not what to wait for and will miss that message. So to summarize: Is there something(like continueWith) that will assert that Foo() returns its value before Foo2() kicks in ?

Answer 1

That's not possible because return is the last thing that happens in that method. After a return, the method in question has relinquished control and scope back to the caller. Period. The best I can think of is if you call Foo2 from where ever the string "computerUniqueId" is getting returned to.

Maybe if you supply more details we can help out more. Thanks.
