proper way to return monotouch asynchronous calls

Lets say i have an asynchoronous call in my monotouch project like this

context.getNameCompleted += HandleContextgetNameCompleted;
context.getNameAsync();

void HandleContextgetNameCompleted(object sender, getNameCompletedEventArgs args)
    {
        string name = args.Result;
    }

Now how do I get another asynchronous method running that relies on the completion of the first without getting the program to crash. So for instance my second call might be

context.getAgeCompleted += HandleContextgetAgeCompleted;
context.getAgeAsync();

void HandlegetAgeCompleted(object sender, getAgeCompletedEventArgs args)
    {
        string age = args.Result;
    }

the second method can only return a value once we return the "name" from the first person. Please provide in reasons and/or examples of how to properly use this method or any alternate solution.As usual your help is much appreciated

Fire the 2nd request when you handle the completion of the first one.

void HandleContextgetNameCompleted(object sender, getNameCompletedEventArgs args)
    {
        string name = args.Result;

        context.getAgeCompleted += HandleContextgetAgeCompleted;
        context.getAgeAsync();

    }
