Async calling as it was ment to be.

tasks.cs

//http://msdn.microsoft.com/en-us/library/dd537609.aspx
Task[] tasks = new Task[3]
{
    Task.Factory.StartNew(() => MethodA()),
    Task.Factory.StartNew(() => MethodB()),
    Task.Factory.StartNew(() => MethodC())
};

//Block until all tasks complete.
Task.WaitAll(tasks);
