Delayed function calls

Question

Is there a nice simple method of delaying a function call whilst letting the thread continue executing?

e.g.

public void foo() {     // Do stuff!      // Delayed call to bar() after x number of ms      // Do more Stuff }  public void bar() {     // Only execute once foo has finished } 

I'm aware that this can be achieved by using a timer and event handlers, but I was wondering if there is a standard c# way to achieve this?

If anyone is curious, the reason that this is required is that foo() and bar() are in different (singleton) classes which my need to call each other in exceptional circumstances. The problem being that this is done at initialisation so foo needs to call bar which needs an instance of the foo class which is being created... hence the delayed call to bar() to ensure that foo is fully instanciated.. Reading this back almost smacks of bad design !

EDIT

I'll take the points about bad design under advisement! I've long thought that I might be able to improve the system, however, this nasty situation only occurs when an exception is thrown, at all other times the two singletons co-exist very nicely. I think that I'm not going to messaround with nasty async-patters, rather I'm going to refactor the initialisation of one of the classes.

Thanks to modern C# 5/6 :)

public void foo() {     Task.Delay(1000).ContinueWith(t=> bar()); }  public void bar() {     // do stuff }
