I have an event that closes the main form (the app essentially).

However the app could be busy (same thread) with 2 potentially long running methods called from a timer.

When Close() is called (from another class or from a callback in the same form) does it wait for these methods to complete?

No. But you can handle the closing event and set the flag in the closingeventargs passed in to not close the app.

Figured..

Going to have to re-design to:

Method1();

Method2();

this.Close();
