Hi,
I am using a timer , copied directly from your script , only difference is that initialisation is done in Initialise ().
Here is the code.
Everything is working fine, except that the timer is getting fired twice.
1) why is that System.Timer does not work , but System.Windows.Forms timer works
2) why is the timer getting fired twice, i tried changing
var instance = new TestLinkedList(), to another instance of some empty strategy, but i cant understand why the timer is getting fired twice.
Everything works under visual studio.. I have checked individual logic.
The Print("here") along with the time is getting printed twice.
Please help
