Hi there - I'm Aly,
I've seen your post and I'm interested. I've had much experience in C#; including much WPF experience. I'm not sure what did you mean by "double array" is it a jagged array, 2D array, or 1D array of point? I'd like to know more about the task(s) ahead of us. Feel free to contact me so we can talk further.
Sincerely,
Aly El-Haddad
