I don't know of anything that can make this run faster in parallel code. A normal for loop is about the fastest this is going to get for two reasons.

1. There is more overhead in a parallel loop than a normal loop.
2. Writing to the same console in parallel won't speed it up because we are being limited by the I/O stream, not the CPU.

If you were doing actual computation inside the body of the loop, we might be able to help you speed it up by running the loops in parallel.

The sort answer is no. You cannot speedup the body of this specific loop by running it in parallel.

Line objects have an X1, X2, Y1, and Y2 properties. I had to do this for work, and using those properties to set the endpoints of the line worked pretty well. I have to warn anything in the negatives might not be visible because a lot of controls don't render things that are outside of them. And, you might want to increase the width and height of the canvas a bit.

1. Do you want to add a new control every-time a button gets clicked?
2. Are there any controls you want to remove when a button gets clicked?
3. Are you saying you have different controls, and the one that gets added is dependent on which button is clicked?

Do any of those properties lead to things like images because that can really slow things down. Are you doing anything that may disable UI virtualization? Why aren't you binding it an ObservableCollection?
