✅ Thread-safe list

I'm trying to turn a piece of code which just calls a list of tasks asynchronous. Each of these tasks writes to a

List<T>

List<T>

passed to all the tasks. I'm using

Task.WhenAll

Task.WhenAll

to run all the tasks in parallel, however I'm unsure of whether using a regular

List<T>

List<T>

is fine or if I should be using something else.
