I personally prefer to use the System.Collections.Generic.List<>, so here is my solution.
At the top with the rest of the using statements, add:
using S = System.Collections.Generic;
Now when you want to use the System List, you just type:
S
.List<string> myList
= new S
.List<string>();
It is not perfect by any means, but it is easier than typing out the full namespace every time. I just wonder why Aren has named his class in TNet List<> when in NGUI he has another one called BetterList<>. Maybe they could be consolidated into one class into part of something like "Tasharen Standard Assets"?
