 Real ECS framework for c\#. Enables to write encapsulated, decoupled, maintainable, highly efficient, data oriented, cache friendly, multi-threaded (if used with Svelto.Tasks), code without pain. Although the framework is platform agnostic \(compatible with c\# 7 and .net standard 2.0\), it comes with several Unity extensions.
 
+#note: this version needs the support of the unity collections package to work.

 ## Why using Svelto.ECS with Unity?
 
 _Svelto.ECS wasn't born just from the needs of a large team, but also as result of years of reasoning behind software engineering applied to game development\(\*\). Compared to Unity.ECS the main goals and reasons for Svelto.ECS to exist are different enough to justify its on going development \(plus Svelto is platform agnostic, so it has been written with portability in mind\). Svelto.ECS hasn't been built just to develop faster code, it has been built to help develop better code. Performance gain is one of the benefits in using Svelto.ECS, as ECS in general is a great way to write cache-friendly code, but the main reasons why Svelto.ECS has been developed orbit around the shifting of paradigm from Object Oriented Programming, the consequent improvement of the code design and maintainability, the approachability by junior programmers that won't need to worry too much about the architecture and can focus on the solution of the problems thanks to the rigid directions that the framework gives. Svelto.ECS is the result of years of iteration of the ECS paradigm applied to real game development with the intent to be "junior coder proof"._
