+## 'ReadOnlySpan<>' could not be found
+В версии юнити 2020.1.х в консоли может выпадать ошибка:
+```
+The type or namespace name 'ReadOnlySpan<>' could not be found (are you missing a using directive or an assembly reference?)
+``` 
+Чтобы починить добавте директиву `ENABLE_DUMMY_SPAN` в `Project Settings/Player/Other Settings/Scripting Define Symbols`.
