+    Этот файл содержит директивы среды выполнения, спецификации о типах, к которым получает доступ приложение
+    через отражение, и другие динамические шаблоны кода. Директивы среды выполнения используются для управления
+    оптимизатором .NET Native, а также чтобы не удалить код, к которому обращается ваша библиотека. Если
+    библиотека не выполняет отражение, обычно изменять этот файл не нужно. Но
+    если библиотека отражает типы (особенно типы, переданные в нее или наследуемые из ее типов),
+    следует написать директивы среды выполнения.
+
+    Чаще всего отражение используется в библиотеках для обнаружения информации о типах, переданных
+    в библиотеку. У директив среды выполнения есть три способа выражения требований к типам, переданным в
+    библиотеку.
+
+    1.  Parameter, GenericParameter, TypeParameter, TypeEnumerableParameter
+        Используйте эти директивы для отражения типов, переданных в виде параметров.
+
+    2.  SubTypes
+        Используйте директиву SubTypes для отражения типов, наследуемых из другого типа.
+
+    3.  AttributeImplies
+        Используйте директиву AttributeImplies, чтобы указать, что библиотеке необходимо отразить
+        типы или методы, снабженные атрибутом.
+
+    Дополнительные сведения о написании директив среды выполнения для библиотек:
